Spring Warmth Returns to Winnipeg

Brad Leave a comment

Temperatures will warm in Winnipeg over the coming days as milder air spread across the southern Prairies.

A strong upper-level flow will keep plenty of cloud cover over Winnipeg today. The cloudy conditions will keep things a bit cooler with a high near 12 °C. Winds will stay light out of the southeast through the day. The cloud will move out of the region tonight, leaving clear skies by Tuesday morning with a low near + 3°C.

On Tuesday, a dry trough of low pressure will move in, bringing with it a push of warmer air. Highs will climb into the upper teens under sunny skies with light winds. The cooler air will encroach on the region Tuesday night with temperatures dipping back to a low near +2 °C.

As long as winds are able to turn southerly, Winnipeg will see mild temperatures on Wednesday.

The cooler weather will be temporarily pushed northwards on Wednesday as a compact low pushes into the region from Saskatchewan. Winds will increase out of the south into the 20–30 km/h range with temperatures climbing close to 20 °C. The day will start off sunny, but the cloud will build into the region through the afternoon. The one caveat to highs will be that this system stays far enough north to bring a southerly flow to Winnipeg. If it slumps further south and Winnipeg’s winds stay light or northerly, then temperatures will likely only reach the low teens.

A cold front will sweep through on Wednesday night, bringing breezy northerly winds, cloudy skies, and a chance of showers or flurries. Temperatures will head to a low near the freezing mark.

Long Range Outlook

A ridge of high pressure will bring near-seasonal temperatures to the region on Thursday and Friday. Heading into the weekend, warmer weather is forecast to return, shifting the general weather pattern into seasonal mildness. Daytime highs right into next week are forecast to generally sit in the 15–20 °C range with overnight lows of 4–8 °C. The region should see plenty of sun, but a couple passing systems may bring some showers to the region later in the weekend into the beginning of next week.

Today’s seasonal daytime high in Winnipeg is 15 °C while the seasonal overnight low is 2 °C.

Seasonably Cool Temperatures Ahead

After a cool and windy Friday, temperatures will gradually return towards seasonal values in Winnipeg.

Today will start with moderate northerly winds behind a cold front that moved through overnight. Winnipeg will start off cloudy with north winds near 30 gusting 50 km/h. There will be a chance of flurries early followed by the cloud cover breaking up and clearing through the afternoon. Temperatures will climb to a high near 5 °C. A ridge draped across the region will bring mainly clear skies tonight with a low near -7 °C

The ridge will slide off to the southeast on Saturday, bringing mainly sunny skies to the region. Temperatures will recover a bit with a high near 8 °C and light winds. A few clouds will move in overnight with temperatures falling to a low near -1 °C.

The Prairies will see cooler temperatures on Friday in the wake of a cold front that moved through on Thursday.

Sunday will bring increasing cloud to the region as a long-wave upper trough begins to dig over western North America. Temperatures will nudge closer to seasonal values with a high near 11 °C as southerly winds strengthen to around 30 km/h. Skies should be cloudy by the afternoon and will stay so right through the night. A low pressure system moving into the region will bring a chance of rain to the region late overnight, but the main chance for organized rainfall will wait until Monday. Winnipeg will see a low near +2 °C on Sunday night.

Long Range Outlook

The new work week will start with cloudy skies and a chance of rain with a high in the upper single digits. After the low pressure system moves through, the forecast shows variable cloudiness with temperatures warming into the mid- to upper teens.

Today’s seasonal daytime high in Winnipeg is 13 °C while the seasonal overnight low is 1 °C.

Cool Weather Continues in Winnipeg

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.

Cool Conditions To Bring Gradual Melt

Brad Leave a comment

Cooler conditions will linger in Winnipeg through the rest of the week, bringing a gradual melt to the pile of snow that fell over the last 48 hours.

The upper vortex responsible for 23 cm of snow in Winnipeg over the past 48 hours — the biggest snow event of this winter/spring season — is now trundling off towards eastern Canada. A few flurries will linger in its trail through the day. The snow cover and a cool north wind near 20 km/h bring a cool high near 0 °C. Skies will stay mostly cloudy tonight with light winds and a low near -4 °C.

On Thursday, a trough of cooler air aloft will move into southern Manitoba. It will bring a mix of sun and cloud and northerly winds up to around 20 km/h again. Any snow associated with this system will likely stay over southwestern Manitoba with light amounts. Temperatures will climb to a high around 3 °C in Winnipeg. Warmer highs are likely over the western Red River Valley where slight downsloping from the escarpment helps temperatures into the upper single digits. Mixed skies will stay for the night with temperatures dipping to a low near -5 °C.

Southern Manitoba will see cool temperatures on Thursday, save for the western Red River Valley where downslope winds near the escarpment bring near-seasonal warmth.

A broad area of high pressure will build into the region on Friday, bringing a bit more sun. Winds will pick up out of the north into the 20–30 km/h range with a high near 3 °C. Note that it could get warmer than that, highly depending on how quickly the snow pack over the region melts. Given the discrepancy in snow depth, some areas may see highs a few degrees warmer than others on Friday. Skies will clear out on Friday night with temperatures heading to a low near -7 °C.

Long Range Outlook

Temperatures will return closer to seasonal values on Saturday, then another low pressure system is forecast to move through on Sunday. This disturbance will bring more cloud and a chance for some rain or snow. Cooler and cloudier weather starts next week, followed by a gradual return to seasonal temperatures and generally sunny conditions.

Today’s seasonal daytime high in Winnipeg is 10 °C while the seasonal overnight low is -2 °C.
