Cold End to the Week, Milder Temperatures Return for the Weekend

An Arctic high will bring cold weather to Winnipeg today, but seasonal temperatures return alongside some flurries for the weekend.

A sprawling Arctic high will move through southern Manitoba today, bringing with it colder weather. Winnipeg will see a seasonably cold high of -18°C with light winds. Skies will stay sunny for most of the day, but there will be a chance of some cloud moving in late in the day as it drifts towards the region from the northwest. Cloud cover will continue to build in tonight with southerly winds of 10 to 20 km/h. A weak warm front pushing into the region will help keep temperatures a tad warmer than last night with a low near -24°C.

Saturday will bring mostly cloudy skies as an upper-level disturbance rolls over the region. Temperatures will rebound nicely to a near-seasonal high of -11°C with light winds. Some flurries will move through over the course of the day, but will be most likely through the morning hours. The cloud will break up a bit for Saturday night as temperatures head to a low near -20°C.

The city will see mixed to cloudy skies on Sunday as another low pressure system begins to build across Saskatchewan. Temperatures will climb back to around -9°C, but winds will pick up out of the south to around 30 km/h through the afternoon. Those winds will persist through the night alongside cloudier skies and keep temperatures steady around -10°C.

Long Range Outlook

More flurries are likely on Monday as mild air continues to push into the region. Temperatures will stay seasonably warm through Tuesday with highs climbing to around -6°C. A cold front is forecast to sweep through mid-week, bringing a chance for some more light snow and a return of colder weather. Through the second half of the week, daytime highs are forecast to drop back into the -15 to -20°C range with overnight lows dipping into the -20 to -25°C range.

These cooler conditions will likely stick around through the weekend; the shift in temperatures will be largely driven by the polar vortex as it shifts back from the High Arctic into Hudson Bay, bringing bitter cold to Canada’s eastern Arctic and supply colder air to the eastern Prairies.

Today’s seasonal daytime high in Winnipeg is -10°C while the seasonal overnight low is -20°C.

Becoming Cooler With Light Snow

Winnipeg will see mild temperatures today give way to cooler temperatures and light snow as a cold front drifts southwards.

The city will enjoy a mild high near -6°C today as sunny skies slowly give way to increasing cloudiness in the afternoon. Winds won’t be too much of an issue either with morning southerlies of 20 to 30 km/h easing off through the morning. Temperatures will begin to fall as the cold front moves into the region this evening and skies fully cloud up. Winnipeg will see a low near -15°C with some light snow beginning overnight.

Thursday will bring cloudy skies to the city with flurries as temperatures recover only a couple degrees to a high near -13°C. Winds will persist out of the north in the 20 to 30 km/h range through the day. The snow will taper off sometime midday into the afternoon as drier air pushes in. It won’t pile up too much, but the city could see a couple centimetres by the time it ends. Heading into the evening, winds will ease as temperatures head to a low near -23°C.

A ridge of high pressure will slump through the Red River Valley on Friday, bringing gradually clearing skies and cool temperatures.

Today’s seasonal daytime high in Winnipeg is -10°C while the seasonal overnight low is -21°C.

Cool Start, Then Warming Mid-Week

Cooler temperatures return to start Winnipeg’s week as an Arctic high moves through the Prairies. The cold will be short-lived, though, with milder temperatures expected to return mid-week.

Winnipeg will see partly cloudy skies with a seasonably cool high near -14°C today. The colder weather is moving into the region with an Arctic high that’s building across the Prairies behind a low that moved through overnight. These cooler conditions will also be joined by a northwesterly wind of 20 to 30 km/h today. This will produce wind chill values in the -20 to -25 range through the day, so it’ll feel noticeably chillier than just the temperature might make you believe.

Some cloud cover will move through tonight as temperatures drop to a low near -23°C with light winds. This will be the coldest night since the temperature dipped to -28.7°C on January 20th. There will be a chance of some light, non-accumulating flurries as the cloud moves through overnight.

With the ridge over the region winds should stay light through the day out of the west-southwest.

A low pressure system will move across northern Manitoba on Tuesday night, spreading slightly warmer air across the southeastern Prairies. Winds will pick up out of the south overnight to 20 to 30 km/h as temperatures rise to around -12°C by morning.

Wednesday will bring increasing cloud to Winnipeg with a mild high near -6°C. The southerly winds will be quite noticeable to star the day at 30 gusting 50 km/h, but will ease heading into the afternoon.

A trough moving through this evening will usher in westerly winds that will start to break up the cloud cover. Temperatures will dip to a low near -7°C as winds ease.
