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

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

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.

Seasonably Cool Weather Ahead This Week

Temperatures will stay seasonably cool this week in Winnipeg as a couple glancing systems bring chances of light snow.

RPDS 2m Temperature Forecast valid 18Z Thursday April 3, 2025
Seasonal temperatures will build into Winnipeg by Thursday, but a weak cold front will sweep through on Thursday evening.

After a cool start to the morning, breezy southeast winds develop as a warm front pushes north towards southern Manitoba. Temperatures will climb to a high near +2 °C this afternoon with southeast winds of 30–40 km/h gusting up to around 50 km/h. Skies will cloud over through the afternoon; this cloud cover will stick around into the night with a chance of flurries as the warm front moves through. Temperatures will dip down into the -5 to 0 °C range with southeast winds continuing near 20 km/h.

Wednesday will bring cloudy skies to the region as a strong low pressure system moves from the American Plains towards Lake Superior. Temperatures will climb to a high near +3 °C in Winnipeg with easterly winds near 20 km/h swinging around to the northwest through the day. There is a chance of light snow, but it will be contingent on the broader area of snow associated with the low to the south backing northwest all the way through the Red River Valley to Winnipeg. This is an uncertain proposition at this point, and even if the snow does make it this far north, accumulations should be minimal.

Temperatures will dip to the cold side of freezing on Wednesday night with skies staying cloudy.

The sun should appear again later Thursday as the low pressure system glancing by the region shifts off into eastern Canada. Temperatures should pop up to around 5 °C in the afternoon with northwest winds of 20–30 km/h. More cloud will move in later Thursday evening, though, as a cold front swings into the area from the northwest. Temperatures will dip into the -5 to 0 °C range on Thursday night with a chance of flurries.

Long Range Outlook

The cloud and chance of flurries will linger into Friday with temperatures gradually climbing back to the warm side of freezing. Clearing skies on Friday night coupled with a cooler air mass will likely send temperatures back down to around -10 °C by Saturday morning.

The weekend will bring variable cloudiness and cool weather to the Winnipeg area. Daytime highs will dip down to freezing by Sunday with chilly overnight lows.

Today’s seasonal daytime high in Winnipeg is 5 °C while the seasonal overnight low is -6 °C.

Springtime Roller Coaster Sets up Over Southern Manitoba

Temperatures will be all over the place this week as a series of low pressure systems draw warmth north and drive cold air south.

RDPS 2m Temperature Forecast valid 12Z Tuesday March 11, 2025
An Arctic high will bring cold temperatures to southern Manitoba on Tuesday morning.

It’ll be a frigid start to the week with temperatures down into the -20s across southern Manitoba this morning. An Arctic air mass settled into the region overnight behind the cold front of the clipper system that brought a fresh coat of snow to the region yesterday. Fortunately, the cold won’t be here for long as the Arctic high responsible for it quickly shifts towards eastern Canada.

Temperatures will rebound back into the -10 to -5 °C range this afternoon with southerly winds picking up into the 20 to 30 km/h range. Much of the day should bring sunshine, but skies will cloud over in the evening. Another low pressure system will slump through the province into North Dakota tonight. It will keep temperatures from dropping much overnight and bring another dusting of snow to the region. The snow should begin sometime after supper and taper off overnight. Snowfall amounts by Wednesday morning should be less than a centimetre or two.

The weather for the rest of the work week will be defined by two features: an upper ridge building into the Prairies and a deepening upper trough on the west coast.

The building upper ridge will bring milder temperatures back to the region with daytime highs climbing to around the +5 °C mark on Wednesday. As a bonus, Wednesday should bring sunny skies with southwest winds in the 15 to 25 km/h range.

By Wednesday evening, a well-developed warm front will lie draped from the southwestern Prairies into North Dakota. A weak impulse will track along it on Wednesday night, bringing more cloud and light snow. There will be a risk of freezing rain overnight as warm air continues to stream north over the warm front through the night. At this point, it is not expected to be a widespread concern but we could see slippery areas on Thursday morning from overnight freezing rain.

Temperatures will dip down into the -5 to 0 °C range on Wednesday night with northeast winds picking up into the 20 to 30 km/h range.

Thursday could bring warm weather to southern Manitoba.

Skies will clear out on Thursday as the deepening upper trough over the west coast begins to drive the development of a large low pressure system in the United States. The temperature forecast is tricky for the day as there are disagreements as to whether the warm front over the region will stay roughly in place or lift north. If winds stay northeast, daytime highs will likely reach a degree or two above 0 °C. If the region can switch to easterly or southeasterly winds, then much warmer weather is possible.

Long Range Outlook

Heading into the end of the week, the broad story is clear, but the details are impossible to discern at this point. As the upper trough begins to dig east towards the American Plains, a potent Colorado Low will develop and begin to lift northeast on Friday. A warm front will be driven northeast through southern Manitoba as warm air surges north. Daytime highs of 15 to 20 °C will be possible over northern Minnesota, but temperatures in the Red River Valley will likely reach the 5 to 10 °C range. As the warm air pushes north, cold air will dig in from the northwest; heading into western and southwestern Manitoba, daytime highs may not even break the freezing mark.

This system will spread multiple waves of precipitation north over a couple days, and almost anything could be possible: heavy rain showers, freezing rain, broad areas of rain, snow, and ice pellets. This system will bring strong northerly winds on its western flank with much colder weather digging into the region later on Saturday.

At this point, it looks like much of this system’s precipitation will track east of the Red River Valley but forecasting the track of Colorado Lows more than a few days out can be a futile effort. There is the chance that this system’s track could shift east and end up missing our region…or that its track shifts west and the Red River Valley experiences the brunt of this system.

Be prepared for the potential for a major storm this weekend with all sorts of wintery weather possible, and hope for the best!

Colder weather will settle into the region for Sunday as the temperature drops into the minus teens on Saturday night and rebounds towards the -10 to -5 °C range.

Warmer weather will build back in for next week with daytime highs climbing back above freezing.

Today’s seasonal daytime high in Winnipeg is -2 °C while the seasonal overnight low is -13 °C.
