Our weather pattern looks to be on the brink of a shift as a trough of low pressure begins to develop along the West Coast.
For those of you in Alberta, this will mean cooler and wetter conditions. In Manitoba, it looks like summer will continue for at least one more week. If you are in Saskatchewan, well, you will be stuck in the middle of these two features.

Prairie forecast: Cooler and wetter in the west, dry and warm in the east
Forecast issued Sept. 11, covering Sept. 11 to 18, 2024

Prairie forecast: Summer weather not over yet
It looks like summer is not over yet. After a week of fairly unstable weather across much of the Prairies, it looks like we're moving into a period of stable warm weather to start September.

Hail hits crops at more than 1,600 farms across Prairies
More than 1,600 Prairie farms were hit by hail between July 29 and August 11, with the heaviest damage in Alberta, according to the Canadian Crop Hail Association (CCHC).

Prairie forecast: Warm but unsettled weather
Forecast issued Aug. 21, covering Aug. 21 to 28, 2024
Last week's forecast got off to a rough start. The area of low pressure that pushed through the eastern Prairies ended up as a large upper level low. Because those are slow to move out, they can affect systems trying to move east by backing them up or forcing them to take a different path. So, while the overall pressure pattern across the Prairies was still slack as forecasted, the details got all messed up.

Prairie forecast: Weak systems make for tricky forecast
Forecast issued Aug. 14, covering Aug. 14 to 21, 2024
The slack or weak pattern looks to continue into much of next week, which makes it difficult to pinpoint which areas could see showers or thunderstorms, and on which days. Best chances for precipitation look to be over the eastern Prairies. This type of pattern also makes it difficult to predict where forest fire smoke will be.

Sixty-six per cent chance of La Niña weather emerging, U.S. forecaster says
There is a 66 per cent chance of the La Niña weather pattern, characterized by cold temperatures in the Pacific Ocean, emerging during September-November, a U.S. government forecaster said on Thursday.

Prairie forecast: Temperatures to warm up
Forecast issued Aug. 7, covering Aug. 7 to 14, 2024
For this forecast period, it's looking like the forecasted strong area of high pressure is going to dominate the weather across the Prairies. This should bring plenty of sunshine and warming temperatures. Overnight lows look to be seasonable, so at this point it doesn't look like we'll see heat warnings—but as usual you just never know.

Prairie forecast: Cooler weather coming, but little precipitation
Forecast issued July 31, covering July 31 to August 7, 2024
It's looking like we'll soon see an end to the hot conditions of the last few weeks as upper ridging collapses and the upper flow across the Prairies moves to a straight west-to-east flow. Under this pattern, we should see textbook summer conditions. The only downside is there aren't many chances of precipitation.

Prairie forecast: Heatwave coming to an end
Forecast issued July 24 covering July 24 to 31, 2024
Southern Alberta, southern and central Saskatchewan and Manitoba will see another day or two of hot weather before the northern low drags a cold front southward, which will bring an end to this extended heatwave.

Prairie forecast: Prolonged heatwave expected
Forecast issued July 17, covering July 17 to 24, 2024
The second heatwave of the summer appears to be establishing itself across the Prairies. This heatwave looks to last the whole forecast period as a strong upper ridge builds over central North America. Intense heat will stretch from the southern U.S. to the Arctic ocean.
