For the first time in a while, the last forecast period did not play out exactly as the weather models predicted, thanks mostly to a strong area of low pressure that moved westwards from the Atlantic into central Ontario last weekend and into the first half of this week. While the low didn’t impact the […] Read more
Prairie Forecast: Sprawling high to bring dry, seasonably warm weather
Issued Oct. 11, covering Oct. 11-17
Prairie Forecast: Building western ridge to bring warming trend
Issued Oct. 4, covering Oct. 4-10
Last week’s weather forecast played out close to what the weather models were predicting. Western regions saw cooler-than-average temperatures move in, while eastern regions saw a brief return to summer-like temperatures. This pattern was a response to an area of low pressure that spun up over the central U.S. during the second half of the […] Read more
Prairie Forecast Update: Wet weather for southern Manitoba, southeastern Saskatchewan
Update issued Oct. 2, covering Oct. 2-4
The strong area of low pressure that the weather models have been forecasting to impact the eastern half of the Prairies on Tuesday and Wednesday is starting to take shape. The latest model runs show the low pushing northward into western Manitoba early on Tuesday morning and then moving off toward northwestern Ontario by late […] Read more
Prairie Forecast: Summer tries to hang on
Issued Sept. 27, covering Sept. 27 to Oct. 4
For being this far into fall, the weather models have been surprisingly accurate. Heck, I didn’t even need to send an update for the last issue! Not sure if I can be as optimistic for this forecast period, as we are moving deeper into fall and starting to see the first hints of winter trying […] Read more
Prairie Forecast: Warm fall weather to continue
Issued Sept. 20, covering Sept. 20-27
Even with some uncertainty in the last forecast, the weather models did a surprisingly good job. At one point it looked like I was going to have to send out an update as the models started trending toward a cooler pattern, but they quickly reversed back to a warm pattern. This brought the expected heat […] Read more
Prairie Forecast: One last push of summer-like temperatures
Issued Sept. 13, covering Sept. 13-20
As we work our way slowly into fall, we are starting to see a more fall-like pattern beginning to develop — especially when it comes to overnight lows. While the upcoming forecast does not look like we see a big fall cooldown, there is more and more deviation developing between different runs of the forecast […] Read more
Prairie Forecast: Summer trying to hang on
Issued Sept. 6, covering Sept. 6 to 13
The weather models seem to be in good agreement for this forecast period, with no strong storm systems expected to impact the Prairies, making for a fairly high-confidence forecast. This forecast period will start off with a generally west to southwesterly flow across the Prairies. A broad but weak area of low pressure is expected […] Read more
Prairie Forecast: Mostly sunny and warm
Issued Aug. 30, covering Aug. 30 to Sept. 6
It’s a straightforward forecast for this period as the general weather pattern looks to be pretty quiet. It starts with a large area of high pressure centred over the Great Lakes with a weak area of low pressure over Alberta. The Great Lakes high will put sunny skies and warm temperatures over much of Manitoba […] Read more
Thunderstorms and straight-line winds
Under the right circumstances they can be powerful enough to cause significant damage
Reading Time: 3 minutes Let’s do a quick recap of July weather. Alberta was spared the impacts of the large Hudson Bay upper low, with continued above average temperatures experienced in June. Edmonton was the hot spot with a mean monthly temperature of 18.6 C, which was about 2.5 C above average. Calgary came in second with a temperature […] Read more
Prairie forecast: unsettled to start then clearing and warmer
Issued Aug. 23, covering Aug. 23 to 30
Once again, the weather models are in good agreement so confidence in this forecast is fairly high. The only possible issue is that the different weather systems are rather weak which means timing of the systems can change easily. This forecast period starts off with two weak areas of low pressure, one over southern Manitoba, […] Read more
