And you thought February was bad. March is starting out much worse, with Environment Canada issuing extreme cold warnings throughout the province for tonight.Temperatures are expected to plunge to -29C in Calgary tonight (The Weather Network is predicting -32C) under mostly clear skies. It will be well short of the record low of -36C in 1911, but thanks to a 20 km/h north wind it will feel more like -40C.“Frostbite in minutes,” reads the terse statement by Environment Canada. The agency’s website features a map of Alberta, solid red with warnings from Wood Buffalo National Park in the north to Waterton Lakes National Park in the south.The wind chill in Calgary should moderate by Saturday afternoon, but return overnight in parts of southern Alberta. In Calgary, the high will be -20C under sunny skies, then falling to -29C in the evening.This latest temperature free-fall comes only days after The Weather Network issued a long-term forecast promising a sudden flip to spring weather in late March across Canada.“The crack in the armour of winter is showing and it’s really going to break down almost all at once through to the middle to the latter half of March,” said the network’s chief meteorologist Chris Scott earlier this week.By Monday, the cold snap should just be a painful memory, with a forecast high of -7C. The Weather Network is predicting a steady improvement after that, with a high of 5C in two weeks.
