It will be relatively pleasant spring conditions in the Winnipeg area over the next few days as seasonably cool temperatures combine with a mix of sunshine and flurries.
An Arctic cold front will sweep through southern Manitoba to end the weekend, bringing colder weather to start next week.
While the seasonal daytime high for the region has finally climbed above the freezing mark, temperatures in Winnipeg will run just a tad on the cool side over the coming days. Highs will climb very close to freezing today and tomorrow, with the more snow-free urban parts of the city possibly reaching the seasonal high. Overnight lows will dip into the -5 to -10 °C range tonight.
A cold front will swing through the region on Saturday, bringing mixed skies to the region with a slight chance of flurries overnight. Winds will pick up out of the north into the 20–30 km/h range and then ease with the flurries overnight. Overnight lows will dip into the -15 to -20 °C range behind the front.
Temperatures will cool off a bit for Sunday with highs dipping back towards the -5 °C mark. There will be a bit more sun, which means again that some areas will likely see temperatures climbing closer to the freezing mark if they have less snow. Another cold front will swing into the region on Sunday night, ushering an Arctic air mass back into the province along with some more flurries.
Long Range Outlook
Seasonably cool weather will start off next week with overnight lows close to -20 °C and daytime highs in the -5 to -10 °C range. It will start to warm up mid-week followed by a chance for some snow in the second half of the work week.
Today’s seasonal daytime high in Winnipeg is +2 °C while the seasonal overnight low is -9 °C.
Seasonal March warmth will stick around in Wininpeg this week, but a passing low pressure system will clip the province tonight and bring some fresh snow to the region.
Southern Manitoba will be clipped by a passing low pressure system on Tuesday night; accumulating snow will fall through most of the Red River Valley and southeastern corner of the province.
An upper ridge over the west coast that has maintained downstream roughing over the eastern Prairies has been the driver behind the cooler temperatures across southern Manitoba over the last several days. Fortunately for us, this feature has begun to collapse and will allow milder air to push eastwards across the Prairies.
Before that happens, though, a compact low pressure system will impact the region tonight. It will spread snow through North Dakota today, then into Southern Manitoba and Minnesota tonight. Much of the heaviest accumulations will remain south of the border, but accumulating snow will still fall across the region. Winnipeg will likely see 2–4 cm of snow by Wednesday morning while amounts increase into the 5–10 cm range to the southeast. The heaviest swath of snow, likely 10–15 cm will from eastern North Dakota into the Kenora, ON region.
Fortunately, winds will stay fairly light through the event, snow blowing snow won’t be too big an issue overnight into tomorrow.
Aside from tonight’s snow, the weather will be quite pleasant with sunny to mixed skies and light winds through much of the week. Daytime highs will hover just on the cold side of freezing, while overnight lows will have a bit more variability. Tuesday night will likely be the coldest night of the week as clear skies combine with the fresh snow cover to drive lows into the -15 to -20 °C range. Other nights this week will likely see low near -10 °C as warmer air begins moving into the region.
Long Range Outlook
A low pressure system passing to the north will bring some cloud and a chance of flurries to the region on Friday into Saturday, then sunshine should return to end the weekend and kick off next week. Temperatures may cool slightly on the back-side of that system, but near-seasonal temperatures should return by mid-week.
And like we’ve mentioned before, daytime highs will vary depending where you find yourself in Winnipeg; more urban parts of the city, especially those close to the downtown core, will likely find plenty of melting and highs near or even a touch above freezing in the coming days as more of the dark surfaces are exposed and able to absorb heat from the strengthening spring sun.
Enjoy the beautiful weather ahead!
Today’s seasonal daytime high in Winnipeg is +1 °C while the seasonal overnight low is -9 °C.
It will be a bit of an unpleasant day in Winnipeg today as breezy northerly winds combine with light snow and cooler temperatures. Nicer weather is on the way soon, though, with plenty of sun and warming temperatures through the weekend.
Moderate northerly winds will develop over the Red River Valley for Friday afternoon.
Winnipeg will find itself on the back side of a rather potent low pressure system moving from the United States into Ontario today. The region will see breezy northerly winds up to 40 gusting 60 km/h today, driven by the passing low and the approach of an Arctic high from the northwest. Along with that, a weak inverted trough slumping southwards will bring some light snow to the region. These two things will combine to produce some blowing snow in the region, but will mainly be limited to outlying areas and southwards through the Red River Valley. Temperatures will struggle to reach even -10 °C today, and head back into the mid-minus teens overnight. The wind will be stronger this afternoon, then ease overnight.
Skies will clear for Saturday, leaving behind sunny skies for the weekend. Temperatures will climb into the -5 to -10 °C range on Saturday and then into -5 to 0 °C range on Sunday. Overnight lows will sit in the -10 to -15 °C range. Of note, though, is that with full sunshine in mid-March, areas that aren’t just barren snow-covered fields will definitely see temperatures higher than this. It won’t be surprising for many parts of the city to see temperatures in the -5 to 0 °C range this weekend and to see plenty of melting despite the sub-freezing air temperatures.
Long Range Outlook
The start of next week will cool just a bit, then warm up again heading into mid-week. Some snow is possible on Wednesday as a disturbance moves through the region, but it will also likely bring a shift to daytime highs around freezing.
With no major snowfalls on the horizon and several days of sunshine ahead, it will continue to gradually feel more spring-like in Winnipeg; enjoy the pleasant weather this weekend!
Today’s seasonal daytime high in Winnipeg is +0 °C while the seasonal overnight low is -11 °C.
After a few dud events over the region snow is finally on its way to the Red River Valley, but exact amounts are still uncertain.
A stubborn Arctic High will remain entrenched over northern Manitoba as the next disturbance brings moderate easterly winds to the Red River Valley.
It’s been a complex weather situation over the Red River Valley over the past few days. The snow we earlier this week did develop as expected, and in fact, over the past few days was visible on RADAR as it streamed northwards over the region. But a stubborn Arctic High entrenched over northern Manitoba complicated things substantially.
This high was pumping copious amounts of cool, dry air into the northerly flow over the region which was pushed underneath the snow lifting northwards. This dry air ended up evaporating most of the snow before it managed to reach the surface. As a result, we saw little to no snow through the region over the past few days despite it falling a few thousand feet above ground.
This setup continues today, with cloudy skies and a slight chance of flurries. Temperatures will reach a high near -2 °C this afternoon, the d up down into the -5 to -10 °C range tonight.
The third system we talked about in our last forecast is now developing in the west and will begin bringing snow to Saskatchewan tonight and then spread across Manitoba on Saturday. The snow will begin in Winnipeg mid- to late-morning on Saturday and persist to the evening before beginning to ease. Moderate easterly winds up to 40 gusting 60 km/h will accompany the snow, producing blowing snow across the region in the afternoon.
There is still some uncertainty with snowfall totals. Like with the previous systems, weather models have struggled to fully capture the impact of the Arctic High entrenched over the Northern Prairies. As a result, model runs have been slowly shifting the expected track of this system further south over the past few days, reducing the amount of snow over many parts of the Prairies. But the models do seem to be stabilizing their tracks, and it looks reasonable at this point that Winnipeg will likely see 5 to 10 cm of snow with this system.
The ECMWF snowfall forecasts have begun to stabilize with 5 to 10 cm of snow for Winnipeg and higher amounts to the south and west.
Further south, snowfall totals could rise quickly, especially along the western escarpment where snow will be enhanced by the persistent easterly winds. Heading southwards through the Red River Valley, accumulations will likely increase into the 10 to 20 cm range. The higher snowfall amounts coupled with the strong winds could result in very poor travel conditions, particularly near the International Border, on Saturday afternoon.
Temperatures will hover around -6 °C on Saturday, then dip down close to -10 °C on Saturday night.
Some light snow will linger through Saturday night and then taper off on Sunday. Temperatures will linger in the -5 to -10 °C range through the day under cloudy skies, then dip to a low in the -15 to -20 °C range overnight as skies clear.
Long Range Outlook
In the wake of this system, skies should clear as cooler air floods into the region. Seasonably cool temperatures will move into the region to start the week with highs generally in the -5 to -10 °C range.
Another disturbance will move into the region mid-week and could bring some more accumulating snow to the area along with warmer seasonal temperatures.
Today’s seasonal daytime high in Winnipeg is -2 °C while the seasonal overnight low is -12 °C.
