Prairie Forecast Update: Low lingers in Manitoba

Issued July 2, covering July 3 to 5

The overall forecast remains on track across both Alberta and Saskatchewan, so only a small update is needed for Manitoba. Across Manitoba, the area of low pressure that has been tracking across the northern half of the Prairie provinces is now forecasted to take a little longer to exit this region. The two main impacts

Prairie Forecast: Alberta low to bring bit of a cooldown

Issued June 28, covering June 28 to July 5

After a fairly active weather pattern over the last few days, at least across the eastern half of the Prairies, it looks like most regions will see much quieter few days to start off this forecast period. Weak upper-level ridging combine with a broad but weak area of surface high pressure should bring typical summer





Understanding atmospheric circulation

METEOROLOGY 101 | Air in our region must contend with a messy interaction of land and water

The first thunderstorms have appeared in our region, so it’s time for our annual look at thunderstorms. But first, let’s continue our Meteorology 101 class to build on the base of knowledge needed to understand thunderstorms in more detail. In our last lesson, we looked at atmospheric circulation. On a simplified Earth, we would have thermally produced

Prairie Forecast Update: A few small tweaks

Update issued May 21, 2023, covering May 21-24, 2023

The weather models are continuing to do a good job with the short- to medium-range forecasts, but there have been a couple of small changes that have been slowly working into the forecast. Weak troughing off the West Coast is still forecasted to kick off the development of a leeside low in Alberta. This low

Prairie Forecast Update: Forecast on track

Forecast issued May 14, 2023, covering the half-week stretch from May 14 to 17, 2023

The weather models have been remarkably accurate for this time of the year. The big weather picture remains the same. There is a large, persistent ridge of high pressure over far Western Canada with an equally persistent trough of low pressure over Eastern Canada. This means western regions will continue to see sunny, dry and

Forecast: Arctic air continues to dominate

Issued March 17, 2023 • Covering the period from March 22 to 29, 2023

When will spring get here? When will the melt start? Those are the questions I’ve heard most in recent days. Thanks to a series of arctic highs, it looks like spring, or the melt, will not move in until early April. We saw the impact of these arctic highs in the last forecast period. For


Weather: Up-and-down temperatures

Forecast issued Dec. 30, 2022, covering the period from Jan. 4 to 11, 2023

Well, the weather over the holiday season played out pretty close to what the weather models had predicted. We experienced a good old cold snap in the days leading up to and including Christmas, and then the warm air flooded in from the west almost exactly the day it was predicted. Thankfully, that warm air

Forecast: Cooler and unsettled weather ahead

Forecast issued July 15, 2022, covering the period from July 20 to 27, 2022

The weather models did a good job with forecasts over the last few weeks, which is fairly typical for this time of the year. By mid-summer, we usually do not have to deal with strong areas of low pressure that can really play havoc with forecasts. This doesn’t mean the forecast will get everything right.
