A fierce snowstorm will approach the Canadian Border Sunday and linger until Tuesday across Saskatchewan and Manitoba: especially South-Central SK and MB.
A strong low pressure system originating from Colorado will move close to the aforementioned regions and intensify rapidly.
‘Colorado Lows’ are notorious for bringing intense blizzard conditions to the upper Dakotas and into the Prairies, however, they also pose a significant challenge to forecast as a slight directional change can alter the conditions dramatically.
Conditions will rapidly deteriorate Sunday PM, with heavy snow occurring in the time-frame of Sunday into Monday.
Blowing snow will be of considerable concern (through Tuesday), particularly for the South-Central SK/MB region.
Depending on the final track of the ‘Colorado Low’ some ice-pellets or freezing rain may certainly mix in, as the low may get pulled more Northeastwards bringing a slight warm sector, atmospherically, into several regions.

Significant snowfall to target a large swath near the SK/MB border where over 1 foot is likely. Higher elevations, although localized, could approach 2 feet.
Ice pellets and freezing rain are expected to mix with snow in Southern Manitoba and Southern Saskatchewan near the immediate Canadian/USA border, thereby limiting overall accumulations.
Dry air will also be plentiful in some regions of Southern Manitoba, therefore a few regions will likely ‘underachieve’ and may receive 10-15cm rather than 15-25cm.
Winnipeg will receive roughly 15cm of snow +/- 2-5cm. More snow will be present W and NW of the city.
It is important to remain vigilant in regards to this significant snowstorm, especially in what has been a relatively ‘quiet’ winter season across much the Prairies.
Please stay tuned, as we at TCW are monitoring this situation extremely attentively.
Drive safe and always be alert during winter conditions.
Avoid all unnecessary travel across heavily impacted regions as whiteout conditions will become inevitable.
