Winnipeg will see temperatures in the upper 20’s for much of the week as the season’s first humid spell builds into the region.

Temperatures will be hot in Winnipeg over the next three days. Daytime highs near 29°C will be in place through Wednesday and are about 7-8°C above seasonal. Overnight lows will rise dramatically over the next few days as southerly winds bring humidity northwards into the province.

This increase in humidity will be one of the most significant changes this week. For the past several weeks, dew point temperatures have remained at relatively low values. This week, dew points are forecast to rise into the low teens on Tuesday, then further into the upper-teens on Thursday. This will be the first occurrence of relatively humid conditions this year.

Besides warm, the next few days will be pleasant. Winds will be a bit breezy out of the south today at 20 to 30 km/h, then will ease to the 10 to 20 km/h range for Tuesday and Wednesday. Winnipeg will see sunny skies today, but the region will see a bit more cloud with mixed skies on Tuesday. On Wednesday, Winnipeg should see partly cloudy skies. The southern Red River Valley will see more cloud as it spreads out of North Dakota ahead of a low pressure system moving towards the region.

Long Range Outlook

More extensive cloud cover will build into the Red River Valley on Thursday as a low pressure system moves into the region. This disturbance will bring a good chance of showers or thunderstorms Thursday night through Friday. A cold front looks to sweep through late Friday, beginning to clear the cloud and humidity out of the region.

The weekend is looking pretty great with seasonably warm highs in the mid- to upper-20’s and plenty of sunshine.

Winnipeg’s seasonal daytime high is currently 21°C while the seasonal overnight low is 7°C.
