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

Issued Sept. 27, covering Sept. 27 to Oct. 4
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.

What makes a tornado?
There are competing theories as to why these destructive storms develop
Reading Time: 3 minutes Though we are near the end of summer and the peak of thunderstorm season, there are still opportunities for severe weather. Let’s look at the most destructive yet awesome weather event associated with thunderstorms: tornadoes.

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
Prairie Forecast Update: Southern areas may get Hilary’s leftovers
Issued Aug. 20, covering Aug. 20-23
An interesting weather pattern is currently in place across western North America with Tropical Storm Hilary taking an unusual northerly track as it comes in off the Pacific Ocean south of California. Tropical storms or hurricanes in that region normally do one of two things: they either recurve back out into the Pacific, or move […] Read more
Prairie Forecast: Upper ridge to bring the heat
Issued Aug. 16, covering Aug. 16-23
After going through a couple of weeks of tough forecasting, with little agreement among the weather models, this forecast period is looking a little more stable with the two main weather models for our region in basic agreement. We start off this forecast with a low over Manitoba that is quickly moving east. To the […] Read more
