Quiet and Mild Weather Ahead for the Weekend

The weather will quiet down across southern Manitoba this weekend with mild temperatures and mostly cloudy conditions.

RDPS 2m Temperature Forecast valid 21Z Saturday December 31, 2022
It will be a mild end to 2022 with daytime highs climbing into the -5 to -10 °C across southern Manitoba on Saturday.

A slack westerly flow aloft will be the main guide for the weather over the next few days. This upper-level pattern will keep the Arctic air at bay up north and allow daytime highs to reach relatively mild values in the -5 to -10 °C range. A weak ridge of high pressure moving through the area today will bring some sun to the region, but cloudier skies will return for the weekend.

There won’t be any notable snowfalls in the coming days, but a few flakes can’t be ruled out when the cloud rolls in for the weekend.

Overnight lows will tend to sit in the -10 to -15 °C range, but will drop closer to -20 °C if, or when, any clear patches are able to form.

Long Range Outlook

It will largely be much of the same next week, though some cooler near-seasonal temperatures may arrive mid-week with a trend towards sunnier conditions. It looks like more warmth and cloudy skies will return for next weekend. No significant snowfall is in the forecast.

Today’s seasonal daytime high in Winnipeg is -13 °C while the seasonal overnight low is -23 °C.

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.

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.

RDPS 2m Temperature Forecast valid 21Z Thursday November 24, 2022
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.

RDPS 2m Temperature Forecast valid 09Z Sunday November 13, 2022
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.
