Prairie forecast: Cool east, warm west

Forecast issued September 3, covering Sept. 3 to 10, 2025

We start this period with a large upper low over northern Ontario, an area of Arctic high pressure building southwards over Manitoba and strong but narrow upper ridge of high pressure over B.C. This particular setup is going to bring cool temperatures over the eastern Prairies for the next several days. Western regions will stay on the mild side.

Prairie forecast: Warm and dry for the long weekend

Forecast issued August 27, covering Aug. 27 to Sept. 3, 2025

This forecast period is looking straightforward as surface high pressure and upper-level ridging looks to dominate the forecast. This should bring what looks to be an extended period of sunny skies and warm to hot temperatures.

Prairie forecast: Sunny, warm end to the month

Forecast issued August 20, covering Aug. 20 to 27, 2025

To start this forecast period, we have an area of low pressure developing over Montana. This will help bring one more day of intense heat over southern Saskatchewan and a hot day over Manitoba. That same low will bring partly cloudy skies and the chance of showers to a good portion of Alberta.
