Skies will gradually clear this weekend in Winnipeg as the Polar Vortex slumps towards the region.

A weak disturbance dropping through the region will bring mixed skies to the Winnipeg area today. Temperatures will be similar to yesterday with a high in the -10 to -15 °C range, but winds will be much lighter at only around 15 to 20 km/h.

Skies will clear out a bit tonight, but a disturbance moving through the United States will spread a bit more cloud into southern Manitoba overnight into Saturday. Temperatures will dip down into the -25 to -20 °C range overnight with light winds.

On Saturday, Winnipeg will again see mixed skies with some morning cloud breaking up into the afternoon. Temperatures will be cooler with highs dipping to the -20 to -15 °C range with light winds.

By Saturday evening, the next big pattern shift for the region will be underway. An axis of colder air will begin building into the Prairies as the Polar Vortex begins to slowly drop southwards through the Arctic. This will entrench this first temperature drop into the region through the rest of the weekend.

Lows will dip into the -30 to 25 °C range on Saturday night with mainly clear skies and light winds.

On Sunday, a weak disturbance slumping through along the leading edge of colder air will slide through the region. It will bring mixed to cloudy skies with a chance of flurries to the region. For the Winnipeg area, a bit of snow will be most likely in the afternoon, while it will be earlier to the north and west. Daytime highs will climb back into the -20 to -15 °C range.

Some clouds will linger on Sunday night ad temperatures dip into the mid-minus 20s.

Long Range Outlook

Next week will be dominated by a single weather feature: the Polar Vortex. It will continue to drop southwards and build into the Prairies, bringing cold weather to the entire region.

Daytime highs will drop below -20 °C early next week with lows dipping close to -30 °C. There will be little change in the following 10 days. Daytime highs will largely sit in the -20s, save for the occasional passing disturbance that brings highs into the low minus teens. Overnight lows will dip into the low -20s or -30s many times right into mid-February.

It will be a prolonged stretch of cold weather that shows little sign of breaking down until late in the month. Extreme cold warnings will likely be issued by the weather office at times next week for the region.

We hope you all have a great weekend and we’ll see you back here in the deep freeze next week!

Today’s seasonal daytime high in Winnipeg is -10 °C while the seasonal overnight low is -20 °C.
