Calgarians enjoyed a surprisingly mild start to the week on Monday, January 19, 2026, but forecasters warn that a shift is on the horizon. Residents should prepare for a notable cooldown expected to arrive by Thursday, marking a return to more seasonal winter conditions.
A Temporary Reprieve from the Cold
The beginning of the week provided a brief respite from the deep winter chill typically associated with a Calgary January. Daytime highs on Monday reached levels significantly above the seasonal average, allowing for more comfortable outdoor activities. This mild interlude, however, is not set to last.
Meteorologists tracking weather systems across Western Canada indicate that a change in the atmospheric pattern is imminent. The jet stream is forecast to steer a colder air mass from the north into Alberta, directly impacting the Calgary region.
Bracing for the Chill Later This Week
The most significant drop in temperature is anticipated to begin on Thursday, January 22. Daytime highs are expected to fall substantially, potentially dipping well below freezing. Overnight lows will also plunge, requiring residents to take necessary precautions for themselves, their homes, and their vehicles.
This forecasted cooldown aligns with broader weather patterns affecting other parts of the country, as indicated by various warnings for blizzards, snow squalls, and extreme cold elsewhere in Canada. While Calgary is not currently under such extreme warnings, the incoming cold snap serves as a reminder of the volatile nature of Prairie winters.
Residents are advised to monitor updated forecasts from Environment Canada as the week progresses. Key preparations include:
- Ensuring home heating systems are functioning properly.
- Checking antifreeze levels in vehicles and ensuring winter tires are in good condition.
- Having emergency kits ready for homes and cars in case of severe conditions.
The weather shift underscores the importance of staying informed during the winter months. While Calgary saw a mild Monday, the remainder of January 2026 is shaping up to deliver a more characteristic winter experience.
