Heavy snow hits Alberta, Sask. on Monday ahead of an Arctic cooldown
Snowfall warnings are in effect for a period of heavy snow and strong winds to start this new work week across Alberta and Saskatchewan
Following mild conditions over the weekend, a significant shift in the weather is expected for parts of Alberta and Saskatchewan as fresh snowfall sweeps through the region. This could lead to potential travel delays and hazardous road conditions. Snowfall warnings are in effect.
DON’T MISS: Canada’s first countrywide Arctic air outbreak arrives to end November
The snowfall will arrive just ahead of an Arctic air mass forecast to surge across the region, bringing a sharp drop in temperatures. This weather pattern could mark the arrival of Canada's first widespread Arctic air outbreak to close out November.
Be sure to allow extra time for travel, slow down and maintain a safe following distance as conditions deteriorate.
Snowfall warnings in effect with 10-20 cm possible Monday
Snowfall will impact Monday's commute times across southern Alberta, with Calgary experiencing peak snowfall rates at around 1 cm per hour through the morning. Heavier snowfall, reaching 2-4 cm per hour, is expected closer to the Canada-U.S. border.
It's a particularly challenging forecast for Calgary, with current projections indicating totals exceeding 10 cm, though the city is expected to see accumulations within a few centimetres of this benchmark.

A typical November usually generates 20 cm of snow for Calgary, but so far, it has only seen 3.2 cm to date. Since September, only 9.6 mm of precipitation has been recorded, just 14 per cent of the average.
Gusty winds up to 40 km/h could lead to reduced visibility and blowing snow in some areas. Snow is expected to taper off by late Monday afternoon.
In southwestern Saskatchewan, light snow begins early Monday morning in areas such as Swift Current, Cypress Hills, and Moose Jaw. Snowfall will persist throughout the day, with accumulations focused along and south of the Trans-Canada Highway, easing early Tuesday morning.
