The work week will end on a cold note as cloudy skies bring a chance of flurries to Winnipeg, but temperatures will quickly rebound to beautiful spring warmth.

RDPS 2m Temperature Forecast valid 00Z Sunday April 20, 2025
Pleasant spring weather will be in place for the Winnipeg Whiteout Street Party with temperatures near 10 °C by 6 PM on Saturday.

The cooler weather has arrived back in Winnipeg today with temperatures that will struggle back into the low single digits this afternoon. The decaying remnants of a low pressure system will slump through the area, bringing cloudy skies and a chance of snow. The main area of snow will slump through southeast Manitoba while areas further west in the Red River Valley, including Winnipeg, will see a chance of flurries that diminishes towards evening.

Winds will continue out of the north near 30 gusting 50 km/h and then ease overnight. Winnipeg should see an overnight low that dips below freezing into the -5 to 0 °C range.

On Saturday, a ridge of high pressure will move across the region bringing mainly sunny skies and light winds. Temperatures will bounce back to seasonal values with a high in the low teens and an overnight low in the 0 to +5 °C range.

Conditions on Saturday won’t be too bad for the Winnipeg Jets’ home opener against the Blues. Those of you who managed to grab tickets for the Whiteout will have temperatures near 9 or 10 °C at game start dipping down to near 5 °C by the end of the game.

By Sunday, a low pressure system crossing the southern Arctic will push a warmer air mass into the region. Under sunny skies, breezy southerly winds up to around 30 km/h will push temperatures into the 15 to 20 °C range.

Temperatures will dip down into the mid-single digits on Sunday night with partly cloudy skies.

Long Range Outlook

It looks like Monday will bring more beautiful spring weather to the region with highs in the upper teens and mixed skies.

After that, the weather may turn unsettled for Tuesday with temperatures returning to seasonal values as rain pushes through the region. After a cool day or two behind that, temperatures look to return to near-seasonal values with variable cloudiness.

Today’s seasonal daytime high in Winnipeg is 11 °C while the seasonal overnight low is -1 °C.

After a Sunny Tuesday, Cloudier and Warmer Weather Moves In

Winnipeg will see sunny skies and seasonably cool temperatures today, but another low crossing the Prairies will bring cloudier and warmer weather to the region mid-week.

RDPS 2m Temperature Forecast valid 21Z Wednesday April 16, 2025
A low pressure system crossing Saskatchewan will bring warmer weather to Winnipeg on Wednesday.

For today, skies will gradually clear as a ridge of high pressure shifts east of the Red River Valley. Winnipeg should see morning sunny breaks give way to mainly sunny skies this afternoon. Winds will be light through the day as temperatures climb into the upper single digits this afternoon. Heading into the evening, a low pressure system moving across Saskatchewan will push a warm front into southern Manitoba tonight. This will build cloud cover back into the region as temperatures head to a low near the freezing mark.

On Wednesday, the region will see mixed skies as the warm front pushes through in the morning and a cold front approaches in the evening. It will be a much warmer day with highs in the mid-teens across the region along with southerly winds of 30–40 km/h. The cold front will push a band of rain showers across the region early Wednesday night. The cloud cover will begin to break up overnight as winds ease and temperatures dip down to the low single digits.

Thursday will bring mixed skies to the region; morning cloud likely giving way to midday sun then a broader area of cloud beginning to build in from the northwest. Temperatures will climb into the 10 to 15 °C range with northwest winds picking up to around 30 km/h.

A colder air mass will settle into the region on Thursday night as temperatures dip below freezing with northwest winds continuing in the 20 to 30 km/h range.

Long Range Outlook

Friday will bring chilly weather to southern Manitoba with highs in the low single digits and cloudy skies. After another cool night on Friday night, seasonal temperatures will build back into the region for Saturday.

Saturday and Sunday should both bring pleasant conditions to Winnipeg with highs in the mid-teens. Conditions for next week are less clear; some weather models suggest a prolonged stretch of mild weather, while others suggest a slow-moving low pressure system lifting north that could bring a few days of cloudier weather with chances for rain.

Today’s seasonal daytime high in Winnipeg is 10 °C while the seasonal overnight low is -2 °C.

Beautiful Spring Conditions Ahead

Winnipeg will see a couple beautiful days before seasonal temperatures return to end the weekend.

RDPS 2m Temperature Forecast valid 21Z Saturday April 12, 2025
Mild temperatures will spread across the southern Prairies to end the week.

The upper ridge we talked about on Monday has arrived, and temperatures across southern Manitoba are warming up. The region will see breezy southerly winds today up into the 30 to 40 km/h range with mainly sunny skies. Temperatures across southern Manitoba will be much warmer today, with highs in the 15 to 20 °C range in the Red River Valley climbing into the low 20s over the southwest corner of the province. Highs will be cooler wherever lingering snowpack remains, but with dew point values above zero, that snow will be melting quickly.

Temperatures will dip down into the 5 to 10 °C range tonight in Winnipeg.

Saturday will be even more pleasant in Winnipeg with daytime highs again climbing into the 15 to 20 °C range with partly cloudy skies. Winds will be light, making for an even nicer afternoon to spend outside than today.

Temperatures will dip down back down into the 0 to +5 °C range on Saturday night with increasing cloudiness.

For Sunday, the big question has been whether Winnipeg would see no precipitation or a lot of precipitation. Weather models have flip flopped as the week progressed, but are finally beginning to hone in on an agreement.

The weather set-up is a complicated one. From the west, a low pressure system will leave southern Alberta and push across southern Saskatchewan beginning Saturday night. From the south, a Colorado Low will form and begin to eject northeast across the American Plains at the same time. The interplay between these two systems is the crux of the weather forecast, and it’s looking more and more likely that most of the system will bypass the Winnipeg area. As the Colorado Low lifts towards Minnesota, the Saskatchewan system will dig south and begin to merge with the CO Low. This will drag the precipitation from Saskatchewan into the Dakotas, while the main precipitation from the CO Low pushes towards NW Ontario and the Great Lakes.

There is a chance that Winnipeg may see a few rain showers or flurries later in the day on Sunday, but at this point no accumulating precipitation looks likely. Much of southern Manitoba will likely avoid most of the precipitation as it falls in Saskatchewan, the Dakotas, and Ontario instead.

Otherwise, temperatures will be seasonably cool on Sunday with a high in the 5 to 10 °C range with northerly winds of 20 to 30 km/h. Skies will stay cloudy into Monday with a low near the freezing mark on Sunday night.

Long Range Outlook

Looking ahead, Monday will bring cloudy and cool conditions again with a slight chance of a rain showers in the afternoon, then the region will see improvement with sunshine and near-seasonal temperatures on Tuesday.

Much of the week looks to bring mixed conditions with a couple nicer days and a couple days with a chance of rain or flurries. By the weekend, it looks like another warm-up with potential highs in the mid- to upper-teens will arrive.

Today’s seasonal daytime high in Winnipeg is 9 °C while the seasonal overnight low is -2 °C.

Gradually Warming up in Winnipeg

Brad Leave a comment

Temperatures will gradually warm through the week in Winnipeg, bringing beautiful spring warmth to the region by week’s end.

RDPS 2m Temperature Forecast valid 21Z Thursday April 10, 2025
A building upper ridge will bring warm weather to western Canada this week, gradually pushing it east into southern Manitoba.

Sorry about the delay in posting; life has been busy and we’ll go with better late than never!

Looking ahead through the rest of the work week, the weather in Winnipeg will see a distinct warming trend as an upper ridge builds over western North America. Before that warmer weather gets to southern Manitoba, though, a weak disturbance will move through the region.

This disturbance will push cloud cover into the region overnight as temperatures dip down to a low near the freezing mark. Light snow is possible by Wednesday morning. Periods of light snow will likely transition to a few rain showers through the day on Wednesday as temperatures climb up to a high near 5 °C. Winds won’t be too much of an issue, climbing to around 20 km/h out of the southeast for the afternoon.

Skies will stay cloudy on Wednesday night as the winds taper off. Temperatures will head down to a low near the freezing mark.

On Thursday, a surface high pressure will build into the province as the upper ridge begins to amplify over western Canada. Cloudy skies will gradually break up through the day with clearing pushing into the region by the evening. Winds will stay light as temperatures climb to a high in the 5 to 10 °C range. Temperatures will dip down into the -5 to 0 °C range overnight under clear skies.

Long Range Outlook

Friday will bring mixed skies to the region as temperatures climb into the mid-teens. The warmth will come with breezy southerlies up to around 40 km/h that gradually taper off on Friday night. Temperatures will likely dip down into the 5 to 10 °C range on Friday night.

There’s more uncertainty in the weather heading into the weekend. A potent low pressure system will develop in the United States push northeast, but it’s unclear if it will end up affecting southern Manitoba or track further east into NW Ontario. It has the potential to bring significant precipitation to the region, but there’s a wide range of solutions that change day by day.

It does look likely that Winnipeg should see a high in the teens again on Saturday, then cool into the single digits for Sunday. There may be rain or snow beginning on Sunday, but that will be dependent on the track of the system south of the border. We’ll keep track of this system’s development through the week and have more to say on Friday.

Until then, enjoy the warmth heading our way!

Today’s seasonal daytime high in Winnipeg is 8 °C while the seasonal overnight low is -3 °C.
