Calgarians are set to experience a brief interlude of mild conditions on Thursday before a swift return to seasonal winter temperatures, according to the latest forecast from the Sky Watch Weather Centre.
A Temporary Reprieve from the Cold
Meteorologist Jodi Hughes reported that Thursday, December 4, 2025, will feature clear skies and above-average temperatures, offering residents a pleasant break. The mild weather is expected to make for clear driving conditions across the city, at least for the day.
This mild spell, however, will be short-lived. A pronounced cooldown is forecast to begin on Friday, marking a rapid return to more typical December chill for southern Alberta. The shift serves as a reminder that winter is firmly in control across the Prairies.
Holiday Safety Campaign Launches in Calgary
Coinciding with the changing weather patterns, the Calgary Police Service has initiated its annual holiday Checkstop campaign. The enhanced enforcement program, which began this week, aims to curb impaired driving throughout the festive season.
The campaign involves increased roadside checks and a visible police presence on city streets and highways. Authorities are urging all drivers to plan for safe transportation if they intend to consume alcohol or cannabis during holiday gatherings.
Looking at the Broader Forecast
While Calgary prepares for its temperature swing, other parts of Canada are grappling with more severe conditions. A major winter storm is targeting Ontario, with some regions potentially seeing up to 50 centimeters of snow, though the Greater Toronto Area is expected to be largely spared the worst impacts.
In Atlantic Canada, ferry crossings have been cancelled ahead of another round of wintry weather, highlighting a nationwide pattern of active and disruptive seasonal systems.
Back in Calgary, residents are advised to enjoy the temporary mildness on Thursday but to prepare for the imminent drop in temperature. Ensuring vehicles are winter-ready and having appropriate cold-weather gear on hand will be essential as the cooldown settles in for the weekend and beyond.
