A Cooler Back Half of the Week

Winnipeg will see a cloudier, cooler back half of the work week in the wake of a low pressure system that crossed the province yesterday.

Winnipeg will see light northerly winds today as cooler temperatures push into the region with a weak ridge. Skies will vary from cloudy to mixed as temperatures climb to a high near +1 °C. Winds will ease from 20–30 km/h early this morning to light early in the evening. Temperatures will dip to a low near -6 °C tonight with mixed skies.

On Thursday, another weak low moving through will drag a cold front southeastwards across the province, bringing more cloud and a chance of flurries to the city. Temperatures will return to seasonal values with a high near -3 °C. Winds will be more of a nuisance, picking up out of the northwest to 30–40 km/h midday. An area of high pressure will move into the province on Thursday night, bringing easing winds and clearing skies. Winnipeg should see a low near -13 °C on Thursday night.

Warmer temperatures will once again begin moving eastwards into Manitoba on Friday.

Long Range Outlook

A warm weekend is in store for southern Manitoba as another upper ridge builds across the Prairies. Temperatures will climb back well above freezing with mainly sunny skies this weekend. Slightly cooler weather is forecast to move in to start next week, but temperatures are still expected to stay generally seasonably mild.

Today’s seasonal daytime high in Winnipeg is -3 °C while the seasonal overnight low is -13 °C.

Spring-Like Warmth Arrives

Many in Winnipeg will remember February for the brutal cold that began the month. March will start on a very different note as spring-like warmth arrives!

After a rather cold night where lows in Winnipeg bottomed out in the low minus 20s, temperatures will climb through the next 36 hours. A Pacific low crossing the central Prairies will push a warm front eastwards, first through Alberta and Saskatchewan today, then Manitoba tonight. In Winnipeg, winds ahead of the front will pick up out of the south to 40 gusting 60 km/h for the afternoon and evening.

Temperatures will climb to a high near -12 °C today, although that wind chill will make it feel rather unpleasant. A sunny start to the day will turn cloudier for the afternoon/evening cloud ahead of the front. There will be a slight chance for some flurries, but the dry southerly ridge outflow winds will likely keep things mostly dry through a majority of the Red River Valley.

Skies will stay mixed to cloudy tonight with winds easing to 30 gusting 50 km/h for most of the night. The warm front will push through overnight, bringing temperatures up to around -2 °C by Tuesday morning.

Long Range Outlook

More warm air is on the way through the second half of the week as an upper ridge builds across the Prairies.

The upper ridge should keep any precipitation at bay until next week, where some snow may be possible as the ridge moves off to the east.

Today’s seasonal daytime high in Winnipeg is -5 °C while the seasonal overnight low is -15 °C.

Mild Friday Turns Colder for the Weekend

Temperatures will begin to fall late in the day as a cold front passes and a moderate north wind develops. The organized snow will end this evening, but the chance for some more light snow will continue overnight. Temperatures will fall to a low near -20 °C with northerlies of 30 gusting 50 km/h easing to around 20 km/h by morning.

On Thursday, another strong Pacific low will begin moving into the western Prairies. In southern Manitoba, a moderate southerly wind of 30–40 km/h will develop ahead of this approaching low. These winds will tap into milder air and send temperatures back up above freezing for the afternoon. Cloud will move in for Thursday night, which will combine with the breezy southerly winds to keep temperatures mild. Winnipeg should see a low near -2 °C. A few flurries are possible through the second half of the night as this system’s warm-sector trough moves through.
