Cold Air Swallowing up Much of Canada

February 27, 2014; 3:54 PM ET

Cold, Arctic air will dominate across a large portion of Canada through the weekend.

The image below shows the projected temperature anomalies for early Sunday in degrees F from the GFS model ensembles.

The exceptions will be right along the Pacific coast and from Nova Scotia to Newfoundland where it will be more typical late February/early March cold if that makes you feel any better.

In case you did not hear, there was a massive pile-up earlier this morning along the 400 just south of Barrie, Ontario.

A large snow squall suddenly moved in and dropped visibility to almost zero in heavy snow that quickly accumulated on the road.

You can see the result below. Luckily, there were no life-threatening injuries from what I have heard as of Thursday afternoon.

Thoughts into next week....

1. Combination of weak storm and Arctic front will bring a general 2-8 cm of snow to Ontario and Quebec Friday night into Saturday night.

2. A second, southern branch system will track toward the Middle Atlantic region of the U.S. Sunday into Monday and the northern fringe of that system may brush extreme southern Ontario with some additional snow Sunday and perhaps Nova Scotia later Monday.

3. Potential for more accumulating snow over Vancouver Island and into the Vancouver, BC, area Sunday into Monday. Too early to have a good idea on accumulations but potential is certainly there for significant accumulations. I will keep you posted.

4. Brutal cold, especially this weekend, will be centered over the Prairies. Check out the projected low temperatures (sub minus 40 C readings) from the GFS model for Friday night/Saturday morning in degrees C. These are not wind chills.
