A special weather statement for Calgary warns of accumulating snow beginning Wednesday evening as a low-pressure system moves across the region. The live forecast above shows the expected timeline and snowfall amounts for the city and surrounding areas.
What is the timing and expected snowfall?
Snow is expected to start Wednesday evening and continue through Thursday afternoon, with the heaviest rates overnight. Accumulations of 10 to 15 cm are likely across Calgary, with up to 20 cm possible in the foothills west of the city. The system will bring reduced visibility and slippery roads, especially during the Thursday morning commute. Temperatures will hover near –5°C, keeping the snow light but persistent.
How will this affect travel?
Drivers should expect challenging conditions on Deerfoot Trail, Crowchild Trail, and major arteries. Environment Canada advises allowing extra travel time and adjusting speed to road conditions. The City of Calgary will deploy snow-clearing crews, but residential roads may remain snow-covered through Friday.
When will the snow end?
Snow is expected to taper off from west to east by Thursday afternoon, with clearing skies and a chance of flurries lingering into Thursday evening. The live forecast above shows the exact timing for Calgary.
Should I delay travel?
If you can avoid driving during the overnight and early-morning hours, that is recommended. If travel is necessary, leave extra time, use winter tires, and check road conditions on the Calgary weather page.
Is this a winter storm warning?
No, a special weather statement is issued when conditions are significant but do not yet meet the criteria for a warning. It signals that you should prepare for possible disruption. A warning would be issued if snowfall exceeds 15 cm within 12 hours.
