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: Summer pattern making forecast difficult
Forecast issued June 4, covering June 4-11, 2025
Prairie forecast: Mostly warm and dry weather expected
Forecast issued May 28, covering May 28 to June 4, 2025
We start off with high pressure dominating most of the Prairies. A large surface high is sitting over the north-central U.S. This is beginning to tap into more heat and moisture, which will allow for warmer daytime highs and nighttime lows as dewpoints creep up.
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.
Prairie forecast: Warm weather gaining ground
Forecast issued April 23, covering April 23 to 30, 2025
We start this forecast period with an area of low pressure exiting the eastern Prairie and taking the rain and wet snow with it. To the west, a weak frontal system looks ready to drop into northern Alberta where it should bring scattered showers.
Prairie forecast: Temperature rollercoaster to continue
Forecast issued April 16, covering April 16 to 23, 2025
Spring is the toughest time to forecast, but this spring is being particularly tough. The atmosphere is in a very meridional flow right now. That means there are lots of troughs and ridges. So, instead of a persistent westerly flow across our region we are seeing warm southerly flows as ridges build, followed by cool northerly flows as the ridges collapse and are replaced by troughs of low pressure.
Prairie forecast: Warm start, unsettled weekend across extreme south
Forecast issued April 9, covering April 9 to 16, 2025
When we have these battles between warm and cold air, there's always a good chance for a storm system or area of low pressure to develop. We've seen this happen a few times this spring and looking at the latest medium range weather models, the Prairies are likely in for a few more storms as the battle continues.
Prairie forecast: Two lows and a high
Forecast issued April 2, covering April 2 to 9, 2025
This forecast period looks to be be defined by two areas of low pressure, one spinning off the west coast and the other spinning over eastern Canada. Exactly how these two lows behave a move will have a big impact on temperatures across the central and eastern Prairies.
