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.

Explaining severe summer weather: Hail
Understanding the science behind hail on the Canadian Prairies — how it forms and why it tends to be worse in some provinces
Hail is a common and potentially dangerous form of precipitation which is commonly seen during thunderstorms on the Canadian Prairies. But how does it happen?
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.
The ingredients of a Prairie thunderstorm
Sometimes the smallest addition can make a storm truly memorable
Weather columnist Daniel Bezte says Manitoba farmers can expect many thunderstorms every summer, but only some become severe, if they have all the right ingredients.
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.
How smoke changes weather
A lot of variables come into play while trying to understand this interplay
Daniel Bezte column on the complex interaction of wildfire smoke and weather.
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.
Canadian Prairies brace for hot and dry summer
Western Canada saw a scorching spring with little rain, and weather models suggest summer 2025 will bring more of the same
Western Canada saw a scorching spring with little rain. Weather models suggest summer 2025 will be equally hot and dry.
