After a cooler than average July, August saw a reversal with all the main reporting stations reporting above average temperatures.

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.
Factors that can cause heavy rainfall
There are several factors that can contribute to an extreme rainfall event, the first is atmospheric moisture.
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.
Relative humidity linked to dew point
The dew point is the temperature that we would have to cool the air down to for condensation (or dew) to begin forming.
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.
Heat waves combine sunshine and sinking air
As we continue our look at heat waves, I figured we should first define what they are by looking at the criteria Environment Canada uses to define heat events.
Prairie forecast: Unsettled weather to continue
Forecast prepared August 13, covering August 13 to 20, 2025
For this forecast period it looks like the active pattern that developed last week will continue with a couple of lows forecasted to impact parts of the Prairies.
Above average temperatures expected
July was a cooler than average month right across the Prairies, with most places coming in just slightly below average.
Prairie forecast: Merging lows bring plenty of chances for rain
Forecast issued Aug. 6, covering Aug. 6 to 13, 2025
For this forecast period we start with a small but fairly potent area of low pressure lifting northwards through Manitoba. Meanwhile, weak high pressure is covering Alberta and Saskatchewan.
