Mild and Cloudy Weather Ahead for Winnipeg With Chance of Snow

Brad

Winnipeg will kick off the new decade with mild temperatures, cloudy skies, and a couple more chances of light snow.

A low pressure system will move through the province today, bringing mild temperatures and plenty of cloud cover. Temperatures will climb to a high near -2°C in Winnipeg today with even warmer highs of 0°C near the U.S. border. Snow will spread southeastwards through the Interlake into southeastern Manitoba today. The band of snow will pass north and east of Winnipeg, but flurries are possible this afternoon and evening. Further south, a second area of light snow will track near the American border, but mostly fall south of the border.

Northwest winds up to 20 km/h will develop tonight behind the low, as temperatures fall to around -10°C. Skies will stay mostly cloudy.

2020 will start off with seasonably mild temperatures across all of southern Manitoba.

Thursday will bring pleasant weather to the region with a high near -7°C under mostly cloudy skies. The chance for flurries will continue through the morning into the afternoon. No notable features will over southern Manitoba, leaving the region with calm winds. Temperatures will dip to -11°C on Thursday night under mostly cloudy skies.

A more organized low will move from SE Saskatchewan into the Dakotas on Friday. As it does, a second low will move into central Manitoba from northern Saskatchewan. The southern low will support an area of snow that will extend some distance northwards along a trough connecting the two. How far north that snow is able to run up the trough is the unknown that will make the biggest difference on Friday. For now, there’s nothing more to say other than that there’s a chance of snow in Winnipeg, but the likelihood increases heading south towards the U.S. border.

Aside from the snow, it will be another seasonably warm day with a high near -6°C and light winds. Any snow that developed would likely be out of the region for the afternoon. Skies stay cloudy on Friday night with a low near -10°C.

Long Range Outlook

Another low pressure system will move through the province this weekend, likely bringing snow to many parts of the province. Behind this low, colder air will begin working its way into the region again. To start off next week, temperatures are forecast to return to seasonal values with variable cloudiness.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -23°C.

Breezy But Continuing Mild in Winnipeg

A breezy northwest wind won’t manage to bring an end to the seasonably mild stretch of weather in Winnipeg.

Breezy northwest winds near 30 gusting 50 km/h will persist in Winnipeg toady as a Colorado Low storm system departs to the east. Unlike most other times, though, this wind isn’t the harbinger of a deep freeze; rather, temperatures will keep roughly where they have been lately with a high near -9°C. Skies will be cloudy through the day with the remnant light snow tapering off. The wind will persist at 20 to 30 km/h tonight with the cloud cover gradually breaking up. Winnipeg will see a low near -15°C, although if the clouds are more stubborn and stick around longer it’ll be closer to -11 or -12°C.

The lack of cold temperatures over the past couple weeks is largely due to the positioning of the Polar Vortex, a persistent winter feature over the Northern Hemisphere. A variety of factors impact where it, and the bitterly cold air associated with it, moves. When the vortex descends into Hudson Bay, it results in the brutal cold snaps across the eastern Prairies.

For the past couple weeks, however, the Polar Vortex has been trundling about the High Arctic. This has kept the coldest temperatures further north and allowed milder Pacific air to cross the Rockies into the Prairies more often. Fortunately (for cold-weather haters), the Polar Vortex is forecast to stay in the High Arctic for the next while. This will allow Winnipeg to continue to see relatively mild temperatures through the rest of the week.

Breezy northwest winds of 30 to 40 km/h will be in place over the Manitoba Lakes and Red River Valley today.

On Tuesday, a ridge of high pressure will cross Manitoba, bringing an end to the breezy winds and mixed skies. Daytime highs will once again be around -9 or -10°C across the region. A broad area of low pressure developing over the western Prairies will push more cloud into the region on Tuesday night along with southerly winds around 20 km/h. Winnipeg’s low will dip to around -12°C.

2020 will start off with relatively pleasant winter weather in Winnipeg. The broad area of low pressure will move into Manitoba on Wednesday. Skies will be mostly cloudy and while no organized snow will move through, a few flurries are possible. Temperatures will be mild with a high near -4°C. The chance for flurries will continue on Wednesday night with temperatures dipping to around -7°C.

Long Range Outlook

The rest of the week looks seasonably mild with plenty of cloud cover. While a few flurries are possible, no organized snow looks likely until the weekend when another low moves through and brings the chance for accumulating snow to the Red River Valley.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -23°C.

Mild Christmas Weather Ahead

Winnipeg will enjoy seasonably mild temperatures right through Christmas Day.

Winnipeg will continue to see daytime highs in the -5 to 10°C range through the first half of the week as a series of weak systems move through the region. Today, the city will see partly cloudy skies with light southeast winds as a high pressure system moves through. Skies will become cloudier tonight as a low pressure system approaches. Tuesday will bring mostly cloudy skies to the region as the low moves through. Winds will stay light, shifting westerly later in the day and there will be just a small chance of flurries. Skies will be cloudy on Christmas Day with light winds again as a ridge of high pressure moves into the region.
