Winnipeg will see seasonably warm temperatures return on Friday, sandwiched between unsettled conditions on Friday and Sunday.
A passing upper-level low will bring mixed skies to Winnipeg today with breezy westerly winds near 30 gusting 50 km/h. The city will see a chance of showers through the day, although the best odds will be through the morning hours. With the “cooler” upper low over the region, daytime highs will return to seasonal values near 25°C. There might be the risk of an odd lightning strike in the afternoon, but no organized thunderstorm threat exists.
The wind will ease this evening as temperatures head to a low near 16°C under partly cloudy skies.
On Saturday, a ridge of high pressure will move across the region. It will bring sunny skies with temperatures climbing back towards the 30°C mark. Winds won’t be an issue, keeping light out of the west through the day. Temperatures will stay warm on Saturday night with a low near 19°C under increasing cloudiness.
Winnipeg will see a chance of showers or thunderstorms midday Sunday as a trough of low pressure moves through. Timing will be crucial to where that threat develops; if convection holds off until the afternoon, there’s a better chance that the activity will develop east of the Red River into the southeastern corner of the province. We recommend you keep an eye on ECCC’s thunderstorm outlook product in our bulletin viewer Saturday afternoon and Sunday for the latest updates on the thunderstorm and severe weather potential. The chance for showers may redevelop later in the day when a cold front swings through the region.
Aside from the convection, it will be a fairly pleasant day. Temperatures will climb to a high near 29°C with comfortable humidity and southerly winds of 30 gusting 50 km/h shifting to westerly 30 gusting 50 km/h behind the trough.
Long Range Outlook
Settled conditions will move into southern Manitoba to start next week with below-seasonal temperatures moving in on Monday behind the cold front. More heat will return mid-week with variable cloudiness and perhaps the occasional chance of thunderstorms.
Today’s seasonal daytime high in Winnipeg is 26°C while the seasonal overnight low is 13°C.
