Cool Weather Continues in Winnipeg

Brad Leave a comment

Seasonably cool conditions will continue for a couple more days in Winnipeg as Arctic air spills southwards.

A strong northerly flow aloft will continue over the Prairies for another couple more days. Supported by a strong upper ridge over British Columbia and a stalled vortex over Hudson Bay. This will push an Arctic high southwards through the Prairies over the next 48 hours and bring well below-seasonal temperatures.

In Winnipeg, the city will see a sunny start to the day, then temperatures will climb to a high near +3 °C with northerly winds picking up to around 30 km/h. A disturbance slumping southwards will bring cloud into the region this afternoon, bringing mostly cloudy conditions and a slight chance of flurries. The cloud cover will break up tonight with temperatures heading to a low near -6 °C with light northerly winds.

Cooler temperatures will linger over the eastern Prairies on Tuesday.

The city will see mixed skies on Tuesday as the Arctic high moves from the southern Prairies into the United States. It will be another cool day with a high near +2 °C and again there might be a few isolated flurries with the cloud cover. The northerly winds won’t be as strong as Monday as they pick up to around 20 km/h. The cloud cover will clear out overnight with a low near -5 °C with light winds.

With the Arctic well to the south for Wednesday, westerly winds will move back into the region. This will spread seasonal temperatures back into the Red River Valley with highs reaching 11 or 12 °C. Winnipeg should see plenty of sun with those westerly winds in the 20–30 km/h range. Skies will clear for Wednesday night with a low near +1 °C.

Long Range Outlook

Mild temperatures will move into the region on Thursday as an area of low pressure moves through the province. Highs will climb into the upper teens with breezy westerly winds. A cold front will sweep through the region on Thursday night, bringing cloud, a chance of showers or flurries, and below-seasonal temperatures back to the region for Friday. The sun should reappear for the weekend with temperatures gradually climbing back towards seasonal values.

Next week looks to be on the cloudier side as more unsettled conditions develop across the eastern Prairies.

Today’s seasonal daytime high in Winnipeg is 12 °C while the seasonal overnight low is 0 °C.

Deep Freeze To Slowly Ease This Week

Winnipeg will gradually come out of the grip of bone-chilling cold that’s been in place over the last 10 days.

The polar vortex will slowly shift eastwards this week, allowing warmer temperatures to return to the Prairies. The temperature climb, unfortunately, is relegated mainly to the second half of the week. In Winnipeg, highs will only climb from around -23 °C today to -20 °C on Wednesday with a bit of a southerly wind at times. Overnight lows will hover in the low minus thirties.

Wednesday will be a turning point for southern Manitoba where the bitter cold finally begins to break down.

Long Range Outlook

The rest of the week will bring partly cloudy skies to Winnipeg as temperatures climb back to seasonal values by Saturday. No notable snowfall is in the forecast between now and next week.

Temperatures will likely climb above seasonal values and close to the freezing mark by Sunday or Monday. Get the shorts ready!

Today’s seasonal daytime high in Winnipeg is -8 °C while the seasonal overnight low is -19 °C.

Bitter Cold Continues Through The Weekend

The polar vortex will keep Winnipeg in its grip with dangerously cold temperatures persisting this weekend.

Below-seasonal temperatures will continue this weekend as the polar vortex keeps dangerously cold Arctic air locked over the region. Daytime highs will stay in the mid- to lower minus twenties over the next few days with overnight lows dipping into the minus thirties.

It’s still really cold.

Winds will be light in Winnipeg through the weekend, but with temperatures so cold wind chill values of -40 to -50 will be regular across southern Manitoba this weekend.

Skies will stay mainly sunny.

Long Range Outlook

This bitterly cold weather pattern will finally break down through the course of next week. The polar vortex will begin to weaken and push off to the east through the first half of the week. As it then curls back northwards and reforms over the Arctic, milder Pacific air will begin to spill eastwards over the Prairies.

Daytime highs next week will tart off in the -15 to -20 °C range, but will climb to slightly above seasonal values in the -5 to -10 °C range by the end of the week. Overnight lows look to stay in the -20s through Wednesday night, then begin to warm heading towards next weekend.

Today’s seasonal daytime high in Winnipeg is -9 °C while the seasonal overnight low is -19 °C.

Dangerously Cold Conditions Continue

The bitterly cold Arctic air that has lead to several tragic deaths across Western Canada will stay entrenched over the region for the rest of the week.

The polar vortex will gradually slump through Manitoba in the second half of the week, sustaining the dangerously cold weather in the region. Daytime highs will fall back into the mid-minus 20s by the end of the work week with overnight lows in the minus 30s. Winds will stay light over the next few days.

Dangerously cold temperatures will continue through the end of the week.
RDPS Forecast Sounding for CYWG valid 21Z Wednesday February 10, 2021
Despite the cold conditions, low-level instability will develop this afternoon, producing cloud and light flurries.

Much of the region will see mixed skies with some flurries develop today as temperatures warm and low-level instability develops. Similar to yesterday, the air aloft is so cold that its able to generate cumulus clouds even with surface temperatures in the -20s. The clouds will taper off overnight, and then redevelop on Thursday. With slightly colder temperatures tomorrow, there will be less of a chance for flurries.

Sunny skies return on Friday.

Long Range Outlook

The bitter cold will stay in place for Saturday, but finally some relief will start developing on Sunday. Temperatures will warm back towards -20 °C on Sunday, followed by a gradual trend towards seasonal values through next week.

Today’s seasonal daytime high in Winnipeg is -9 °C while the seasonal overnight low is -20 °C.
