Manitoba forecaster Daniel Bezte reviews the outcome of Prairie temperature and rainfall predictions for August from sources including weather models, the almanacs and himself, then looks ahead to September.
Warmer than average August
Warm weather forecasted to continue in September
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.
Weather school: Reasons for big rainfall on the Prairies
Heavy, severe rain needs a couple of conditions before farms in Western Canada get soaked
Heavy, severe rain events need a couple of conditions before farms in Western Canada get soaked: Moisture in the atmosphere is just one of them.
Warmer and wetter future for Prairie farms
Higher humidity and intense rainfall events are all but inevitable as the planet warms
Warming oceans and warming air translate to more humidity. For Manitoba farmers, greater availability of water vapour will make it more likely for precipitation events to tend to the extreme.
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.
Prairie heatwaves and upper highs
Sunshine and sinking air mean rising temperatures for the Prairies
Weather expert Daniel Bezte looks at heat waves and the climate factors that lead to extended periods of high heat in the Prairies.
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.
The theories of tornado formation
Even with the very best of modern technology, the definitive answer hasn’t been found
Even with the very best of modern technology, we’re still not sure about the science behind how tornadoes form.
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.
