Calgary Weather Update: Showers and Thunderstorms Expected Tonight
As of 3:00 PM MDT on Sunday, August 9, 2026, Calgary is experiencing partly cloudy skies, with the temperature recorded at Calgary International Airport. The forecast for tonight calls for mainly cloudy conditions with a 60 percent chance of showers and a risk of thunderstorms. Residents should be prepared for potential precipitation and possible thunderstorm activity as the evening progresses.
Temperatures are expected to drop to around 12°C overnight, providing a mild but damp evening. The sun rose at 6:14 AM and will set at 9:09 PM, giving Calgary residents a full day of daylight before the unsettled weather moves in. While the current conditions are calm, the chance of showers and thunderstorms highlights the variability of Calgary’s summer weather, which can change rapidly.
For those planning outdoor activities, it’s advisable to keep an eye on the sky and have an umbrella or rain jacket handy. The risk of thunderstorms means that lightning could accompany the showers, so it’s important to seek shelter if thunder is heard. As always, staying updated with the latest forecasts from Environment Canada is recommended, especially with such dynamic weather patterns.
In related news, Calgary’s weather often makes headlines, but today’s focus is also on a tragic story from northern Alberta, where RCMP are investigating the homicide of a 12-year-old Edmonton boy after remains were found. This serves as a reminder that while we monitor the skies, we also keep our communities in our thoughts. Stay safe, Calgary, and be prepared for a potentially stormy night.
