Minus two, however, is not that far from normal. Your seasonal temperature around this time of year is -4 C for a daytime high,” Hasell mentioned.
“We’ll see a little bit more variability as the week goes on: colder-than-normal conditions kind of settling in starting on Friday,” she mentioned on Tuesday.
The purpose for the swings? Changing excessive and low-pressure methods.
Hasell mentioned sometimes with high-pressure methods — which trigger these crisp, clear, blue sky winter days Alberta is thought for — winds transfer clockwise, pulling frigid air down from the Arctic.
Conversely, Hasell mentioned low-pressure methods typically include air that strikes counterclockwise, drawing hotter circumstances from the south and west of the continent.
“Unfortunately, you’ve kind of been just on the edge of air masses for the last several days — where one day you’re in one air mass, the next day things move and you’re in the other air mass,” Hasell mentioned.

When the wind chill approaches -40 or decrease, Hasell mentioned frostbite can set in on uncovered pores and skin in as little as 5 to 10 minutes.
“Yeah, -40 to -47 is considered a very high risk — exposed skin can freeze in five to 10 minutes.
