Temperatures to drop to -30 C the next two nights in Ottawa
A blast of cold Arctic air moved into the Ottawa area Thursday evening, with temperatures set to drop to -30 C over the next two nights.
Ottawa could see its coldest temperatures in years as the polar vortex strengths over the region. Environment Canada has issued an extreme cold warning for the region calling for wind chill values of -40 to -45 Thursday night and Friday morning.
"After moderating during the day Friday, wind chills are again forecast to reach near minus 40 Friday night into Saturday morning," Environment Canada said.
"Those wind chills are quite concerning," David Phillips, senior climatologist at Environment Canada, told CTV Morning Live. "This certainly will be the coldest moment of the winter."
The forecast calls for a low of -30 C on Thursday night, with the wind chill making it feel like -41 degrees. Friday's high will be -25 C ,with the wind chill making it feel like -43 degrees.
Ottawa Public Health has issued a frostbite warning until further notice due to the cold temperatures.
Ottawa is expected to see wild temperature changes over the next few days.
"It's about as close as we get to what we call an Eastern Chinook," Phillips told CP24.
The daytime high will be -25C on Friday, warming up to -14 C on Saturday, before temperatures hit 1 C on Sunday and 0 C on Monday.
Snow squall warning in effect
Environment Canada has also issued a snow squall warning for the region, saying brief, intense snowfall is expected to develop Thursday afternoon and evening.
The weather agency is warning of snow accumulations of up to 5 cm in an hour or two and wind gusts up to 70 km/h.
"Bands of heavy snow are moving through southern Ontario with the passage of an arctic cold front. Heavy snow combined with westerly winds gusting to 60 km/h could produce significantly reduced visibilities at times," Environment Canada said.
"Bitterly cold air will follow in the wake of the front, with very cold wind chill values expected tonight into Friday morning."
Temperature to drop Thursday night
By Thursday evening the temperature will drop dramatically with an overnight low of -29 C. The wind chill will make it feel more like -40 and frostbite could develop within minutes.
Friday’s forecast high of -26 C, and the wind chill will make it feel more like -42. It will be sunny but windy with gusts up to 50 kilometres per hour.
Skies will stay clear Friday evening and temperatures will drop to -27 C overnight.
"Dress warmly. Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant," Environment Canada said. Frostbite can develop within minutes on exposed skin.
Warmer weekend
Things will warm up slightly on Saturday with sunny skies and a high of -14 C.
On Sunday, temperatures will rocket back up to above freezing. The high that day is 1 C, with a 70 per cent chance of snow.
