Benign Weather Ahead for Winnipeg

After receiving a fresh blanket of snow overnight, Winnipeg will see quiet conditions over the next couple days with near-seasonal temperatures.

A sprawling Arctic ridge will push into Manitoba today, bringing partly cloudy skies and cooler temperatures. Winnipeg should see a high near -6 °C today with breezy northwest winds this morning easing for the afternoon. Temperatures will dip to a low near -12 °C tonight under clear skies.

On Saturday, a trough of low pressure moving across the province will gradually spread more cloud into the region. More warm air will push into the region with this disturbance, and Winnipeg’s high should climb back towards the freezing mark. Winds will pick up out of the south into the 20–30 km/h range midday and then taper off in the evening as the trough moves through. Temperatures will dip down to a low near -7 °C with winds picking up out of the west-northwest to around 30 km/h by Sunday morning. The city will see a chance of some light snow overnight, but most of it should keep to the north.

Long Range Outlook

Next week, the polar vortex is forecast to retrograde northwards towards the pole, drawing the colder air northwards and allowing more seasonably mild air to push across the Prairies. As a result, Winnipeg will likely see variable cloudiness with highs in the -5 to 0 °C range and overnight lows in the -5 to -10 °C range. There will likely be a chance of snow or two as the occasional Pacific impulse rolls through, but overall it’d be hard to ask for a better late-November week in Winnipeg!

Today’s seasonal daytime high in Winnipeg is -3 °C while the seasonal overnight low is -11 °C.
