Stormy Conditions Likely Across Manitoba – September 3 2026

Colleen Bready, the weather guru you see on CTV every morning, just gave us the low‑down for September 3, 2026. She’s pointing to a fast‑moving cold front that’s set to plunge into Manitoba later this afternoon, and the vibe is anything but calm.

Expect a rapid rise in clouds, followed by pockets of heavy rain and thunder that could roll across Winnipeg, Brandon and the surrounding rural districts. The model data shows the front will bring gusts up to 55 km/h – that’s enough to rattle loose‑leaf papers and give cyclists a nasty surprise.

What’s more, there’s a real‑talk chance of hail the size of a nickel, especially over the southern part of the province. The Environment Canada radar is already flashing a “severe thunderstorm warning” for a swath that stretches from the U.S. border up to the Manitoba‑Saskatchewan line.

Now, we’re not talking tornadoes, but the combination of wind, rain and hail can still cause a few headaches. Bready recommends pulling in any loose outdoor furniture, securing garden tools, and, if you’re driving, keeping an eye out for sudden slick patches on the road.

For anyone planning to be out on the water – be it on Lake Winnipeg or a smaller lake near Dauphin – the forecast calls for rough conditions after 3 p.m. The wind shift could create choppy waves, so a quick check of the marine bulletin is a good idea.

In short, the day will start fairly typical for early September, but by late afternoon the sky will darken, the thunder will rumble, and you’ll want to be indoors, or at least under a solid roof. As always, stay tuned to local updates and heed any warnings that pop up.
