A cold low moving through the province will bring decidedly fall-like weather to the Red River Valley with below-seasonal temperatures, breezy northwest winds, and a chance of showers. The summer hiatus will be short-lived, though, with seasonal temperatures and sunshine returning by the end of the week.
Winnipeg will be under the full influence of the cold low today as it swings through southern Manitoba. Mostly cloudy skies will be in place for much of the day with a northwesterly increasing to 30 km/h gusting 50 km/h keeping temperatures cool. Winnipeg will see a high of just 18°C, a full 8°C below seasonal for this time of year. A few showers are likely in the afternoon as an upper trough extending from the cold low rotates through the region.
The showers will taper off in the evening as winds diminish to around 20 km/h. The clouds will stick around for much of the night as Winnipeg heads to a low near 11°C.
Fortunately, conditions will quickly rebound back to more summer-like weather. As the coldest air moves out of the region on Thursday, a broad area of high pressure will spread eastwards across the Prairies. For Thursday, this means that Winnipeg will see more sunshine as skies become mixed, but the wind will continue out of the north at 20 to 30 km/h. The extra sunshine will help Winnipeg’s high climb to around 23°C. Temperatures will once again drop to a low near 11°C on Thursday night under clearing skies.
Friday will bring things back to seasonal. The ridge of high pressure will arrive and bring light winds, plenty of sunshine, and a high near 26°C. Lows look to fall to around 13°C on Friday night.
Long Range Outlook
Looking ahead to the weekend, the weather looks fairly pleasant. Winnipeg is forecast to see highs in the upper 20s, light winds, and variable cloudiness. There appears to be a chance of scattered pop-up showers or thunderstorms in the afternoons. Sounds a lot more like summer!
Winnipeg’s seasonal daytime high is currently 26°C while the seasonal overnight low is 13°C.
