A strong surface low pressure and storm system is ahead this weekend for the Prairie Provinces. As is often common with these systems, cold air will funnel behind it and invade the Prairies with cold Arctic temperatures and wind chills for the following week.
Below shows the surface temperatures before, during and after the storm system.
After this system departs, a wave of cold temperatures and very cold wind chills will descend on the Prairies and last for the following week.
Expected Wind Chills Next Week
Below is a day-by-day expected wind chills for the Prairie Provinces. The loops show model trends, which means the way the model is trending in its outputs. Simply put, if you look at a specific area on the map and it does not vary much within this loop, then it is pretty safe to assume that is the wind chill you will see at that location. Ideally, you would look at multiple models this way and do a model blend to output a more accurate forecast.
