Winnipeg will see significantly cooler temperatures through the remainder of the week as mostly cloudy skies bring more chances for rain.
A low pressure system passing through North Dakota will bring substantially cooler conditions than seen over the past few days. As it tracks eastwards, northerly winds of 20 to 30 km/h will develop in Winnipeg, ushering in cooler temperatures from the north and limiting the daytime high to about 22°C. Skies will remain cloudy with showers and thunderstorms developing midday through the afternoon. Much of the precipitation will end up to the south and east of Winnipeg, leaving the city with just a chance of showers or thunderstorms.
The northerly wind will continue at 10 to 20 km/h through the night. Temperatures will dip to a low near 14°C under cloudy skies.
Thursday will bring a lull in the scattered precipitation to the Red River Valley. A flat pressure pattern over the region will bring northerly winds of 10 to 20 km/h to Winnipeg and a high again near 22°C. Winds will shift easterly overnight as the next low approaches the region. Lows should reach around 12°C on Thursday night.
Friday will bring showers back to the region as a low pressure system lifts northeastwards out of the Dakotas. High temperatures will reach around 20°C, kept lower by easterly winds sourced from a high pressure system over Hudson Bay. As the low lifts north through the day, showers or thunderstorms will develop over southern Manitoba. This system then looks likely to support an area of showers and thunderstorms through Friday night.
A warm front lifting northwards will keep temperatures warmer on Friday night. Winnipeg should see a low near 15°C with southeasterly winds of 20 to 30 km/h.
Long Range Outlook
The showers are forecast to taper off Saturday morning, then clearing will work into the Red River Valley. The remainder of the weekend looks pleasant with partly cloudy skies and slightly cooler than seasonal highs near 20°C.
Winnipeg’s seasonal daytime high is currently 22°C while the seasonal overnight low is 8°C.
