This forecast period starts with a broad, cool area of high pressure stretching across the Prairie provinces. The cool air combined with strong mid-summer sunshine is leading to partly cloudy skies along with the odd shower or thundershower.

Prairie forecast: Seasonably cool with chances of precipitation
Forecast issued July 16, covering July 16 to 23, 2025
Tornado lesson begins with rotating air
Spinning columns of air take many forms, from areas of high and low pressure, to much smaller scale ranging from harmless whirls to devastating tornadoes.
Prairie forecast: Potential to turn cool and wet
Forecast issued July 9, covering July 9 to 16, 2025
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: 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.
Straight-line winds pose nasty threat
Nearly all straight-line winds occur near the leading edge of a thunderstorm, which are made up of areas of updrafts and downdrafts.
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.
Understanding how hail is formed
Most thunderstorms will produce hail; the question is whether or not the hail will grow large enough to make it to the ground without completely melting.
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.
What thunderstorms need to turn bad
In this issue we are going to look at what takes a regular old thunderstorm, and turns it into a severe thunderstorm or, occasionally, into a thunderstorm that you truly remember.
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.
