Cold Friday Followed by Cloudy and Milder Weekend

Brad

A passing low will delay Winnipeg’s upcoming cold snap for the weekend, but the coldest weather of the season arrives next week.

An approaching Arctic ridge will bring sunny skies and seasonably cool temperatures to the region today. Winnipeg will see a high near -18°C with westerly of 20 to 30 km/h will result in wind chills near approaching -30 for much of the day. The winds will drop off this evening followed by temperatures dropping to a low near -30°C.

Hot on the heels of the Arctic high, another low pressure system will begin crossing the Prairies on Saturday. This system will spread cloud into the Red River Valley through the day alongside southeasterly winds of 20 to 30 km/h. Temperatures will climb slightly higher than Friday to around -16°C, but that wind will still make it feel rather cool with a wind chill near -25. The winds will persist through the night near 20 km/h with temperatures hovering near -15°C.

Temperatures in southern Manitoba will dip to -30°C or colder early Saturday morning.

Skies will stay cloudy on Sunday with temperatures climbing to a high near -12°C as the southwesterly winds slowly taper off. There will be a chance of flurries through the day, but by the time this low is arriving here it will be increasingly cut off from any moisture sources and be in the process of snowing itself out. The winds will die off in the evening as temperatures head to a low near -15°C.

Long Range Outlook

The seasonably mild conditions will stick around for Monday as another disturbance rolls through the region, possibly bringing some light snow. After it passes on Monday night, a potent Arctic high will slide south along the Rocky Mountains with broad ridging extending eastwards across the Prairies.

Long-range outlooks show a prolonged period of below-normal temperatures developing over the Canadian Prairies.

While Manitoba may avoid the coldest temperatures – they will be further west closer to the Rockies – it will still be a pronounced cold snap. Daytime highs will drop into the -20s (possibly even the low minus 20s) for much of the week. Some moderation looks possible with a low passing to the south on the weekend, but an even stronger push of cold air will likely move into the eastern Prairies after it passes. It’d be a good time to make sure your vehicle’s block heater is working and that your long johns are ready to go! Stay warm out there.

Today’s seasonal daytime high in Winnipeg is -13°C while the seasonal overnight low is -24°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.

RDPS 10m Wind Forecast valid 21Z Monday December 30, 2019
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

Brad

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.

Warm Weather Arrives for the Weekend

Brad

Winnipeg will see variable cloudiness over the coming days as a milder Pacific air mass brings above-seasonal temperatures back to the region.

Seasonal temperatures will give way to Pacific warmth this weekend as it spreads eastwards across the southern Prairies. The city will see a high near -9°C today with southerly winds picking up to around 20 km/h later this afternoon. Skies will stay mixed through the day. Some clearing will push into the region tonight with brisk 30 km/h winds. Temperatures will head to a low near -12°C.

Saturday will bring partly cloudy skies to the region as temperatures climb to a high near 0°C. Winds will start the day near 20 km/h and ease for the afternoon. Winnipeg will see variable cloudiness on Saturday night with temperatures dipping to a low near -7°C.

Temperatures will climb to near or just over the freezing mark across southern Manitoba on Saturday.

A low pressure system will push into the Interlake on Sunday, bringing more warmth to the region with mixed skies.

Winds will shift to the west later in the day with a bit more cloud pushing in for Sunday night. Temperatures should dip to a low near -10°C.

Long Range Outlook

Beautiful December weather will continue right through next week with mild highs in the -5 to 10°C and mixed to cloudy skies. No significant snow is in the forecast.
