Mild Friday Followed by Cooler, Unsettled Weekend

Brad

Spring weather arrives in Winnipeg today with plenty of sunshine and a return to seasonal temperatures. The weekend will bring unsettled conditions as a pair of disturbances move through.

Seasonal temperatures will return to Winnipeg today as a breezy southwest wind pushes milder Pacific air back into the region. Winds will strengthen to 30 gusting 50 km/h through the morning under sunny skies. As a low pressure system moves towards the province from the northwest, a few clouds will begin to arrive through the afternoon.

Seasonal temperatures will return to Winnipeg today thanks to a breezy southwest wind.

Skies will cloud over this evening as the low moves through the region, bringing with it a chance of showers. Winds will ease, then shift northwesterly overnight as a cold front swings through. The cloudy conditions will persist on Saturday with a lingering chance for showers gradually tapering off. It will be cooler on Saturday as northwest winds of 30 to 40 km/h limit temperatures to just a couple degrees above tonight’s low.

Skies will clear out later on Saturday afternoon, then winds will ease and temperatures will dip below freezing on Saturday night.

Another low pressure system will approach the region on Sunday, bringing increasing cloudiness and breezy west-southwest winds again. Temperatures will again climb into the mid-single digits. By the afternoon, a chance of showers will develop, but much of the precipitation is forecast to fall north of the area. Much of the cloud will stick around on Sunday night with a continued chance of showers or flurries.

Long Range Outlook

Conditions will improve next week when a more sustained period of seasonal temperatures moves into the region. A westerly flow will bring several disturbances across the province through the week, resulting in variable cloudiness and a few chances for rain.

Today’s seasonal daytime high in Winnipeg is 11°C while the seasonal overnight low is -1°C.

Seasonably cool temperatures will start the week in Winnipeg, but the city will see a quick return to milder temperatures.

An Arctic high moving through the region today will bring cooler temperatures to Winnipeg with a high near -10°C. Fortunately, that unpleasant north wind that developed yesterday afternoon will be absent today. Temperatures will dip down to around -16°C tonight as the high exits the area and light winds shift southerly.

On Tuesday, the region will see near-seasonal temperatures as highs climb to around -4°C. Winds will stay light through the day and skies should be mainly sunny. This will be a great day to get outside and enjoy the increasing warmth of the March sun! On Tuesday night, a potent low crossing the northern Prairies will begin to affect the Red River Valley. Winds will pick up out of the south overnight into the 30 to 40 m/h range as skies cloud over. Temperatures will dip to a low near -8°C.

Long Range Outlook

Thursday will bring more warm weather, but a cold front moving through on Thursday night will send daytime highs back into the low minus single digits for the end of the week. Seasonably cool temperatures will persist through the weekend with the potential for another round of accumulating snow across southern Manitoba.

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

Strong southerly winds will develop over the Red River Valley on Friday.

It looks like Winnipeg will see a fair amount of cloud, but some sunny breaks are likely. The wind will gradually ease on Friday night as temperatures head to a low near -3°C. Skies will stay mostly cloudy through the night.

Long Range Outlook

Mild weather will continue into the weekend with highs at or above freezing on Saturday. A fairly expansive low pressure system will spread snow across the southern Prairies on Saturday, pushing into Manitoba on Saturday night through Sunday. Winnipeg will likely see some snow from this system, but it’s unclear right now exactly how much the city will receive.

Model forecasts suggest that the heaviest snow will be well north of the city, falling from WestMan eastwards across the Interlake and onwards to the Ontario border. If this were the case, Winnipeg would see somewhere around 2 to 5 cm of snow from this system. That said, small changes in the track of this system, north or south, could significantly change the amount of snow the city receives. We’ll take a closer look at this system’s snowfall potential in Friday’s forecast!

Today’s seasonal daytime high in Winnipeg is -4°C while the seasonal overnight low is -15°C.
