After a couple cooler and unsettled days, sunnier skies and warmer weather will build back into southern Manitoba this weekend.

RDPS 2m Temperature Forecast valid 21Z Saturday September 7, 2024
Significantly warmer temperatures will begin to spread east across the Prairies on Saturday.

To wrap up the work week, Winnipeg will start the day with mixed skies and a slight chance of showers. A weak disturbance over the region this morning will bring that chance of unsettled weather, but it will dissipate as the day wears on. Winnipeg will likely see mixed skies continue into the afternoon as temperatures climb to around 20 °C.

Temperatures will head to a low in the 5–10 °C range tonight with light winds and clear skies.

Heading into the weekend, an upper ridge will build across the Prairies, bringing heat back to the region. Southerly winds will increase into the 20–30 km/h range on Saturday with highs pushing back into the mid-20s. The city should see partly cloudy to mixed skies through much of Saturday, but no chance of rain.

Winds will ease on Saturday night as skies clear and temperatures head down into the low teens.

On Sunday, temperatures will climb back up into the upper 20s with light winds and sunny skies. It will cool down overnight back to the low teens again.

Long Range Outlook

The upper ridge will continue to pump heat into the region to start next week, sending daytime highs close to around 30 °C. Much of next week will bring seasonably hot conditions with highs mainly in the 25–30 °C range.

There’s little to no chance of rain until the second half of the week, but the most likely chance for rain will develop towards the weekend when the upper ridge begins to break down and cooler temperatures begin to push back into southern Manitoba.

Today’s seasonal daytime high in Winnipeg is 20 °C while the seasonal overnight low is 8 °C.

Hot Weather Before a Big Cool-Down

There will be a couple more hot days in Winnipeg before a cold front sweeps through the province and ushers in much cooler conditions for a few days.

Southern Manitoba will have another couple days of warm weather before a strong cold front pushes through the region.

A weak upper ridge building east across the Prairies will bring warm weather to southern Manitoba over the next couple days. In Winnipeg, temperatures will climb to a sunny high near 30 °C today and into the mid-20s on Wednesday. Southerly winds of 30–40 km/h will build into the region today and ease into the 20–30 km/h range tonight. Temperatures will dip down to an overnight low in the upper teens tonight.

A trough of low pressure will move through on Wednesday morning, bringing mixed skies and lighter winds. Skies will clear through the day with northwest winds up to 30 km/h developing for the afternoon. There may end up being a low chance of isolated afternoon showers or thunderstorms, but it does not look likely right now.

A more substantial pattern change will occur on Wednesday night, marked by a strong cold front that pushes into the region overnight. This will bring northerly winds up to 40 gusting 60 km/h to the region as a colder air mass moves in. The cold front will bring a chance of showers to the region on Wednesday night into Thursday morning. Temperatures will head to a low in the low teens on Wednesday night.

Much cooler conditions will move into the region on Thursday, marked by an Arctic high building across the Prairies. Temperatures will struggle back to the mid-teens on Thursday with cloud cover breaking up through the day.

Temperatures will head down into the mid-single digits on Thursday night with clearing skies and easing winds.

Long Range Outlook

Friday will bring more cool weather to the region with sunny skies and a high in the upper teens. It iwll be another cool night with lows in the mid-single digits on Friday

Light southerly winds will redevelop on the weekend, marking the start of a gradual trend towards warmer weather. By next week, the region will be back to daytime highs in the mid- to upper 20s and overnight lows in the low teens.

Today’s seasonal daytime high in Winnipeg is 21 °C while the seasonal overnight low is 9 °C.

Weather Settling Through the Weekend in Southern Manitoba

Seasonal temperatures will return to southern Manitoba as a ridge of high pressure begins to build into the region from the west.

RDPS 10m Wind Forecast valid 21Z Saturday August 31, 2024
A passing disturbance will usher in moderate northwest winds across southern Manitoba on Saturday.

Warmer temperatures return to Winnipeg and area today as westerly winds continue across the region. Daytime highs will climb back into the mid-20s today as warmer weather bounces back into the region behind the low that moved through yesterday. The wind will be persistent out of the west today near 30 gusting 50 km/h, then ease in the evening. The entire region will see plenty of sunshine today.

The low tonight will dip down into the low teens.

On Saturday, an upper-level disturbance will rotate through the region, bringing mixed skies to the region and a chance of showers. The rain looks to mainly stay north of Winnipeg with decreasing likelihood further south. As the disturbance passes through, it will usher in moderate northwest winds up to 40 gusting 60 km/h across the Red River Valley. This will keep daytime highs near-seasonal in the low 20s.

There is a chance with both the tail end of the westerlies today and the northwesterlies on Saturday that smoke may move into the Red River Valley. It’s unclear how thick any of those smoke plumes would be, though it looks more likely that Saturday would bring a more noticeable smoke plume into the region for a time.

The winds will taper off on Saturday evening with clearing skies and an overnight low that dips into the upper single digits.

A broad ridge of high pressure will move across southern Manitoba on Sunday, bringing light winds, clear skies, and seasonal highs in the low 20s.

Long Range Outlook

A southerly flow will redevelop early next week and bring warmer weather back into the region with highs climbing back into the upper 20s. It does not look like there will be an appreciable chance of rain in the first half of the week, but the chance for mid-week thunderstorms can’t be ruled out at this point.

Enjoy the weekend!

Today’s seasonal daytime high in Winnipeg is 22 °C while the seasonal overnight low is 10 °C.

Tuesday’s Cool, Showery End Leads to Warmer Weather

One last band of showers will move through on Tuesday evening, capping off a cool June day. Fortunately, warmer weather will return for the rest of the week.

RDPS 2m Temperature Forecast valid 21Z Thursday June 20, 2024
Despite the cooler Tuesday, early-summer warmth will return for the second half of the week.

Another upper-level disturbance will cross southern Manitoba later today and bring another wave of showers across the Red River Valley. This will cap off a day where temperatures struggle to get past the mid-teens as northerly winds and cloudy skies stay entrenched over the area.

Fortunately the winds will ease tonight with clearing skies as a broad area of high pressure spreads east across the Prairies. Temperatures will dip down into the 5–10 °C range once the showers clear out.

For Wednesday and Thursday, more pleasant conditions will return as a west-southwest flow redevelops across the region. Daytime highs will climb into the low 20s on Wednesday, then into the mid-20s for Thursday. Winds will pick up out of the west into the 20–30 km/h range on Wednesday, ease, then pick up out of the south into the 20–30 km/h range on Thursday.

Both days will bring a slight chance of showers or thunderstorms to the region, but they will likely be focused along a west-east trough line that will likely set up from western Manitoba across the southern Interlake region. It’s unlikely that Winnipeg will see any of that activity and both days should be pleasant in the city.

Long Range Outlook

Looking further ahead, cloudier skies will likely return to the region on Friday. A deep upper trough developing over western North America will support the development of a low pressure system over the American Plains that will then lift northeast later Friday into the weekend.

This system would likely bring a wave of thunderstorms and showers to southern Manitoba on Friday night into Saturday, with the worst weather ending Saturday morning and cooler, showery conditions possible afterwards.

Daytime highs would likely sit in the mid-20s on Friday, drop to around 20 °C on Saturday, then bounce back up to the mid-20s on Sunday. This system could produce another notable rainfall across southern Manitoba with localized accumulations of 30 to 60 mm possible.

Sunshine should return on Sunday, making for a nice end the weekend!

Today’s seasonal daytime high in Winnipeg is 24 °C while the seasonal overnight low is 11 °C.
