Colder Weather Settles Over Southern Manitoba

An Arctic high building into the Prairies will bring seasonably cold temperatures and a bit more sunshine to southern Manitoba.

RDPS 2m Temperature Forecast valid 12Z Tuesday December 20, 2022
Cold temperatures will sit entrenched across the Prairies this week.

Colder temperatures are the story this week as a lobe of the polar vortex slumps into the northern Prairies. It will bring with it a persistent northerly flow that will build an Arctic ridge across the Prairies through the week.

Disturbances grazing by the region will bring a mix of sun and cloud to the region this week, but temperatures will be uniformly cold. Daytime highs in Winnipeg will sit near the -20 °C mark through the rest of the week with overnight lows generally in the -25 to -30 °C range.  

With such cold overnight lows, its possible that the region will see extreme cold warnings at times this week for wind chill values dipping to the -40 mark.

No significant snow will fall across the region this week, but a weak disturbance passing by to the south will spread some snow across the region on Wednesday. Accumulations will be minimal with just a centimetre or two possible by the time it tapers off overnight.

Long Range Outlook

Cold conditions will continue into the Christmas weekend, but by Sunday the worst should begin to break. Heading into next week, warmer weather will move into the region along with some more light snow. 

Today’s seasonal daytime high in Winnipeg is -11 °C while the seasonal overnight low is -21 °C.

Mild Week Ahead for Winnipeg

A westerly flow aloft will bring seasonably mild temperatures to Winnipeg this week.

Mild temperatures will move into southern Manitoba this week with daytime highs climbing to near or above freezing.

The Red River Valley will get a late-November treat of mild temperatures this week as daytime highs climb back above freezing. A series of low pressure systems tracking along the northern borders of the Prairie provinces will help shunt the Polar Vortex back into the High Arctic. As it retreats, that will allow for a sustained flow of milder Pacific air to spill across the Rockies and into the Prairies.

As a result, the region will see more sun than has been around in a while with mild temperatures. Daytime highs will sit around the freezing mark or just a bit warmer with lows warming from the -5 to -10 °C range mid-week to close to freezing by the end of the week.

There won’t be much chance of snow this week; the only notable possibility looks to be on Wednesday night as a weak cold front moves through. It may bring a brief band of snow through the region with it, but accumulations look like they’d be low.

Long Range Outlook

The stretch of warmer weather will come to an end this weekend as a series of weak disturbances begin to move through, bringing cloud and light snow. Each successive impulse will gradually bring temperatures back to near-seasonal values to start next week and into seasonably cool conditions later next week.

With the cooling trend will come more cloud cover and plenty of chances for light snow.

So for now, enjoy the beautiful late-November week ahead!

Today’s seasonal daytime high in Winnipeg is -4 °C while the seasonal overnight low is -13 °C.

Winter Settles Over The Red River Valley

With the heavy snow across the region over the past 24 hours, winter has finally arrived to the Winnipeg area. Though no more snow is in the forecast, cool weather will stick around for the foreseeable future.

Much cooler weather will settle over the eastern Prairies for the weekend as an Arctic high sits over the region.

There’s a blanket of white over Winnipeg today thanks to a good 10 to 15 cm of snow that fell across the city late yesterday into the night. We had talked about the potential for more snow in our last forecast, and as we expressed some concern, the system did end up shifting a bit further north — about 50 to 75 km further — than many forecast models had predicted. That said, Winnipeg ended up getting off relatively easy; to the south and east of the city, anywhere from 15 to 25 cm fell. As a result, a marked shift in temperatures will now settle over the region as, even on sunny days, the snow reflects much of the incoming heat back where it came from.

The weather over the next few days will be fairly benign, much of anything quashed by a large Arctic ridge settling over the province. In Winnipeg, this will result in diminishing winds and seasonably cool temperatures. The city will see a high around the -5 °C mark over the next several days with lows dipping down into the mid-minus teens at night. The region will see a mix of sun and cloud over the coming days, though depending on how the air mass interacts with the still-open lakes, some cloudier periods will also be possible. If skies manage to stay clear through some of the upcoming nights, with the ground now snow-covered, overnight lows could fall closer to -20 °C through the Red River Valley.

Long Range Outlook

The cool but relatively benign weather will continue into next week, with the next notable weather system expected mid-week. The passing low could bring some light snow to the region, followed by a push of cooler temperatures into the following weekend.

Today’s seasonal daytime high in Winnipeg is -1 °C while the seasonal overnight low is -9 °C.

Mild November Weather Continues, Cooler Later This Week

Winnipeg will continue to see very mild November temperatures into mid-week, then a cold front will sweep through and bring seasonal temperatures back to the region.

RDPS 2m Temperature Forecast valid 21Z Wednesday November 2, 2022
A low pressure system will push very mild temperatures into southern Manitoba on Wednesday afternoon.

The warm weather will continue for Winnipeg as a southerly flow continues to draw mild air into the region. The skies will be partly cloudy in Winnipeg with a high in the mid-teens. As the day progresses, an upper trough will dig southwards over the Rocky Mountains. This will push more warm air northwards over Manitoba and keep overnight lows very warm (for November). Winnipeg will only dip down to around 10 °C tonight, a whole 15 °C above normal for this time of the year!

Skies should stay partly cloudy into Wednesday, but its shaping up to be a gorgeous November day. It will be a bit windy as a low pressure system developing building into SW Manitoba brings southerly winds up to 30 to 40 km/h. The upside will be the warmth, with highs climbing into the upper teens and topping out at 18 or 19 °C here in the city.

The low will pass on Wednesday night, but the cold front will stay to the west a little bit longer. While the low will bring cloud to the area, the precipitation associated this system will stay well to the west and north. Winds will shift to the west overnight with a low down into the mid-single digits.

The cold front will swing through early Thursday, shifting winds to the northwest and keeping skies cloudy for the day. Winnipeg will see temperatures recover only a few degrees with just a slight chance of a scattered shower or two. Everything should clear out on Thursday night with temperatures dropping to a near-seasonal low of -4 °C.

Long Range Outlook

Friday will bring some sunshine and near-seasonal temperatures to the region, followed by slightly warmer weather on Saturday. Things will shift beginning Sunday, though, with most weather models showing a transition to cooler weather with the first real chance of accumulating snow beginning next Monday.

Today’s seasonal daytime high in Winnipeg is +4 °C while the seasonal overnight low is -5 °C.
