Colleen Bready’s Forecast: A return to summer heat

Colleen Bready has your current conditions and updated weather forecast for August 26, 2025.

If you’re wondering if summer is winding down, it’s not just yet.

Although some days recently have had a fall feel in the air, temperatures across Manitoba will bring a return to summertime heat on Tuesday.

A ridge of high pressure is also helping to keep the sky relatively clear across the province. Most regions, including Winnipeg, will enjoy sunshine or a mix of sun and cloud this afternoon.

Daytime highs in the south will reach the upper 20s, and the low to mid-20s across the north.

A low pressure system north of the province will slip into northern Manitoba Tuesday that will bring afternoon showers to the northeast. As much as 5-10 mm could fall in Churchill.

There’s a good chance showers will move into Thompson this afternoon, too, then Island Lake this evening.

Along the way, Environment and Climate Change Canada says a cold front moving south could trigger thunderstorms over the region this afternoon. They will move along the cold front into the southeast this evening and overnight.

At this point, there is a low chance of showers overnight in Winnipeg and most of the south and northwest.

Behind the cold front, strong and gusting north winds will develop on Wednesday across the south. Temperatures will still reach the mid-20s.

Looking ahead to the Labour Day long weekend, expect hot highs in the upper 20s and sunshine or a mix of sun and cloud in Winnipeg.

Labour Day Monday marks the start of September and meteorological fall.
