Frigid air dominates most of Canada to end January
Arctic air remains entrenched across much of North America as January nears its end. Frigid conditions extend from the eastern Prairies to Atlantic Canada, with a deep trough settling over Ontario and Quebec.
Temperatures are well below seasonal norms this week.
Friday stands out in particular for its cold forecast: Winnipeg will sit near -20°C, Ontario and Quebec in the minus teens, including Toronto at -14°C, possibly its coldest day of the season so far.
Northern Ontario and Quebec will see lows dipping into the -20°C range.
The cold weather brings calmer conditions however, from the Prairies right through to Atlantic Canada during this extended deep freeze.
DON’T MISS: More than just bitter cold: The polar vortex can be quite beneficial
There are some signs of a pattern change beginning
The Arctic air currently gripping much of Canada is expected to shift eastward towards the Atlantic Coast, setting the stage for a potential East Coast storm. While forecast models remain uncertain, there is a possibility of a nor’easter impacting parts of the U.S. and Canadian East Coast late this weekend.
