Extreme cold ahead for Prairies

Updated: Jan 23, 2021

Well it's that time of year...where you just don't want to go outside! An Alberta Clipper will quickly sweep through the Prairie Provinces over the next 24hrs, bringing with it extremely cold air from the Arctic in its wake. Below you can see the Clipper moving through the forecast area.

The contrast between Saturday and Sunday for parts of Saskatchewan and Manitoba will be quite impressive with a 20C difference between NW Ontario and Saskatchewan (see below).

Temperatures across most of Saskatchewan will have no issues reaching the low to mid -30C mark with wind chills approaching or surpassing -40 on Sunday morning. Southern Manitoba will be a bit more moderate, with temperatures in the -25C to -30C range. Below is a blend between different models, showing a good consensus of extremely cold temperatures on Sunday morning.

Below is a map from Weatherlogics, showing road conditions and air temperature on Monday morning at Yorkton in Saskatchewan, which forecast's a -31.9C temperature.

The pesky high pressure responsible for this cold spell should move out of the area and into Northern Ontario by mid-week, bringing more moderate temperatures back to the Prairies.
