Significant Spring Storm Expected to Dump up to 20cm and Possibly Locally Higher Amounts Across the Prairies

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

It’s simply not spring in the Prairies without at least one major snowstorm and this year will be no different! A low pressure system will track across the region over the next couple of days, bringing widespread 10-20cm to all three Prairie provinces by the end of the work week. What makes this storm more interesting is that while some areas could see up to 20cm of snow, others could see temperatures approaching 20°C, particularly in Southern Alberta and Southwest Saskatchewan!

The precipitation will begin Wednesday evening as rain across parts of Central Alberta. As the temperatures fall later in the evening, the rain will transition to snow, which will then spread both southward and eastward overnight and into early Thursday morning. A bit of rain will persist along the southern edge of precipitation into the morning, but it will eventually also transition over to snow, with a chance for some brief freezing rain in between.

It’s during the early morning hours of Thursday that the snow will push into Saskatchewan while also starting to intensify across Central Alberta. As the morning continues, the heavy snow will cross into Saskatchewan, spreading southeastward across the province throughout the remainder of the morning and into the early afternoon. The snow will then spread into Southern Manitoba Thursday afternoon with the heavier snow beginning in the evening.

The heavy snow will fall for several hours, leading to rapid accumulation of up to 20cm across the region, with the possibility of pockets where up to 25cm could fall. The band of heavy snow will start to taper off early Friday morning, but light snow is expected to continue throughout the day, with the possibility of periods of heavier snow in both Saskatchewan and Manitoba.

Model Image showing the location and intensity of snow (Blue), Rain (Green), and Freezing rain (Pink) at 6PM CT Thursday

Wind gusts are expected to be up to 60km/h throughout the event and along with the heavy snow, travel may be difficult at times due to blowing snow. This could result in some isolated road closures in the hardest hit areas so make sure to check your local road conditions before going out over the next few days.

Mid-March Snowfall Will Help Build Back Some Snowpack With 10-20cm Expected Across a Wide Stretch of Alberta & Saskatchewan

While we’re a little over a week away from the official start of spring, a majority of the snowpack is already gone across parts of Alberta and Saskatchewan. However, winter is still hanging on with more snow incoming over the next couple of days.

This will help to add some much-needed moisture to part of the region, especially since we have seen well below average snowfall since November. Unfortunately for Southern Alberta, the driest part of the Prairies, can expect little to none of this incoming moisture.

The snow will cross through the Rockies and into Alberta at around sunrise on Thursday and spread northeastward deeper into the province throughout the morning and into the afternoon. The snow will intensify starting in the early afternoon and this heavier snowfall will continue straight through overnight. This will lead to a large stretch of Central and Northern Alberta receiving 10-20cm of snow and up to 25cm possible to the north of Lake La Biche and Cold Lake through Friday morning.

Model Image showing the location and intensity of snow (Blue) and Rain (Green) at 4PM MT on Thursday

Light snow will make its way into Northern Saskatchewan early Thursday afternoon, followed by the more intense snowfall beginning in the early evening. This area of heavier snow will cross through Saskatchewan in an almost due easterly path and similar to in Alberta, it will dump 10-20cm across a large stretch of the province and up to 30cm from the Alberta border to almost La Ronge by Friday afternoon.

The arrival of additional moisture from a separate low-pressure system in the US on Friday morning makes the forecast in Central and Southern Saskatchewan a bit more complicated. This appears to be bringing a combination of rain, freezing rain, ice pellets, and snow to most of the southern half of the province throughout the morning as it merges with the system from the west.

There is still some uncertainty regarding the precipitation type and the area that could be impacted by the arrival of the secondary system. Therefore, for this forecast, we are only focusing on the snow coming from Alberta and we will cover this additional precipitation in a separate forecast that will be issued later in the day on Thursday

Quick Blast of Intense Snowfall Could Bring Over 20cm to Parts of Saskatchewan and Manitoba

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

February has been a quiet month across the Prairies, as far as active weather is concerned. That has changed though, with the arrival of warmer air in the past few days, which has also brought heavier snowfall back to the region. Now, we are looking at that heavy snow across Saskatchewan and Manitoba for Thursday and Friday.

The snow will begin early Thursday in Northern Saskatchewan and surge southeastward throughout most of the morning, crossing into Manitoba at around 8-9am. The snow will be steady and fairly light for most of the day, falling at up to 2cm/hr, leading to a large swath of over 10cm across both provinces.

In the late afternoon and early evening, the snow will begin to taper off in Saskatchewan while at the same time, intensifying in Central Manitoba. The heavier snow is expected to cross the province throughout the evening and will bring snowfall totals to the higher end of the 10-20cm range, with a strong likelihood of localized pockets of over 20cm, particularly around Flin Flon, The Pas and Norway House. The intensified snowfall will also be associated with some stronger wind gusts of up to 70km/h, which could result in isolated whiteouts due to blowing snow.

As the short-lived system exits the region, the snow will finally taper off in Saskatchewan shortly after midnight on Friday and in Manitoba just before sunrise. The winds are also expected to weaken Friday morning, therefore reducing the blowing snow risk.

Last Year Was a Record-Breaking Tornado Season in Canada, According to Northern Tornadoes Project

/

The Northern Tornadoes Project (NTP), based out of Western University in London, Ontario, has just released their annual report on the 2024 tornado season. In it, the organization highlights that last year was a record-breaking year in terms of the length of the season.

Canada’s first tornado of the year was recorded in Malden Centre, Ontario on March 16th, coincidentally tying a tornado that hit Clifford, Ontario on March 16th, 2016 as the earliest recorded Ontario tornado. There were then a series of several late-season tornadoes that the NTP recorded: three individual twisters in New Brunswick on November 1st and the final tornado of the year near Fergus, Ontario on November 10th.

All told, this makes the 2024 tornado season 240 days long, over a span of nine different months. This is considerably longer than the typical season, which usually only has tornadoes in six separate months, from April to September. At this length, 2024 was the longest tornado season since at least 1980.

Another substantial finding in the report is that the 2024 tornado season was marked by the second-most tornadoes verified by the organization in a single season since their inception in 2017, with 129 tornadoes confirmed nationwide. A large spike in the total number came after the completion of the season, when the team could conduct further investigation and satellite review, which subsequently included an additional 16 tornadoes to the tally!

Most of the year’s tornadoes were rated as weak EF0s and EF1s, but the NTP did record 12 EF2 tornadoes. While this is double the amount from 2023, it is well below the 30+ recorded in both 2021 and 2022, both very active tornado seasons. Of these EF2 tornadoes, all but one (the Wolverton-Ayr tornado in Southern Ontario) occurred in forested areas of Northern Ontario and Quebec.

Geographically, Ontario was the province which was home to the most tornadoes this past season, with 50 tornadoes on land and 10 over water, which makes up almost half of all recorded tornadoes for the year. Out of the 50 tornadoes on land, 14 of them spawned during outbreaks on two individual days: June 29th had six and July 28th had eight. Quebec was the second-most active province, with 21 total tornadoes (four of which occurred over water), followed by Saskatchewan with 19.

At Instant Weather, we are a proud partner of the Northern Tornadoes Project. We developed our custom radar suite, Instant Weather Pro, in conjunction with the organization and the many weather reports from you, our community, help them in their mission.

For the upcoming 2025 season, the Northern Tornadoes Project team sounds excited to continue their work alongside the Northern Hail Project and the newly-founded Northern Mesonet Project. You can learn more about them at the Northern Tornadoes Project homepage and for more information regarding the report, you can find it here.

Bitter Arctic Air and Southern Moisture Will Bring up to 30cm of Snow to the Southern Prairies This Week

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The pattern of active weather across the Prairies will continue throughout the week with a new system moving in from the United States starting late Monday and continuing until Thursday afternoon.

Arctic air flooded southward following the passage of the storm this past weekend and it will have a significant impact on our incoming system. Very cold temperatures result in much higher snow ratios so what may look like a small amount of moisture actually leads to much greater accumulations of dry snow.

This is the situation we will find ourselves in this week. The incoming system doesn’t contain a great deal of moisture, but the cold temperatures, into the -20°s, will cause a significant amount of lightweight, dry snow to fall. Overall, we’re looking at a possibility of a widespread 20-30cm of snow falling across all three Prairie provinces.

The snow will fall mostly at a fairly light rate, however, the winds are expected to pick up overnight Wednesday in Saskatchewan and spreading into Manitoba through Thursday morning. The winds should peak early Thursday afternoon in Central and Southern Manitoba, gusting at up to 50km/h, before dying down in the evening so there could be a brief period of reduced visibility due to blowing snow.

Model Image showing the total amount of precipitation in millimetres

Alberta

Patches of snow will move into Southern Alberta and Southwest Saskatchewan late Monday night from North Dakota. It will spread northward throughout the morning, reaching the Edmonton area around the lunch hour Tuesday.

Later Tuesday afternoon, the snow in Central Alberta and parts of Southern Alberta will taper off, but it will gradually return throughout Wednesday morning as the system reorganizes and the snow becomes steadier. The snowfall across the southern half of the province will continue into early Wednesday afternoon, at which point it will start to dissipate from west to east and finally ending Thursday morning before sunrise.

Model Image showing the location and intensity of snowfall at 5AM MT/6AM CT Wednesday

Saskatchewan

After moving into Southwest Saskatchewan late Monday night, the patchy snow will spread northward and eastward throughout Tuesday morning and into the early afternoon. At that point, it should reach Lloydminster, as well as into the Saskatoon and Regina areas, but not quite to the Manitoba border.

Similar to what is expected to occur in Alberta, the snow along the leading edge is anticipated to dissipate beginning in the mid-afternoon Tuesday and continuing into the early evening before surging back across the province later in the evening. The reorganized snowfall will be much steadier overnight and through to Wednesday afternoon, possibly becoming heavy at times closer to the American border.

The snow will the begin to taper off in the Southwest early Wednesday afternoon as the system travels eastward, ending in Southern Saskatchewan in the late evening. Steady snow is expected to continue across parts of Central Saskatchewan during this period and will eventually start to dissipate through the pre-dawn hours of Thursday.

Model Image showing the location and intensity of snowfall at 8PM MT/9PM CT Wednesday

Manitoba

Snow will move into the Parkland Region from Saskatchewan early Wednesday morning and cross the width of the province thorough the morning and into the early afternoon. At that point, the snow will begin in the Westman region and spread across Southern Manitoba through the remainder of the afternoon and into the evening.

The snow in Southern Manitoba isn’t expected to last too long, with it dissipating from west to east starting in the late evening until the pre-dawn hours Thursday. Like Saskatchewan, the snow will persist across parts of Central Manitoba in the meantime, until early Thursday morning when it starts to taper off. The snow will finally end in Manitoba by noon on Thursday.

Second Day of Snowfall Expected to Bring Widespread 10-20cm of Snow Across the Prairies on Saturday

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The first day of our multi-day snow event brought light to moderate snow to all three Prairies provinces by Friday evening. Snowfall totals for the entire event are still expected to top 30cm across a significant portion of the region, with Saturday’s snowfall bringing over 10cm of accumulation to many.

Before discussing what is expected on Saturday, we first need to determine the positioning of the system at approximately midnight. As seen in the model image below for that point in time, snow will still be falling across most of Northern Alberta and along the Rockies. It will also continue to extend southeastward across Saskatchewan and into Southwestern Manitoba.

Model Image showing the Location and Intensity of the Snowfall at 11Pm MT Friday/12AM CT Saturday

Alberta

The snow will continue across Northern Alberta and the Rockies through the early morning hours of Saturday as the entire system continues to travel eastward. There’s expected to be a break in the snowfall for a few hours from Grande Prairie to Cold Lake through the early morning, but that will be followed by a secondary wave of heavier snowfall trailing closely behind.

This additional area of snow will stretch southward into Central Alberta, bringing more snow to Edmonton and possibly even some light flurries across Southern Alberta throughout the day. The snow will cross this part of the province during the morning and afternoon and by the evening, the band of snow will be almost entirely in Saskatchewan. Snowfall totals for Central and Southern Alberta won’t be too high, with most receiving less than 5cm by the end of the day and the last of the snow they can expected from this event.

Later in the morning, we’ll start to see the snow tapering off in parts of Northern Alberta from west to east, bringing accumulation for this area to 5-10cm. The snow will continue to fall further north; in areas like Peace River, High Level, and Fort McMurray; straight into the overnight hours, bringing snowfall accumulations here up to 30cm by the end of the day.

As the snow clears behind the second wave of snow, Arctic air will flood southward and the temperatures will start to fall into the -20°s,

Model Image showing the Location and Intensity of the Snowfall at 5Am MT/6AM CT Saturday

Saskatchewan

The snow will gradually end in Southern Saskatchewan, from west to east, throughout the early morning hours as the system continues to travel eastward. The same can be said further north in the province, but beginning a couple hours later, closer to sunrise, due to the northwest to southeast orientation of the large band of snow.

The second wave of snow from Alberta will cross into Saskatchewan several hours later, in the mid-morning, which will add to the earlier snowfall across much of the province. Southwest Saskatchewan can expect little to no snow from this, but isolated flurries can’t be completely ruled out. Snowfall is, however, anticipated in the southeast corner of the province as it appears this secondary line will see some southward development as it crosses the province.

By the end of the day, a majority of Saskatchewan will have received at least 5cm of snow, with a significant portion over 10cm. Snow will still be falling across most of the province overnight and into Sunday morning, which will add to the total amount received from the event and will be covered in the next forecast.

Model Image showing the Location and Intensity of the Snowfall at 11Am MT/12M CT Saturday

Manitoba

The snowfall isolated to Southwestern Manitoba late Friday will spread eastward across the southern portions of the province through Saturday morning. Snow will also gradually begin to fall moving northward along the Saskatchewan border as the main band of snow continues along the same eastward trajectory.

This snow may be heavy at times, leading to quick accumulation. The lightest snow will be along the southern edge, which can expect less than 5cm total by the end of the day.

In the late morning, areas in the southwest will see the snow start to taper off as the initial band of snow exits the region. There will be several hours of calm before the second wave moves in during the evening. This wave will only make it about halfway across the province before midnight, so only a small area can expect over 10cm of snow total for Saturday.

Model Image showing the Location and Intensity of the Snowfall at 11Pm MT Saturday/12AM CT Sunday

Sunday

On Sunday, the entire system starts to exit the Prairies followed by temperatures in the -20°s and -30°s across the entire region. There will still be some decent snowfall across the region throughout the day, which we will cover in the forecast that will be posted Saturday evening.

Active Winter Weather Returns to the Prairies With Widespread Snowfall Exceeding 30cm Beginning Friday

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The month of January has been fairly quiet across the Prairies, with periods of frigid Arctic air and some occasional snowfall as well as much more mild temperatures in the past week. Now, to end the month, we’re bracing for the return of the Arctic air and the most impactful storm since November. This incoming system will bring over 30cm of snowfall to a large swath across all three Prairie provinces by late Monday.

Considering how long the snow is expected to fall across the region, we’ll be breaking the forecast down into daily segments.

Friday

The snow will make its way into Alberta in the Northern Rockies ahead of a warm front early Friday morning, a couple of hours after midnight, as a low-pressure system pushes eastward from British Columbia. Meanwhile, snow will also develop along the front further south, to the east of Calgary.

These two areas of snowfall will merge together after a few hours, before sunrise, as the front surges northeastward. At the same time, snow will continue to develop along the length of the front and start making its way into Southwest Saskatchewan.

Model Image showing the Location and Intensity of the Snowfall at 7pm MT/8PM CT

As the low-pressure center makes its way across Alberta Friday morning and afternoon, the large area of snowfall will expand further northward in Alberta and eastward across Saskatchewan. In the evening, the leading edge of the snow will start to cross into Southwestern Manitoba and the entire line of snow will continue to travel eastward as we move into the overnight hours.

The snow is expected to remain steady over an area that covers Grande Prairie and east to Lac La Biche from the late morning straight through to the end of the day, which will lead to this area receiving the greatest accumulation of 10-20cm for Friday. The snow along the length of the front is anticipated to remain fairly moderate, but it may end up being patchy, resulting in some areas seeing breaks in the snowfall. Despite this, a widespread 5-10cm is expected to fall across Alberta and Saskatchewan.

Saturday

The cold air will wrap around the backside of this storm and that will become noticeable starting in Alberta Saturday morning. The snow will continue in parts of all three Prairie provinces throughout the day Saturday and we’ll have more details of how much to expect in the forecast we will post tomorrow.

Arctic Blast Across Canada With Potentially Coldest Air in Years; Dangerous Wind Chills Near -40°C Possible Next Week

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Get ready for a major Arctic chill as some of the coldest air in over a year is set to spread across much of Canada over the next week.

This icy blast will originate in the Arctic and surge into Central and Eastern Canada, causing temperatures to plummet to dangerously low levels. Wind chills could drop to between -30°C and -40°C—or even lower—in several regions by early next week.

This extensive polar plunge will impact much of Canada and even stretch into parts of the United States. Over the next five to seven days, nearly everyone will feel the chill in some capacity.

The Prairies will be the first to experience this frigid air as it arrives late Friday into Saturday. By early next week, the cold will spread eastward into Ontario, Quebec, and Atlantic Canada, blanketing nearly all of the country in sub-zero temperatures. The cold snap is expected to last for a few days, but relief will arrive with more seasonal air by mid to late next week.

SATURDAY

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

In Alberta, Saskatchewan, and Manitoba, the cold will start to settle in Friday night and intensify into Saturday morning. Temperatures will plunge below -20°C and could approach -30°C in some areas, even before factoring in the wind chill.

The coldest conditions will hit northern areas like Fort McMurray and Thompson, where wind chills could make it feel like -40°C to -45°C.

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Most of Saskatchewan and Manitoba, excluding Winnipeg, will see wind chills between -35°C and -40°C. Winnipeg and Edmonton will feel slightly less severe, with wind chills in the low to mid -30s, while Calgary will range from -25°C to -30°C.

Northern Ontario will also begin to feel the chill, with wind chills making it feel close to -30°C in places like Thunder Bay by Saturday morning.

Meanwhile, Southern Ontario will enjoy one last relatively mild day on Saturday, with temperatures near the freezing mark. However, the arrival of the Arctic air could bring a flash freeze late Saturday in Northeastern and Southern Ontario. Rapidly dropping temperatures may lead to icy road conditions, so caution is advised.

SUNDAY

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

By Sunday morning, the cold air will deepen across the Prairies, bringing wind chills into the -40s for much of Saskatchewan and Manitoba. This includes locations like Edmonton, Fort McMurray, Saskatoon, Regina, and Thompson.

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Winnipeg and Calgary will be slightly less frigid, with wind chills closer to -30°C to -35°C, though colder temperatures are expected by Monday morning.

Ontario will also see temperatures drop sharply by Sunday morning. Northern Ontario will experience bitterly cold air, with actual temperatures between -20°C and -30°C and wind chills closer to -40°C in the northernmost areas.

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Southern Ontario will see temperatures ranging from -10°C to -20°C, with the coldest air in Central and Eastern Ontario. Wind chills in Northern sections of Southern Ontario could approach -30°C, while Southwestern Ontario and the Golden Horseshoe will feel like -20°C to -25°C.

The arrival of Arctic air could also reignite lake-effect snow squalls early next week. Snowbelt regions around Lake Superior, Lake Huron, and Georgian Bay could see heavy snowfall as a result. More details on this will be provided in a separate forecast.

STAYING SAFE IN THE EXTREME COLD

(Forecast continues below)

Extreme cold can pose significant risks to safety and health, especially when wind chill intensifies the freezing temperatures. Even moderate wind speeds can dramatically lower the "feels like" temperature, increasing the risk of frostbite.

When wind chill drops below -27°C, exposed skin can freeze in 30 minutes or less. At extreme levels, such as -40°C or colder, frostbite can occur in as little as 5-10 minutes.

To protect yourself and your loved ones, limit time spent outdoors during these dangerous conditions. If you must go outside, dress in multiple layers of loose-fitting, insulated clothing.

Make sure to cover all exposed skin with hats, scarves, gloves, and insulated boots. A windproof outer layer is essential to reduce the effects of cold winds.

Pay attention to frostbite warning signs, including numbness, tingling, or a loss of colour in fingers, toes, nose, or ears. If you suspect frostbite, immediately move to a warm location and avoid rubbing the affected area, as this can worsen tissue damage.

Hypothermia is another serious concern; symptoms include shivering, confusion, and slurred speech. Seek medical attention if hypothermia or frostbite is suspected.

For those driving during extreme cold, always keep an emergency kit in your vehicle with essentials such as blankets, extra clothing, food, and water.

Ensure your phone is fully charged, and let someone know your travel plans. Avoid leaving pets outdoors for extended periods, as they are equally susceptible to frostbite and hypothermia.

MONDAY

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The worst of the cold will likely occur Monday morning, especially in the west, with Arctic air entrenched across much of Central and Eastern Canada. Temperatures near or below -30°C will stretch from Alberta to Western Quebec.

Wind chills could make it feel like -40°C or colder across Saskatchewan, Manitoba, Northern Ontario, and parts of Eastern Alberta and Western Quebec. Calgary and Edmonton will escape the worst, but wind chills will still hover around -35°C.

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

In Southern Ontario, most areas will see temperatures near -20°C, with Central and Southwestern Ontario experiencing the coldest air. Wind chills will make it feel like -25°C to -35°C, a pattern also expected in Montreal and Quebec City.

Atlantic Canada will begin to feel the polar plunge by Monday morning. Wind chills will drop to around -25°C in Northern New Brunswick, while Prince Edward Island and Nova Scotia will remain slightly milder, with wind chills ranging from -5°C to -15°C.

TUESDAY

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

By Tuesday morning, the coldest air will shift further east, bringing some relief to the Prairies. Alberta will see temperatures climb back into the single digits, with wind chills in the teens.

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Eastern Saskatchewan will remain colder, with wind chills near -25°C to -30°C, while western regions warm slightly. Manitoba will also improve, though wind chills will still range from -30°C to -35°C, particularly near the Ontario border.

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Tuesday is likely to be the coldest day for Ontario, as the Arctic air peaks over the province. Northern Ontario will see temperatures between -30°C and -40°C, with wind chills plunging well into the -40s.

Southern Ontario will experience temperatures from -20°C to -30°C, with wind chills making it feel like -35°C to -40°C in Central Ontario and the Ottawa Valley, and -30°C to -35°C elsewhere.

Montreal and Quebec City will endure similarly bitter conditions, with wind chills of -35°C or lower. Central and Western Quebec will feel even colder, with wind chills dropping below -40°C.

Atlantic Canada will also face its coldest morning on Tuesday. Wind chills will range from -35°C in Northern New Brunswick to the -20s in Nova Scotia and Prince Edward Island.

WEDNESDAY

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Wednesday morning will bring one final bitterly cold start for much of Eastern Canada, but signs of improvement will begin to appear.

Southwestern Ontario, including Windsor, Sarnia, and London, could see wind chills near -35°C or even -40°C. Northern Ontario will finally climb above -30°C wind chills for the first time in days, marking the beginning of a warming trend.

Quebec will remain very cold, with wind chills near -40°C in some areas, while Montreal and Quebec City will continue to see wind chills of -35°C.

Atlantic Canada will face another cold morning, with wind chills between -20°C and -35°C.

Most of Eastern Canada will see a reprieve from the extreme cold by Thursday morning. However, this may only be temporary, as long-range models suggest another Arctic surge could arrive late next week into the weekend. Stay tuned for updates.

A Brief Skiff of Snow Expected Across Parts of Southern Alberta & Saskatchewan for the First Weekend of the New Year

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

It’s been fairly quiet across the Prairies for the past few weeks and that trend has continued so far in the beginning of the new year. As we approach the first weekend of the year, there’s enough snow expected for parts of Southern Alberta and Saskatchewan over the next 24 hours to warrant a forecast.

The snow will begin to fall along the American border in Alberta early this evening and it will gradually spread north and eastward overnight and early Saturday morning. It is only going to reach as far north as Calgary and into Southwest Saskatchewan before the system starts to fall apart before sunrise Saturday morning. The snow will gradually taper off throughout the morning and into the early afternoon.

The snow is expected to be light throughout the duration of the event, leading to most of the area receiving 5-10cm of accumulation. As the system falls apart Saturday morning, the snow is expected to linger over parts of Southeast Alberta and Southwest Saskatchewan, resulting in over 10cm of snowfall here.

A White Christmas is in the Forecast for Most of the Prairies, Odds are Not Good in Southern Alberta

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The second half of November and all through December have been marked by a series of snowstorms and periods of frigid temperatures across the Prairies. With Christmas only four days away, the odds of a White Christmas are becoming clearer.

According to Environment Canada, in order for an area to have a White Christmas, there needs to be at least 2cm of snow on the ground as of 7am on Christmas Day. This is typically an easy threshold to cross in the Prairies and it appears that this year will be no different for most, but not all.

Currently, the snowpack is considerable across the Prairies, at least 10cm deep across a majority of the regions and large swatch where the snow is over 20cm in all three provinces. There are a few pockets where this is the exception, particularly in Southern Alberta where warm temperatures early in the week have resulting in little to no snow on the ground. Looking ahead over the next few days, some warmer air and a mix of rain and freezing rain will decrease the likelihood of a White Christmas for some.

Modelled Snow depths as of Saturday, December 21st at 6am CT.

Manitoba

Northern Manitoba may see some scattered flurries this evening and overnight and again Tuesday morning. Otherwise, there is no other fresh snow expected between now and Wednesday morning. Temperatures will remain below freezing across the province until Christmas morning so no melting of the existing snow is expected. As a result, all of Manitoba can expect a White Christmas.

Saskatchewan

Like Manitoba, Northern Saskatchewan may see scattered flurries over the next few days, but no significant snowfall is expected. There is, however, a threat to White Christmas chances in Southwest Saskatchewan.

Early Sunday morning, temperatures in this area will climb to above freezing and will stay there throughout most of the day. Not only will this melt some of the limited snowpack in the area, a mix of rain and freezing rain will also result in melting. Temperatures are expected to rise once again on both Monday and Tuesday. With no additional snow in the forecast, a White Christmas can not be guaranteed in this area, but it is not completely ruled out.

Alberta

The chances for a White Christmas will vary across Alberta. A large part of Southern Alberta already has less than 5cm of snow on the ground and daily highs in the single digits between now and Christmas significantly impact the chances of a White Christmas here. The relative warmth will also stretch northward, just east of the Rockies over the coming days, but the greater snowpack and temperatures only reaching a degree or two above freezing will keep the hopes for a White Christmas alive.

The only fresh snow in the forecast for the province will be isolated to the Mountains and far Northern Alberta. There’s the chance for some rain to cross through Southern Alberta overnight and through Sunday morning which will further hinder the likelihood of a White Christmas in the area.

Please keep in mind that this is just a preliminary forecast and is based on current data. The forecast will be updated over the coming days, with the final forecast set to be posted on Christmas Eve. Make sure to stay tuned!

Winter Storm Could Dump Over 20cm of Snow on Parts of the Prairies Starting Wednesday

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The latest winter storm set to impact the Prairies will bring heavy snow across a wide stretch of the region, from Grande Prairie into Southwestern Manitoba, over the next two days. The storm will also bring strong wind gusts, particularly in Southern Alberta, and the threat of mixed precipitation in Southwestern Saskatchewan.

Alberta

The storm will cross into Alberta through the Rockies early Wednesday morning. The snow will chart a continuous path as it pushes through the Rockies in the north, however to the south it will start to develop further east of the Mountains and while a few centimetres may fall, it will essentially skip over parts of Southern Alberta, including Calgary.

By around sunrise, the snow will spread across Central Alberta and into the Southeast corner of the province, where it will sit throughout the afternoon. The snow will be heavy at times, falling at up to 2cm per hour, which will lead to a widespread 10-20cm of snow falling by the end of the day from Grande Prairie, southeastward through Edmonton, and beyond the Saskatchewan border.

The snow will start to taper off from west to east in the late afternoon as the storm continues to track eastward and eventually ending in the evening, aside from some lingering scattered flurries.

There will be some strong wind gusts associated with this storm, up to 100km/h, but they are expected to be mostly isolated to the Southern Rockies and the Foothills, away from the heavy snow. Gusts of 40-60km/h are likely across the rest of Southern Alberta so blowing snow may be a concern, especially closer to the Saskatchewan border.

Saskatchewan

The leading edge of the snow will push its way into Southwestern Saskatchewan before sunrise Wednesday and it will spread eastward into the province through the morning and early afternoon. At that point, the band of snow will remain relatively stationary for several hours. It will also intensify over parts of Southern and Central Saskatchewan, leading to snowfall rates up 3cm per hour that will result in an area from Kindersley to Estevan seeing over 20cm of snow. Outside of this swath of the heaviest snow, much of the southern half of Saskatchewan can expect at least 5cm of fresh snow.

In the early afternoon, as the backside of the band of snow crosses into the province, some warm air will push in from the south. Temperatures on the ground will remain below freezing, but it will be warm enough aloft to result in freezing rain and/or ice pellets in Southwest Saskatchewan through the afternoon and into the evening.

The wind will also be a concern across Southern Saskatchewan and could result in reduced visibility due to blowing snow in the evening as gusts approach 80km/h. These conditions could very likely lead to highway closures across the region so keep that in mind when travelling in the area. The snow will start to make its way out of Saskatchewan in the evening and gradually diminishing across the province overnight and into the morning.

Manitoba

The storm will reach Manitoba by Wednesday evening, with snow starting in the Westman Region and extending deeper into the province through the rest of the evening and overnight.

Given the storm’s overall southeastward trajectory, the Southwestern portion of Manitoba can expect to be the most impacted. The snow will remain steady across this area overnight and into the morning, resulting in 5-20cm of snowfall. The greatest snowfall is expected in the southwest corner of the province and includes Boissevain, Killarney, and Virden. During the morning, the snow will start to spread further eastward towards the Ontario border, briefly bringing some light snow into the Winnipeg area before the storm completely exists the region by the lunch hour.

What previously looked like a possible widespread ice event, according to weather models, has luckily down-scaled and will now only impact a narrow track across parts of Saskatchewan and Manitoba.

A disorganized system will cross into Southeast Saskatchewan from Montana after midnight tonight, travelling northeastward and reaching Manitoba shortly before sunrise. This system will only bring a narrow band of precipitation to the region, but due to the presence of warm air aloft and below freezing temperatures at the surface, this precipitation will fall as freezing rain. The freezing rain will be light and last for several hours, resulting in ice accretion amounts up to 5mm.

Temperature Profiles and Precipitation Types

By around the lunch hour, the freezing rain will start to taper off and transition over to snow. As the entire system pushes eastward, Southern Manitoba will also start to see some snow moving in from North Dakota Sunday afternoon. The system will become more organized throughout the evening and overnight, leading to the development of additional snow in Central and parts of Northern Manitoba. There is still some uncertainty regarding exact snowfall amounts, but it looks like the southern half of the province can expect 5-15cm of fresh snow by the end of Monday.

Widespread Temperatures Below -30°C and Windchills Approaching -45°C Have Prompted More Extreme Cold Warnings

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The extreme cold continues across Saskatchewan and Manitoba overnight tonight and through to tomorrow morning. Unfortunately, it will be colder than this morning, and a much larger area can expect temperatures below -30°C to settle in after midnight and continue until the late morning.

This intense cold poses a risk to everyone, especially young children, the elderly, individuals with chronic illnesses, outdoor workers, and those without adequate shelter. Symptoms of cold exposure, such as shortness of breath, chest pain, muscle pain and weakness, numbness, and colour change in fingers and toes, should be monitored closely.

The winds are expected be light again, at around 10-15km/h, as the temperatures reach their lowest point. With the even colder air than this morning, these light winds are going to result in windchills that are approaching -45°C. The coldest windchills are expected in the Westman Region, but windchills below -40°C will still be felt over a significant area. As a result, Environment Canada has issued more widespread Extreme Cold Warnings than last night, stretching from Saskatoon and into Northern Ontario.

At these temperatures, frostbite can occur in as little as 30 minutes, and in some areas close to 10 minutes, so it is crucial to cover up when going out and limiting exposure all together. It’s also wise to keep emergency supplies in your vehicle, including extra blankets and jumper cables, in case of an emergency.

Extreme Cold Makes Its First Appearance of December With Windchills Dipping Below -40°C

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The extreme cold has returned to the Prairies with temperatures dipping below -20°C across a majority of Saskatchewan and Manitoba, with the exception of the Southwest Corner of Saskatchewan. Temperatures will be lower than -30°C in parts of Central Saskatchewan and into the Parkland Region of Manitoba. The cold Arctic air pushed south throughout the day today and temperatures will continue to fall overnight before reaching their lowest point in the mid-morning.

This intense cold poses a risk to everyone, especially young children, the elderly, individuals with chronic illnesses, outdoor workers, and those without adequate shelter. Symptoms of cold exposure, such as shortness of breath, chest pain, muscle pain and weakness, numbness, and colour change in fingers and toes, should be monitored closely.

Winds overnight tonight are expected be light, at around 10-15km/h. These light winds will easily push the windchill below -40°C, which has prompted Environment Canada to issue Extreme Cold Warnings for parts of both provinces.

At these temperatures, frostbite can occur in as little as 30 minutes so it is crucial to cover up when going out and limiting exposure all together. It’s also wise to keep emergency supplies in your vehicle, including extra blankets and jumper cables, in case of an emergency.

Messy Weekend Clipper Expected to Bring Widespread 10-20cm of Snow and Risk of Freezing Rain to the Prairies

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

It’s going to be a messy weekend across the Prairies with a Clipper expected to bring over 10cm of snow in a swath from Edmonton, through Saskatoon, to Winnipeg. This will be the first considerable snowfall of the season for the Winnipeg area, which has lagged behind the rest of the Prairie provinces by a couple of weeks.

The snow won’t be the only concern from this storm; there will be the risk of freezing rain across the region in pockets where temperatures will climb a degree or two above freezing. On top of the snow and freezing rain, some areas will also see rain from this storm, making for a mixed bag of a weekend!

Alberta

Our Clipper will start to make its way into Alberta in the Northern Rockies as a disorganized mess of rain, snow, and mixed precipitation mid-morning Saturday. Temperatures are expected to climb above freezing across much of Southern and Central Alberta so as the system pushes eastward into the province through the afternoon, the precipitation should fall as rain.

Things become much more organized in the evening and as temperatures start to fall, most of the rain in Central Alberta will switch over to snow. There will be the risk of brief freezing rain during this transition which could make surfaces quite icy before being covered with snow. With the organization of the storm, snowfall rates will increase and snow accumulations above 10cm should start around Edmonton and continue east-southeastward along the track of the storm.

As the system starts to exit the province early Sunday morning, some precipitation will actually push into Southern Alberta. There will be brief freezing rain along the leading edge, bringing trace ice accretion to Red Deer and eastward, followed by some moderate snowfall that will lead to 5-10cm of snow to the area, including Medicine Hat. The snow will taper off in the west through Sunday morning, but it is expected to linger in the east through the day.

Saskatchewan

The storm will extend into Saskatchewan starting in the late afternoon or early evening on Saturday. With the temperatures in the single digits, it will start off as a narrow band of rain. As the temperatures fall later in the evening, however, we expect there to be a transition over to freezing rain that will last for several hours as the storm continues its path southeastward. There could be a considerable track of ice accretion of 2-5mm that stretches from Saskatoon through Moosomin and into Southwest Manitoba.

Unfortunately, the freezing rain will eventually transition to snow from west to east overnight, which will cover the frozen ground, making things even more slippery. This snow will be moderate to heavy at times, with snowfall rates up to 2cm per hour, resulting in snowfall totals of 10-20cm over a wide stretch of the province.

During early morning hours of Sunday, snow will start to wrap around from the west, bringing 5-10cm of snow to Southwest and West Central Saskatchewan and lesser amounts along the International border. The snow will start to dissipate Sunday afternoon before ending Monday morning in the southeast corner of the province.

Manitoba

In a similar fashion to what is expected in Saskatchewan, as the Clipper crosses into Manitoba overnight Saturday, the leading edge will bring freezing rain into the province. This is only expected in the southwest corner of the province and the greatest ice accretion of 2-5mm will be found in an area that includes Virden and Boissevain.

After a few hours of freezing rain, the snow will follow and spread eastward across Manitoba through the morning. The storm will grow in size as the snow wraps around from the west in the early morning and the arrival of heavier snow in the afternoon will lead to a wider area receiving 10-20cm. The storm will start to push into Northern Ontario early Sunday afternoon and the snow will start to taper off overnight before eventually exiting the region by early Monday afternoon.

Widespread wind gusts of 50-70km/h are expected with the Clipper so on top of surfaces being quite icy over a wide area, blowing snow will be a concern As a result, we may see some highway closures throughout the duration of the storm. Road conditions will likely be very poor in the hardest hit areas so please take extra caution when travelling this weekend!

Another Night of Extreme Cold on Tap, Warnings Extend into Manitoba for Tonight as Windchills Reach -40°C Over a Wider Area

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The extreme cold continues across the Prairies with overnight lows dipping below -20°C across a large part of the region and lower than -30°C in Central Saskatchewan once again tonight and into tomorrow morning.

This intense cold poses a risk to everyone, especially young children, the elderly, individuals with chronic illnesses, outdoor workers, and those without adequate shelter. Symptoms of cold exposure, such as shortness of breath, chest pain, muscle pain and weakness, numbness, and colour change in fingers and toes, should be monitored closely.

Winds overnight tonight are expected to remain similar to last night, peaking at around 10-15km/h, but they are expected to be more widespread. These light winds will easily push the windchill below -40°C over a larger area, resulting in Environment Canada issuing more Extreme Cold Warnings for tonight.

At these temperatures, frostbite can occur in as little as 30 minutes so it is crucial to cover up when going out and limiting exposure all together. It’s also wise to keep emergency supplies in your vehicle, including extra blankets and jumper cables, in case of an emergency.

It appears that Saskatchewan and Manitoba could see a bit of a reprieve tomorrow night, with the coldest air expected to be found in Alberta instead.

First Extreme Cold Air of the Season to Settle Across the Prairies Over the Coming Days, Overnight Lows Dipping Below -30°C

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

While it has been quite cool across the Prairies this week on the backside of last weekend’s storm, it’s about to get even colder over the next few days. The first of this extreme cold will be experienced overnight Thursday and Friday morning. A large swath of the Prairies will have overnight lows below -20°C tonight while parts of Central Saskatchewan will see temperatures dipping below -30°C, prompting the first Extreme Cold Warnings of the season from Environment Canada that includes Saskatoon.

This intense cold poses a risk to everyone, especially young children, the elderly, individuals with chronic illnesses, outdoor workers, and those without adequate shelter. Symptoms of cold exposure, such as shortness of breath, chest pain, muscle pain and weakness, numbness, and colour change in fingers and toes, should be monitored closely.

Winds overnight are expected to top out at around 10-15km/h and while this is just a light breeze, it’ll be enough to drive the windchill well below -40°C in the coldest areas. At these temperatures, frostbite can occur in as little as 30 minutes so it is crucial to cover up when going out and limiting exposure all together. It’s also wise to keep emergency supplies in your vehicle, including extra blankets and jumper cables, in case of an emergency.

We will continue to provide updates over the coming days as these cold temperatures persist.

Second Storm This Week Will Dump Even More Snow Across Saskatchewan & Manitoba This Weekend

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

We hope you’ve kept your shovels handy following the storm earlier this week because there is even more snow on its way for Saskatchewan and Manitoba this weekend.

Thankfully this storm will be less complex than the previous one and the situation in two particular areas will be different this time around. The western edge of Saskatchewan, where next to no snow fell during the previous storm, is now in the crosshairs with more than 20cm of snow expected. Meanwhile, those in Winnipeg and the Eastman Region, who received drenching rains within the warm sector of the earlier storm, will finally see some snow, but overall accumulations will be limited.

Since last night’s preliminary forecast, model data has trended slightly to the north. This means that areas along the boundaries from the previous forecast could see either an increase or decrease in projected snowfall totals.

We’ve already seen a bit of light snow pushing its way into Southwest Saskatchewan from Alberta this afternoon and while this snowfall is associated with the expected storm, its a precursor band that will bring less than 5cm of snow to a small area that includes Maple Creek and Shaunavon.

The main event will begin Saturday morning, as the more organized band of snow pushes into Saskatchewan. It will start as light snow, but gradually intensify through the late morning and continuing overnight as the storm makes its way across the province. The heaviest snow is expected to fall mostly in Western Saskatchewan, leading to over 20cm of accumulation from Kindersley to Wynard by Sunday morning. At that point, there will only be some lingering light snow in Northern Saskatchewan that will continue into Monday morning.

The snow will remain steady as it crosses into Manitoba starting Saturday evening in the Westman Region and then the Parkland Region around midnight. The storm will begin to lose intensity by the time it moves into the Interlake Region on Sunday morning and as a result, there will be a decrease in snow accumulation down to 5-10cm, with only light snow falling for the remainder of the day. Since the storm will have a slight northeasterly trajectory as it crosses Manitoba, communities along the American border and into Winnipeg will see less than 5cm of snow fall.

The snow will begin to taper off Monday morning across Manitoba, with some scattered flurries continuing until late in the day, at which time the storm will exit the region.

One of the biggest challenges during the last storm was the blowing snow due to high winds. While the winds are not expected to be quite as intense this time around, gusts up to 50km/h could reduce visibility and result in some road closures, particularly through Southern Saskatchewan.

Another Snowstorm Could Dump Up to 30cm of Snow on Saskatchewan & Manitoba This Weekend

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

As residents across parts of Saskatchewan and Manitoba begin digging out from the first significant snowfall of the season, another winter storm is already on the horizon.

Snowfall is expected to start in western Saskatchewan as early as Saturday morning, with the worst conditions anticipated over the weekend. By the time the system wraps up on Monday, widespread snow accumulation of 15 to 30 cm is likely.

Although current model data shows good consistency regarding the storm's intensity and track, it’s still over 24 hours away, and some slight adjustments are possible. Be sure to check back on Friday for our updated forecast, which will include more precise snowfall accumulation predictions.

A teaser of what’s to come will arrive on Friday as light snow begins moving into southwestern Saskatchewan during the afternoon. This snowfall isn’t expected to spread far across the province and should mostly fizzle out by Saturday morning. Areas like Maple Creek and Shaunavon could see a few centimeters of accumulation, possibly up to 5 cm.

However, the break in snowfall will be brief, as another wave of precipitation sweeps into the province from Alberta. This system will begin as light snow late Saturday morning, gradually increasing in intensity throughout the afternoon.

By the evening, snowfall will have reached Saskatoon and Regina, with moderate to heavy snow spreading across much of Saskatchewan. The worst conditions are expected overnight into Sunday morning, when snowfall rates will peak.

Blowing snow could also pose a concern, with wind gusts of 40-50 km/h reducing visibility on roads. While conditions aren’t expected to meet blizzard criteria, drivers should anticipate poor travel conditions and potential highway closures beginning Saturday evening, particularly in western Saskatchewan. Road conditions will likely remain hazardous until Sunday afternoon, starting with improvements in the western parts of the province.

By the early hours of Sunday, snowfall will have reached western Manitoba, with its intensity ramping up through the morning. Current forecasts suggest the heaviest snowfall will target central portions of western Manitoba, including the Interlake region.

Brandon is expected to see snow begin late Sunday morning, with light to moderate snowfall continuing throughout the day. Winnipeg will likely see snow begin in the early afternoon, continuing into the evening and overnight hours.

Snowfall will gradually taper off by Monday morning, with lingering flurries in central parts of Saskatchewan and Manitoba.

The storm is expected to lose some intensity as it progresses eastward across the Prairies. This means the highest snowfall totals will likely occur in western and central Saskatchewan. Snowfall amounts of 20-30 cm are expected in these areas by Monday morning, with localized pockets exceeding 30 cm. Locations such as Swift Current, Moose Jaw, Regina, and Kindersley are within this high-impact zone.

For the rest of Saskatchewan, snowfall amounts are forecast to range between 5 and 15 cm, with some areas potentially nearing 20 cm depending on the storm’s exact track. We’ve opted for a general forecast of "up to 20 cm" for now but expect refinements in our final update.

In Manitoba, western regions—including areas already hit hard by the earlier storm this week—can expect 10-15 cm, with isolated totals approaching 20 cm. Areas east of Brandon, including Winnipeg, are forecast to see lighter accumulations of 5-10 cm. Snowfall totals will taper off further north, with minimal impacts expected in northern Manitoba.

ESTIMATED WIND CHILL ON SATURDAY MORNING - MAP FROM WEATHERBELL

One significant difference between this storm and the one earlier this week is the temperature. This event will be accompanied by much colder air, meaning it will produce all snow, with no risk of mixed precipitation. Additionally, colder temperatures will result in higher snowfall ratios, so it won’t take much liquid precipitation to produce substantial snowfall amounts.

This colder air also brings added risks for anyone traveling during the storm. Extremely cold wind chills are expected to develop as early as Saturday, with some areas feeling like the -20s across Saskatchewan and into Manitoba. If you get stranded on the roads, staying warm may be difficult, so it’s highly recommended to avoid travel during this storm.

First Major Winter Storm of the Year Will Bring Up to 50cm of Snow and Blizzard Conditions to Saskatchewan & Manitoba

/

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

The first major winter storm of the season for the Prairies is here, with rain already falling in Southeast Saskatchewan along with pockets of freezing rain and snow. In last night’s preliminary forecast, we discussed the complexity of this multi-day storm and now that the storm is on our doorstep, there is more confidence in the forecast. Some areas of Central and Northern Saskatchewan and into Northern Manitoba could now see upwards of 50cm by the end of Wednesday, with blizzard conditions possible in the south.

As mentioned above, the first round of precipitation from this event has already made its way into Saskatchewan this afternoon. Rain is falling in Southeast and East Central Saskatchewan and there is snow further north, in the Hudson Bay area. The rain will transition over to snow as we progress through the evening with the heaviest snow expected to fall east of Prince Albert, from Melfort through to Cumberland House, starting later in the evening and continuing straight through to Wednesday morning.

As this band of precipitation pushes eastward into Manitoba overnight and into the early morning hours of Tuesday, it will encounter a strong low pressure system coming north out of the States. This incoming system from the south will bring steady rain, that is heavy at times, to Southern Manitoba throughout Tuesday morning. When the two systems meet, they will merge to form one large storm and by late Tuesday morning, cooler air will be pulled towards the centre of the storm from Northern Saskatchewan, leading to a transition of rain to snow with a brief period of freezing rain in the Westman Region.

By Tuesday afternoon, the snow will start to ease in Saskatchewan, but snowfall rates in Manitoba, on the other hand, will increase, leading to quick accumulations of snow. It’s at this point that the winds will start to pick up. Sustained winds of 40km/h and gusts exceeding 70km/h, combined with the heavy snowfall, will likely lead to blowing snow and blizzard conditions overnight Tuesday through to Wednesday morning.

This storm will finally diminish Wednesday afternoon, leading to a gradual tapering off of snow throughout the region.
