Early Taste of Spring Continues, Winter Storm Looms on Horizon

Winnipeg will see March will kick off the same way February ends: with high temperatures near 0°C bringing an early taste of spring to the region.

The mild weather Winnipeg has seen over the past couple days isn’t going anywhere. A mild Pacific flow will continue through the rest of the work week, bringing near-freezing highs to the region. Tonight and Thursday night will both see overnight lows near -10°C.

Winnipeg will see plenty of sun as well. A few clouds will move through the Red River Valley today, but then mainly sunny skies will be in place through Thursday and much of Friday. Some cloud will begin moving into the region late Friday ahead of a low pressure complex organizing in the United States. The cloud cover will keep Friday night’s low warmer, only dipping down to around -3°C.

Long Range Outlook – Winter Storm Brewing

The weather will turn more unsettled for the weekend as a series of low pressure systems move through the region. Mild temperatures will continue in Winnipeg, but cloudy skies will persist through the weekend into the first half of next week.

There will be a couple of chances for snow – or even a rain shower – through the weekend. Come Sunday night through Monday, what may end up as the biggest storm thus far in the 2017/18 winter season moves through. While it’s too early to put much trust in any of the forecasts, some guidance suggests Winnipeg and the Red River Valley may see over 25 cm of snow with this storm system.

A complex, slow-moving low pressure system may bring Winnipeg the biggest winter storm of the 2017/18 season on Sunday night into Monday.

For now, just keep it in mind that there is the chance for a major snow storm to start next week. If you have travel plans involving driving on Monday, consider contingency plans just in case.

Until then, enjoy the beautiful sunshine and mild temperatures!

Winnipeg’s seasonal daytime high is currently -5°C while the seasonal overnight low is -15°C.

Mild Temperatures Bring Late-February Melt

Get the windshield wiper fluid topped up, Winnipeg! A week of mild temperatures is on the way, bringing beautiful weather and sloppy roads.

Winnipeg is finally free from the grip of Arctic air! A persistent westerly flow aloft is forecast to bring above-seasonal temperatures to the city for the remainder of the week. A warm front will move through this morning, sending highs to near +1°C under partly cloudy skies. Winds will start the day out of the south at 15 to 20 km/h, then shift to the southwest and diminish this afternoon. In the evening, a weak cold front will push across the Red River Valley, clearing out skies and sending lows to near -10°C.

Tuesday will bring slightly cooler weather as a ridge of high pressure moves across the region. Winnipeg will still see above-seasonal temperatures, though, as the daytime high climbs to near -2°C. Skies should be mainly sunny and winds will be light. A few clouds will work into the region overnight as lows dip to near -10°C again.

Winnipeg is forecast to see highs above 0°C on Monday as mild air moves thorugh the Red River Valley.

Wednesday will bring more cloud to Winnipeg as it spreads eastwards ahead of the next low pressure system crossing the Prairies. Under mixed skies, temperatures will climb to a high near -2°C with light southerly winds. Temperatures will dip back down to a low near -10°C yet again on Wednesday night with clearing skies.

Long Range Outlook

The remainder of the work week forecast looks pleasant. Another surge of mild air will send temperatures back near 0°C for Thursday and Friday with plenty of sunshine. Heading into the weekend, temperatures continue to look mild, but indications are that skies will be cloudy as a fairly significant low moves across the Prairies. The general pattern looks to be a bit more unsettled through the weekend into the first half of next week, so Winnipeg may end up seeing a batch of organized, accumulating snow to kick off next week.

But until then, enjoy the mild conditions!

Winnipeg’s current seasonal daytime high is -6°C while the seasonal overnight low is -16°C.

Unremarkable Weather On The Way As Temperatures Inch Towards Seasonal

Winnipeg will see very little weather of note as temperatures slowly trend back towards seasonal values.

A low pressure system moving eastwards through northern Manitoba will bring just a few clouds to Winnipeg today as it drags a cold front across the southern Interlake. Fortunately, Winnipeg will remain on the warmer side of the front, and temperatures should climb to a high near -12°C with winds out of the west-southwest at 10 to 20 km/h. The city will see a few clouds tonight as temperatures dip to a low near -19°C with light winds.

Thursday will be a beautiful day in Winnipeg with sunny skies, light winds, and a high near -7°C. Skies will cloud over on Thursday night as outflow from a high pressure system in the United States meets warmer air advecting into the Prairies from the west. Winnipeg should see a low near -15°C.

Friday will bring mostly cloudy skies to Winnipeg. The extensive cloud cover will keep temperatures cooler with the high for the day likely around -9°C. Winds will be light, and it doesn’t appear that there will be any chance for snow, so the day may end up being a relatively pleasant one given how February has gone so far. Winnipeg will likely continue to see a fair amount of cloud on Friday night as temperatures head to a low near -16°C.

Long Range Outlook

The large-scale pattern over North America continues to shift, with the polar vortex now retreating back towards the North Pole and a secondary cold vortex that has been over Northern Manitoba/Nunavut also shifting off to the east. This change in pattern will allow milder air to build eastwards across the Prairies from the Pacific, finally getting southern Manitoba out of the “Arctic pipeline” that’s been in place for so long now.

As a result, it looks like Winnipeg will actually be entering a stretch of near- to above-seasonal temperatures! With the warmer temperatures will come more variability in cloud cover, but that seems like a reasonable price to pay for some warmer weather at this point.

For those hoping for any precipitation, you’ll have to continue waiting, though. Despite the milder air, snow remains elusive in the forecast, with the main storm tracks continuing to pass to the north and south of the Red River Valley. There are some indications that southern Manitoba may see a storm to kick off March – in like a lion, perhaps? – but there’s plenty of time for that forecast to change. We’ll be keeping an eye on it; in the meantime, enjoy the break from the cold!

Winnipeg’s seasonal daytime high is currently -7°C while the seasonal overnight low is -17°C.

The Best Weather…Is No Weather?

It’s steady sailing for Winnipeg through the remainder of the work week with no notable changes in the weather expected.

The persistent Arctic ridge that has been building across the southern Prairies will continue to remain in place for the remainder of the week, bringing very little change to the weather over the next 3 days. Winnipeg will see daytime highs right around the -16°C mark with plenty of sunshine through the remainder of the work week. Overnight lows will dip to around -26°C tonight and Thursday night, but slightly warmer temperatures will move in ahead of a low pressure system on Friday night, keeping lows a bit warmer near -20°C with some cloud cover building into the region.

Long Range Outlook

A low pressure system passing through on the weekend will bring some cloud and a chance of flurries. Temperatures aren’t really forecast to climb too much, but the passage of this low may begin shifting the overall weather pattern and allow seasonal or slightly above-seasonal temperatures to move into southern Manitoba next week.

In the meantime, grab those skates, or skis, or boots, and get out and enjoy the sunshine!

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