Across the country, Canadians are turning up the thermostat as frigid temperatures and snow squalls creep in.

According to Environment and Climate Change Canada, as of Thursday morning there were extreme cold or winter storm warnings active from coast to coast, with the harshest extreme cold warnings stretching from northern Alberta all the way to Nova Scotia.

Regions of British Columbia are expecting significant snowfall, with Peace River set to receive 25-50 centimetres by Saturday morning.

In Fort McMurray, Alta., the wind chill will make the air feel like -40 degrees Celsius by Thursday afternoon.

On the other side of the country, residents of Halifax are bracing for an arctic airmass to strike on Friday, bringing with it a windchill value of -35 to -42 C, according to Environment Canada.

A map of alerts and warnings on the agency’s website shows a wide band of red warnings stretching from B.C. to the Atlantic provinces. There are warnings in place across all of New Brunswick, Prince Edward Island and Nova Scotia, with the vast majority of Manitoba, Quebec and Ontario covered in winter warnings as well.

This cold snap is in part due to a wave of cold from the Arctic’s polar vortex descending on Eastern Canada between Thursday night and Friday, according to climatologists.

“We’ll see temperatures that are really, brutally cold,” Environment Canada senior climatologist David Phillips told CTVNews.ca earlier this week. “It’s really a one-and-a-half-day wonder.”

COLD COMING FOR EASTERN CANADA

In New Brunswick, extreme cold warnings project that by Friday it will feel like -35 C to -45 C, lasting into Saturday morning.

The frigid conditions are predicted to clear up in all Maritime provinces sometime on Saturday or by Sunday morning, depending on the region, according to Environment Canada.

A storm off of the coast of Labrador is set to complicate things, bringing gusts of wind reaching up to 50 kilometres per hour to 80 km/h Friday night and into Saturday afternoon.
