Mild and Windy Weekend Ahead

Brad

Winnipeg will see cloudy skies and warm temperatures for one more weekend before cooler temperatures return.

Winnipeg will see cloudy skies with a chance of flurries as another disturbance moves through the region today. Temperatures will be mild with a high near -2°C with light winds. A weak ridge of high pressure will cross the province tonight, keeping skies on the cloudier side and winds light. The city will dip to a low near -9°C.

The major weather maker for the weekend will move into the Prairies on Saturday. A rather strong low pressure system will begin pushing into central Saskatchewan on Saturday, bringing with it a strong push of mild Pacific air. Winnipeg will see more cloud on Saturday with increasing south-southeast winds to 30 gusting 50 km/h. Temperatures will climb to a high near -5°C, then continue to climb overnight to around -2°C. The winds will ease for a short period on Saturday night, then pick up out of the northwest to 40 gusting 60 km/h early Sunday morning as the low passes.

Moderate west-northwest winds will develop over southern Manitoba on Sunday in the wake of a departing low pressure system.

Sunday will be a windy day with winds gradually easing to 30 gusting 50 km/h as temperatures stay steady near -3°C. There will be a chance for a few flurries as the clouds finally begin pushing off to the east. The departure of the low will usher in a significant pattern change for our weather, bringing an end to the persistent seasonably mild conditions that have been in place for a while now. Temperatures will dip to a low near -12°C on Sunday night and continue to cool into next week.

Long Range Outlook

Winnipeg will likely see a fair amount of sunshine through the first half of next week, but daytime highs will slip from around -10°C into the mid-minus teens. A weak low is forecast to pass through mid-week, which will then usher in another push of colder air, sending highs even cooler towards -20°C for the end of the week. No significant snowfall is forecast.

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

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.

RDPS 2m Temperature Forecast valid 21Z Wednesday January 1, 2020
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

Brad Leave a comment

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.

End-of-Week Snow Brings Seasonal Temperatures Back

Brad

Temperatures in Winnipeg will slowly climb through the rest of the work week, finally reaching seasonal values on Friday when a passing low pressure system spreads snow through the region.

The cold weather will still be in full force today as an Arctic ridge moves across the region. Temperatures will climb to only -18°C in Winnipeg today, but fortunately the wind will be light. The warmer air will begin it’s gradual shift eastwards later in the day, spreading some cloud into the region for tonight. Temperatures will dip to a low near -24°C with light winds.

Thursday will bring partly cloudy skies to the city as the Arctic ridge slowly weakens. Temperatures will climb slightly with Winnipeg’s high expected to reach around -15°C with light east winds. More cloud will push into the region on Thursday evening with light snow likely beginning sometime after midnight. Temperatures will gradually rise to around -12°C by Friday morning.

NAM 24hr. Snow Accumulation Forecast valid 00Z Saturday December 14, 2019
Accumulating snow will move through southern Manitoba on Thursday night through Friday morning.

Light snow will continue on Friday morning across the Red River Valley. Winnipeg and the Red River Valley will receive 5 to 10 cm of fluffy snow before it tapers off. The low pressure system responsible for the snow will push off to the east for Friday afternoon, leaving the region with a few flurries and strengthening northerly winds. By mid-afternoon, winds will pick up to 30 gusting 50 km/h as temperatures drop into the mid-minus teens. A chance for flurries will continue into the evening hours, but some clearing will move in overnight as temperatures dip to a low near -24°C.

Long Range Outlook

Another Arctic high will move through the region this weekend, bringing more cold weather. Winnipeg will see daytime highs near -20°C with overnight lows in the -20 to 25°C range. The region should see plenty of sunshine.

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