For this forecast period we are starting off with a large area of high pressure over Ontario and an equally large area of low pressure over the Yukon. The clockwise flow around the Ontario high, combined with the counterclockwise flow around the Yukon low, is creating a widespread southerly flow across the Prairies. This should lead to one more day of warm temperatures across the western Prairies and a couple more days over the eastern half.

Prairie forecast: Potential to turn cool and wet
Forecast issued July 9, covering July 9 to 16, 2025

Prairie forecast: Stormy start to the west, summer heat to the east
Forecast issued July 2, covering July 2 to 9, 2025
We start this forecast period with warm high pressure in place across the eastern Prairies and a developing area of low pressure over Alberta.

Prairie forecast: Looking warm and dry for Canada Day
Forecast issued June 25, covering June 25 to July 2, 2025
A broad but unorganized area of low pressure impacts all three Prairie provinces for at least the first half of this forecast period. Unsettled weather means it will be a difficult forecast to pin down. It also means seasonable temperatures with no big intense heat waves expected—though that doesn’t mean we won’t see a few hot days.

Prairie forecast: Unsettled weather ahead
Forecast issued June 18, covering June 18 to 25, 2025
For this forecast period we start, once again, with no strong systems impacting the Prairies. But, as we head into the weekend a strong area of low pressure is forecasted to develop over the western U.S. This low will impact our region over the weekend, but how and where is a little uncertain.

Prairie forecast: Where did the summer heat go?
Forecast issued June 11, covering June 11 to 18, 2025
Looking at the big picture we start this forecast period with a generally zonal flow across the Prairies as Arctic high pressure slides across the far northern Prairies and weak low pressure moves by to the south. This will bring sunny to partly cloudy skies and near to slightly below-average temperatures.

Prairie forecast: Summer pattern making forecast difficult
Forecast issued June 4, covering June 4-11, 2025
We start this forecast period off with an area of low pressure over far northern Manitoba that is slowly moving off into Hudson Bay. To the west, an area of low pressure is developing over the Yukon which is helping to develop a weak ridge of high pressure over Alberta. Over southern Saskatchewan and Manitoba weak high pressure is in place.

Prairie forecast: Cool and damp, then sunny and warm
Forecast issued May 21, covering May 21 to 28, 2025
For this forecast period, it seems set to dry out and warm up. I suppose that's good for the areas that recently received significant rainfall and not so good for those regions dealing with fires.

Prairie forecast: Cool long weekend expected for Saskatchewan and Manitoba
Forecast issued May 14, covering May 14 to 21, 2025
Across the eastern Prairies, all eyes are on the breakdown of the western trough and the resulting ejection of the final area of low pressure. The weather models are still trying to get a handle on this feature.

Prairie forecast: Hot east, cool west
Forecast issued May 7, covering May 7 to 14, 2025
We saw a strong ridge of high pressure build in last week, which brought daytime highs into the low thirties across parts of the eastern Prairies. Once the ridge collapsed, cooler air moved back in. Well, it looks like we can expect another cycle of building and collapsing ridges. Then, starting on the weekend, the weather pattern should become more energetic thanks to a strong trough of low pressure forecasted to develop off the West Coast.

Prairie forecast: Here comes the summery weather
Forecast issued April 30, covering April 30 to May 7, 2025
Well, one week is up and as I pointed out in last week's forecast, the weather pattern still looks like it is going to flip from a cool-ish spring regime right into a summer-like pattern. This flip should happen over the next few days.
