Cool and Settled Weather On The Way

Winnipeg will head into an extended period of slightly cooler than seasonal temperatures and benign weather.

Winnipeg will see cool but comparatively pleasant conditions over the next few days. An Arctic high entrenched over the Prairies will weaken any passing disturbances right into next week. That said, Winnipeg will end the work week with sunny skies today and a high near -14°C. Unlike yesterday, winds will be light today, so conditions outside will be great for getting outside and enjoying winter activities. Temperatures will fall to a low near -27°C tonight, then gradually moderate early Saturday morning as cloud cover moves into the region.

Saturday will bring cloudy skies to Winnipeg as a disturbance slowly pushes eastwards into the Dakotas. Temperatures will warm up to a high near -12°C with light winds continuing. While south-western Manitoba may see some light snow, it doesn’t look like any will fall here in the Red River Valley. Temperatures will dip to a low near -21°C under cloudy skies on Saturday night.

Sunday will bring more cloud to the region with a high near -12°C again. Winnipeg will see a slight chance of flurries, particularly in the afternoon, but should escape any accumulating snow. Temperatures will dip to a low near -22°C again with some clear breaks developing.

Long Range Outlook

Next week looks cool and dry for Winnipeg. The city will continue to see high temperatures in the -10 to -15°C range with overnight lows near -20°C. While the week will bring variable cloudiness, it does not look like the region will see any accumulating snowfall.

Today’s seasonal daytime high in Winnipeg is -8°C while the seasonal overnight low is -18°C.


Extended Forecast Break Ahead
This will be the last forecast post for the next while as I’m taking a break from things and entering into a bit of vacation time. We’ll be back with a forecast again on March 6, 2019.

More Snow With Steady Temperatures

Winnipeg will see 5 to 10 cm of snow beginning today as temperatures stay steady at below-seasonal values through the rest of the work week.

Winnipeg will see more snow push into the city this morning that will persist through much of the night. The snow will come in two batches; the first will move through midday before easing in the afternoon, then the second will develop in the evening and persist through the night. By the time the snow tapers off on Thursday morning, the city will likely see 5 to 10 cm of the white stuff. Once the snow moves off, the city will see mixed skies for Thursday that will further clear out for Friday.

Much of southern Manitoba will see 5 to 10 cm of fresh snow by the time the disturbance laves the province on Thursday morning.

Daytime highs will be fairly steady the next few days, generally around the -15°C mark. Overnight lows, however, will slowly drop as an Arctic high builds in from the west. The city will see a low near -21°C tonight and will then drop towards -27°C by the end the week.

Winds will stay light through much of the snow event today, but will pick up out of the northwest overnight and increasing to 30 gusting 50 km/h for Thursday. Those winds will gradually ease Thursday night into Friday.

Long Range Outlook

Temperatures will continue at below-seasonal values through the weekend, but nothing like the frigid cold seen last week. Daytime highs look to stay in the mid-minus teens while overnight lows dip into the -20s. Winnipeg will see little change heading into the first half of next week.

Today’s seasonal daytime high in Winnipeg is -8°C while the seasonal overnight low is -19°C.

Finally: Snow Brings A Break From The Cold

Winnipeg will see a much-welcome return to seasonal temperatures as snow moves into the region.

A developing disturbance called an inverted trough will move into Manitoba today, bringing cloud, light snow, and much warmer temperatures. Winnipeg will see sunshine this morning replaced by increasing cloudiness in the afternoon. As the cloud pushes in, temperatures will climb to a high around -10°C. Light snow will spread across the Red River Valley this evening and continue through the night. The city should see close to 5 cm of snow by Tuesday morning. With the cloudy skies and inverted trough moving through, temperatures should stay steady near -11°C through the night.

The city will see light snow through much of Tuesday with another 2 to 4 cm likely. Temperatures will climb to a high near -9°C as the inverted trough continues through the province. Snow will taper off sometime late in the afternoon or early evening leaving behind mostly cloudy skies with a chance of flurries. Temperatures will head back to a low near -20°C on Tuesday night.

Much of southern Manitoba will see 4-8 cm of snow over the coming 48 hours, although note that this forecast snowfall map is likely producing slightly higher amounts along the Manitoba-U.S. border than expected.

Another disturbance tracking along the U.S. border will bring more cloud and a chance of light snow to the region on Wednesday. Winnipeg will have cooler high near -15°C. After this disturbance passes, another Arctic high will slowly begin building back into the region. Overnight lows will dip down to around -22°C on Wednesday night.

Long Range Outlook

The rest of the week will bring variable cloudiness and below-seasonal temperatures. The cool conditions won’t be as extreme as the last cold snap, though, with daytime highs in the minus teens and overnight lows dipping into the -20s.

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

Cold Weather Continues

Winnipeg will continue to see seasonably cold temperatures with benign weather through the weekend.

Manitoba will be unable to escape the grasp of an Arctic high that has been bringing extreme cold to Saskatchewan the last few days. Because of this, the next few days will bring fairly similar temperatures with quiet weather.

Today will bring diminishing winds with some cloudy periods as a bit of low cloud moves southwards out of the Interlake. After a clear start to the evening, a disturbance moving through the northern United States will spread cloud cover back into the Red River Valley overnight. Saturday will bring cloudy skies to the region, then clearing will follow on Saturday evening. Sunday will leave the area with mostly sunny skies.

Temperatures all three days will be well below-seasonal. Friday will be the coldest with a high near -23°C, while the weekend will bring highs close to -20°C. Overnight lows for the upcoming 3 nights will hover close to -30°C.

Forecasts show a snow-free weekend for Winnipeg, although some light snow is possible close to the U.S. border on Saturday.

Long Range Outlook

Next week will likely start with a return to near-seasonal temperatures as an inverted trough spreads cloud and snow across southern Manitoba. Winnipeg will return to slightly colder conditions midweek with variable cloudiness.

Today’s seasonal daytime high in Winnipeg is -9°C while the seasonal overnight low is -20°C.
