The cold weather warning in place for Calgary, like much of the province, is calling for “extremely cold” wind chill values that could reach between -40 C to -45 C by Wednesday evening. Parts of central Alberta may see a reprieve Wednesday night, but extreme cold is expected to return to most areas later in the week.

Environment Canada and Climate Change warned that risks of extreme cold are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors and those without proper shelter.

“Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill,” the alert stated. “Keep emergency supplies in your vehicle such as extra blankets and jumper cables. If it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.”

Alysa Pederson, meteorologist with Environment and Climate Change Canada, said this weather can happen in December, although it has been a few years.

“In 2017, it was a pretty cold year,” she said. “Extreme cold temperatures, with windchills hitting the -40 C area is a thing that is possible as you lead into and after the solstice.”

The weather warning has reached nearly all of Alberta, excluding some central and southern areas along the western border of the province.

The intense cold settled in near the end of last week due to an extremely cold air mass that descended from Siberia.

Looking forward to the next week of forecasts, while there is set to be two warmer days on Saturday and Sunday (a high of 3 C and a low of -1 C, along with a high of -1 C and a low of -22 C, respectively), the Weather Network’s 14-day forecast shows temperatures sticking around the -15 C range, with lows of -32 C on some days, until at least mid-January.

“We are going to get a little bit of reprieve as we go into Friday and Saturday, essentially ringing in the new year with some warmer weather,” Pederson said. “But then, to get this warm weather, through next week we are getting a pretty big system. All of this arctic air will get pulled right back down through southern Alberta.”

While there will be a bit of a reprieve from the extreme cold temperatures, Pederson said it won’t last long. Environment Canada forecasts Jan. 3 to see a high of -21 C and a low of -26 C, and the following day will hit -25 C.

“Enjoy your weekend if you are out, because once we get past that we will go back to below normal temperatures,” she said.

Pederson added the cold snap may feel especially jarring due to the warm fall Calgarians experienced.

“We haven’t really had temperatures below normal in Calgary for an extended period time, essentially until the start of December,” Pederson said. “This is the first time we’ve had an extended period of cold temperatures in around eight months.”
