Brad Leave a comment

Winnipeg will see some more mild weather with some light snow moving through on Monday night into Tuesday.

Winnipeg will see seasonal conditions today as a weak upper ridge slides across the region. The city will see a few clouds today as temperatures climb to a high near -3 °C. The winds will pick up out of the southeast for the afternoon into the 20–30 km/h range. The southerlies will continue tonight as cloud and light snow moves into the region ahead of a low pressure system. This low will move northwards out of the Dakotas along a trough of low pressure moving towards the region tonight. The trickiest aspect to tonight’s snowfall will be the sharp western edge which should fall somewhere over the western Red River Valley. Temperatures will drop to a low near -7 °C.

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.

Temperatures in Winnipeg will climb back to the freezing mark on Saturday.

On Sunday, skies should mix out with a brisk northwest wind continuing into the afternoon before easing. Temperatures will cool off again with a high near -6 °C in Winnipeg. Winds will be calm on Sunday night as another ridge moves across the region with temperatures dropping to a low in the minus teens.

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.

Mild November Weather Continues

After slightly cooler conditions on Monday, warmer and cloudier conditions will build back across southern Manitoba.

Cooler weather will settle over the region today as an Arctic high builds into the region behind a clipper system that moved through North Daktoa last night. Skies will clear out today as winds pick up out of the northwest into the 20–30 km/h range. Temperatures will be a tad cooler than of late with a high near -5 °C. The wind will taper off this evening as temperatures head to a low near -16 °C with a few clouds overnight.

On Tuesday, the Arctic ridge will push off to the southeast while a potent low pressure system develops over Alberta. Between the two, moderate southerly winds will strengthen into the 40–50 km/h range. For Winnipeg, the wind will stay light for much of the day, instead picking up in the evening after the sun goes down. Temperatures should climb to a near-seasonal high around -3 or -4 °C. Skies will become cloudier as the day progresses ahead of the arrival of a warm front.
