[GTranslate] -61 F: the lowest temperature in the country since 2017 was recorded on Sunday in Wekweeti, town of the Northwest Territories about 1,900 miles northwest of Toronto.

According to CTV News and Accuweather (click here: Temperature bottoms out at 61 below zero in northwestern Canadian town), due to the polar vortex, a fresh batch of Arctic air made its way into Canada this week, leaving some major Canadian cities battling subzero temperatures. Through early next week, this brutal cold will also infiltrate the United States and challenge numerous daily records.

Canada’s national weather service, Environment Canada, reported a reading of -51.9 C (or about -61 F) in Wekweeti of the Northwest Territories on Sunday, the lowest recorded temperature in the country since 2017, according to CTV News. Wekweeti is about 1,900 miles northwest of Toronto.

Temperatures across the entire country through this weekend could be below freezing, a difficult feat given the different climates from coastal locations to the Prairies.

On the West Coast, Vancouver, British Columbia, is forecast to hover near or below zero through Saturday night while on the East Coast, St. John’s, Newfoundland, is likely to stay in the 20s F through the middle of next week. In between, high temperatures from Edmonton, Alberta, to Winnipeg, Manitoba, may struggle to reach -10 F through the weekend.

“The Arctic air is not likely to stop in Canada as we move forward into next week. Temperatures will be dropping rapidly across portions of the United States through early Tuesday,” said AccuWeather Meteorologist Jake Sojda.
