Calgary Has Beaten a Weather Record Set More Than 100 Years Ago

At about 7:00 Monday morning, Calgary dipped to minus 32.4 degrees beating the old record by .2 degrees. And at least twelve low temperature records have been broken, with the coldest being Sundre coming in at minus 41.6C. That's prompting calls from the Catholic and public schools to warn parents about letting kids stand outside to wait for the bus.   The frigid temperatures also cancelled bus service in the Chinook Edge School District.

The lowest windchill was in Camrose, where the wind makes it feel like minus 50C. The record low temperature for Calgary is minus 32.2 set in 1893.  The last time the city hit minus 40C was in 1997.
The Arctic air mass giving us the cold air will slowly move east beginning Tuesday and will be replaced by milder Pacific air. A low in the Pacific will push rain onto the west coast, snow in the BC mountains, and warmer weather for Alberta.

We should hit minus 8 Tuesday, then go above zero starting Wednesday. By Friday, chinook conditions may develop.   It won't be warm enough to melt much of the snow, but road and highway conditions will improve.
