The remainder of the work week will feature plenty of sunshine and a stark break from the cooler temperatures of late as daytime highs climb into the mid- to upper-20’s.
The next few days will bring dry, warm conditions to Winnipeg & the Red River Valley courtesy an upper-level ridge building eastwards across the Prairies. This weather feature will keep the clouds away and push daytime highs above-seasonal values as warmer air is drawn northwards out of the United States.
As a result, Winnipeg will see sunny skies today and tomorrow with daytime highs near 24 and 27°C respectively. The upper ridge will move east of the Red River Valley on Friday, and a disturbance will begin moving towards the province out of southern Alberta. Friday will still be quite pleasant, however, with partly cloudy skies and a high near 25°C.
Winds will be out of the west today at 10-20 km/h, calm on Thursday, and strengthen out of the southeast to 20-30 km/h on Friday afternoon.
Expect overnight lows around 10-12°C the next few nights.
Long Range
At this point, it seems quite likely that a low pressure system will move through late overnight on Friday into early Saturday morning. This system may end up being the first organized nocturnal thunderstorm event of the season, and would likely move into Winnipeg & much of the Red River Valley on Saturday morning. Whether or not there end up being thunderstorms, rain is definitely likely with anywhere from 5-20 mm possible as it moves through.
There’s uncertainty in how quickly this system will clear out, so Saturday may end up remaining fairly cloudy, or we may see sunshine build back into the region in the afternoon. Sunday will likely bring mixed skies to the region again. Both days look to bring highs around 20°C to Winnipeg and lows near 10°C.
After the weekend, Winnipeg should see a couple more dry days before another chance for unsettled conditions mid-week.
Winnipeg’s seasonal daytime high is currently 22°C while the seasonal overnight low is 9°C.
