11 PM Late Evening Update

Forecaster: James Follette

Good Evening! Another Storm system is on its way towards Atlantic Canada for the start of the new work week with Heavy soaking rains, Strong to Damaging Winds & yes, even some snow! with the potential for blowing snow and blizzard-like conditions.

Monday, November 23rd.

Rain will begin to spread into the Southern portions of the province early tomorrow morning from 7am in Yarmouth to 11am in Halifax and surrounding areas, This rain will be the first outer bands so it will be a light rainfall.

As we fast forward into the early evening hours, at around 5-5:30pm The rain will become more moderate over Eastern areas from Liverpool to Halifax, still fairly light through Digby & Yarmouth. Rain spreads into Northern Nova Scotia, almost entering Cape Breton.

By Late evening hours tomorrow, we will begin to see that heavier rain moves into the Southern portions from Yarmouth to Halifax by 8 pm and Light rainfall spread elsewhere in the province, a more moderate rainfall as you may notice by the amount of rain falling on the map from Halifax to Antigonish and New Glasgow, that is Moderate rainfall occurring.

Now at 11pm nearing Midnight, we see the Heavy rainfall continue in the South and spread North of the province, only Cape Breton seeing some Moderate rainfall.

Tuesday, November 24th

As we enter the early morning hours of Tuesday, The 2 systems will move a bit more quickly to taper off the showers and rain for Yarmouth and much of Shelburne, parts of Digby county as well. but light rain or showers will persist for Liverpool to Kentville and a more soaking rain for Halifax to New Glasgow and as far North as Sydney.

As many will wake up near 5 and 6am on Tuesday, the entire Southern portions will be dry and done with the rain and the rest of the system in fact! Few sprinkles in Halifax may linger and showers will persist into Truro and New Glasgow & Amherst with heavy rainfall persisting in Antigonish and Sydney.

As we get later into the morning hours, by 8 am the system begins to accelerate and much of the province would be out of the woods for any more rainfall, in fact, much of Nova Scotia with the exception of Cape Breton should have a fairly beautiful day Tuesday, despite the cold breezy winds that will stick around. Cape Breton will be seeing continued rainfall here at 8 am.

Monday Storm Timeline

Let’s now take a look at our storm timeline! We’ll start with the Southern portions first!

So in the Tri-Counties and South Shores, look for your rain to start very shortly this morning in the next few hours, between 7 and 8 am will be the first drops! and continue on to midnight.

For Mainland areas, New Glasgow, Halifax, Dartmouth, Greenwood & Kentville first drops falling near 10 or 11 am.

For Northern sections. Cheticamp and Sydney, your rain will not start until later this evening at around 8 pm. Cheticamp may see a brief period of flurries or light snow at 2 pm this afternoon from an onshore flow.

Tuesday Storm timeline

As we forward into Tuesday now! Rain will begin to end in the overnight hours by 2 or 3 am Tomorrow morning for much of everyone with exceptions to Greenwood and Kentville where your rain may linger into 5 AM.

The cold air will rush in here like racing horses at the track fighting each other for a win. This will send rain turning into the snow for Mainland and Northern sections. Halifax, Dartmouth you can see a brief period of snow from 8 am into 11 am tomorrow morning. Kentville can see quick brief snow at 8 am tomorrow morning.

Rain ends for Sydney at 10 am tomorrow morning, so for much of the province, by the time we get to mid-morning tomorrow, the storm is done with. In a way, it is, however, look at Cheticamp where the precipitation just keeps going for another 24 hours and changes to snow by 9 am and just persists into midnight. That is the back end flow of that storm taking advantage of that bitterly cold air above and just keep the snow and snow squalls persisting much of Tuesday.

Wednesday Storm Timeline

Now we are into Wednesday, Only place getting precipitation is Cheticamp and surrounding areas. Snow persists all way into early morning and ending by 6 am. So looking at a long period of snow from 9 am Tues to 6 am Wed. This will be the reason of the high snowfall amounts for this area.

Rainfall Amounts through Tuesday

Now looking at the Rainfall amounts we can expect through out Tuesday. Much of province looking to see 20-30 mm with local areas likely to receive 40 mm, Greenwood, Kentville, New Glasgow, Sydney you will all see a bit less rainfall with amounts of 10-20 mm with local amounts up to 30 mm. Then finally for Western Cape Breton.. going to be hardest hit area with up to 50 mm of rain and potential local amounts up to 70mm, and perhaps even a bit higher than that! this is before the change over to snow!

Ugh! Snowfall Amounts!

If there is any good news in this forecast, is that not everyone will see snow! Some Flurries are expected through parts of Digby and Kentville and then a widespread path of snowfall from Amherst to Antigonish and Sydney and these areas will see amounts of only up to 2cm! maybe some local amounts up to 4cm.

But the heaviest snow is Western Cape Breton! where the snow will fall for a very long period of time, into Wednesday morning. amounts of up to 6cm, some local amounts up to 10 cm.

The snow is not the bad part… it’s the wind! We are looking at very strong to damaging winds in Cape Breton along with Les Suetes! This combined with a long period of snow, at times heavy will create blizzard-like conditions!

The big bad wolf's breath… Blowing very hard! May cause some damage!

Finally last but not least! the winds! Winds will Gust pretty strong across the province, but Northern parts will see the really big winds where you can see some power outages and damage to roofs, shingles, windows, property, Christmas Decor.

Much of province will see a good gusty wind of 70 to 80 km/h this includes from Yarmouth all way up to Halifax and near Antigonish.

Amherst, New Glasgow, Antigonish… you make it up to level 4! ;) congrats! that means you get to see winds from 80 to 95 km/h.

Majority of Cape Breton with the exception of Western Cape Breton… Level 5, is where you get to see the beginning of some slight wind damage. Gusts of 90 to 105 km/h.

And Western Cape Breton, this is the jackpot! Level 6 on our Wind Guage chart! Wind Gusts exceeding 100 to 115 km/h! This is where you will see nasty blizzard conditions, Blowing snow, windswept rain, large waves, power outages, and property wind damage.
