Extreme Cold Returns to Prairie Provinces

It's been a fairly mild weather across Canada this winter, but it's certainly not over. A few days of cold temperatures and extreme cold are set to return to the Prairie Provinces thanks to an Alberta Clipper (thanks a lot Alberta).

Combined with the northerly winds, wind chill values could approach -40 on Wednesday morning (see below).

Environment Canada has issued a Special Weather Statement ahead of this Clipper:

More winter weather on the way this coming week. The unseasonably mild weather that has distinguished so much of this February will give way to active winter weather beginning Sunday night. An intense, fast moving Alberta clipper system is forecast to develop Sunday night and cross the Prairies on Monday. So far, southern Saskatchewan and most of southern Manitoba look to avoid the heavier snow forecast to the north. Even so, a wintery mix of lighter precipitation including freezing rain will be possible Sunday night and Monday morning. Notably, while daytime highs later on Monday will be well above the freezing mark for some, temperatures will plummet rapidly once the clipper passes by. Strong northerly winds gusting 70 km/h will develop in the wake of the system, and morning low temperatures on Tuesday will be closing in on the -20 degree Celsius mark along with wind chill values in the -30 to -35 range. The bitter cold looks to last a couple days before moderating later in the week. Additional warnings and advisories may be issued, as necessary, as the event approaches.
