A Colorado Low is on course to impact Southern Saskatchewan and Manitoba as the week draws to a close, promising significant snowfall and challenging weather conditions across the regions.

The journey of the Colorado Low northwards brings the first round of snow to Saskatchewan from the south, beginning overnight Tuesday and carrying on into Wednesday morning. The main band of snow is expected to catch up by late Wednesday morning. Along the American border in the southeast of the province, there may be a bit of mixing due to slightly warmer temperatures.

The snow is set to continue unabated through Thursday, beginning to dissipate from west to east Thursday afternoon and concluding entirely by the end of the day. The heaviest snowfall is anticipated in the Southwest and West Central regions, where a broad swath could see accumulations of 10-20cm. This 10-20cm zone also extends into Southeast Saskatchewan, covering a significant portion of the province with a hefty blanket of snow.

The influence of the Colorado Low extends into Manitoba by Wednesday evening, with snow initiating in the southwest and gradually expanding northward throughout the night. By Thursday morning, the snow could intensify, particularly in the Parkland and Westman Regions, where it may fall heavily at times. The storm is expected to exit the region late Friday evening.

A widespread accumulation of 10-20cm is forecasted across Southern Manitoba. However, in the Red River Valley and the Eastman Region, snowfall totals are predicted to be less than 10cm. This is due to mixing with rain as temperatures hover just above the freezing mark, limiting the accumulation of snow in these areas.

Nothing says January in the Prairies quite like negative double-digit temperatures and an Alberta Clipper bringing a healthy dumping of snow which is exactly what many can expect to see over the next couple of days.

The snow will start to make its way into Alberta from the Rockies shortly after midnight Tuesday and spread across Central and Southern Alberta through the morning hours.

The heaviest snowfall is expected to fall in Central Alberta, covering a swath from Grande Prairie and Grande Cache and through Edmonton to Wainright and Lloydminster.

This region, along with the Rockies, falls under the 10-15cm range for snowfall. Areas closer to the Rockies and in the Foothills can be expected to be closer to 15cm and potentially up to 20cm locally while Edmonton and eastward will be closer to 10cm. 

This will be a fairly short-lived event for Alberta with the hardest hit areas only receiving snow for a maximum of 12 hours and snowfall rates aren’t expected to be particularly high so overall accumulations will be limited. By early Wednesday morning, the snow will end for the province.

In Saskatchewan, the snowfall will begin to cross the border in the late morning and once again, the Central region of the province will be the hardest hit area with 10-15cm expected to fall.

This encompasses an area from Lloydminster and Kindersley, across Saskatoon and eastward to Hudson Bay and Yorkton. Wednesday morning will see the system stall after it crosses the border with Manitoba and East Central Saskatchewan will likely be on the higher end of the 10-15cm range along with the possibility of higher snowfall totals locally by the time the snow ends overnight Wednesday into early Thursday.

After finally crossing the border into Manitoba, the system will once again stall over Southwestern Manitoba. At this point, there is some disagreement between weather models regarding exactly how much snow this region can expect and a slight change in speed or trajectory could make a big difference in accumulation totals. As a result, we will be holding off on publishing a forecast until Tuesday evening.

A low-pressure system from Alberta has already begun making its way into Saskatchewan and towards Manitoba. Overnight tonight, snow and freezing rain will develop in Eastern Saskatchewan, and it will continue until late Sunday morning as the system continues to push eastwards.

In Manitoba, the precipitation will begin later, starting in the morning on Sunday and it is expected to continue throughout most of the day. Less than 5mm of ice accretion is expected, but a large part of Western Manitoba will be affected.

Snowfall amounts will be more widespread in Manitoba than in Saskatchewan with considerably higher totals. In particular, the Interlake Region and east of Lake Winnipeg could see over 10cm of snow by the end of the day Sunday.

Similar to Manitoba, total ice accretion in Saskatchewan will be less than 5mm, however, this will be enough to make surfaces slippery if left untreated and there is the potential for broken tree branches.

Snowfall amounts in Saskatchewan will mostly remain less than 5cm except for an area around Hudson Bay, where up to 10cm could fall. The freezing rain will fall further south of the snow and some areas may see a mix of both snow and freezing rain.

After a warm start to fall across much of the Prairies, conditions have begun to turn, with dropping temperatures dropping heralding the first significant snowfall of the season. 

The snow has already begun for Southern Alberta and into Southern Saskatchewan where it will continue overnight and throughout the day Tuesday. The heaviest snow, with totals of 10-20cm, is expected in the Rockies and eastward through Calgary and Lloydminster.

A secondary pocket of heavy snowfall is also possible in Southwestern Saskatchewan. Surrounding areas and Southern Manitoba can expect 5-10cm of snow by the end of the day Wednesday.

Following the snow, Arctic air will begin to settle into the region with overnight low temperatures in the negative double digits across much of Southern Alberta and Saskatchewan Tuesday into Wednesday and again the following night.
