Cooler, Pleasant Weekend Ahead

Winnipeg will see seasonably cool weather right through the weekend with otherwise pleasant conditions.

A ridge of high pressure will bring sunny skies to the Red River Valley as it pushes into the province today. Winds will be breezy out of the northwest again at 30 gusting 50 km/h, keeping temperatures cool. Winnipeg should see a high near 20 °C. Skies will stay mostly clear tonight as the winds ease off and temperatures dip to a low near 7 °C.

Saturday will bring a return to seasonal temperatures for Winnipeg with a high near 22 °C. Winds will stay light as they shift to the southeast for the afternoon. Skies will start off sunny, but more cloud will build into the region through the afternoon.

On Saturday, an approaching low pressure system will bring summer heat to southern Saskatchewan and southwestern Manitoba with highs of 25–30°C. Unfortunately, the Red River Valley won’t see any of that; it will drop southwards into the Dakotas as it approaches.

A disturbance passing through the region on Sunday will bring mainly cloudy skies to the city. Temperatures will reach a high near 20 °C, but a cold front sweeping through in the afternoon will usher in significant change. Winds will shift northwesterly at 20–30 km/h in the afternoon behind the front and usher in a much cooler air mass. Skies will stay mostly cloudy right through Sunday night as temperatures dip to a low near 8 °C.

While this system will spread rain across Manitoba on Sunday, it should stay well north of the city. Areas from west-central Manitoba southeastwards into the Pinawa region will likely see around 10 mm of rain through Sunday.

Long Range Outlook

Daytime highs will plummet well below seasonal values to start the week as highs struggle to climb over 10 °C. On Monday and Tuesday, a persistent north wind combined will produce lake-effect showers in the lee of both Lake Manitoba and Winnipeg. Winds will shift westerly on Wednesday, bringing an end to the lake-effect precipitation and gradually pushing temperatures back towards seasonal values.

Also on Monday, an upper-level disturbance will drop into the region. It will spread a broad area of showers that will likely move through the Red River Valley as well.

Today’s seasonal daytime high in Winnipeg is 21 °C while the seasonal overnight low is 8 °C.

Sunny and Hot Weather Ahead

An upper ridge building across the Prairies will bring sunshine and warm summer temperatures to Winnipeg this week.

The next several days will bring plenty of sun to Winnipeg with highs climbing from the mid-20s into the low 30s. Winds will be light through the first half of the week, maxing out at 15 to 25 km/h out of the south.

A warm front will push eastwards through the region Tuesday morning, bringing a few clouds and a slight chance of a shower or isolated thunderstorm. It should clear out quickly, leaving sunny skies across the region. Another chance for rain will develop on Wednesday evening as a low pressure system moves into the region. Some cloud cover will develop on Wednesday afternoon, followed by a chance of showers or thunderstorms on Wednesday night into early Thursday.

On Thursday, a ridge of high pressure will lie draped across southern Manitoba and southeastern Saskatchewan. This will bring mainly sunny skies to Winnipeg with light southerly winds.

Hot summer weather will return to the Red River Valley on Friday.

Friday will be when the hot and humid weather settles back into the region. Winnipeg will see temperatures climb to a high near 32 °C and a breezy southerly wind will draw humid conditions northwards. By the end of the day, the dewpoint is forecast to reach almost 20 °C which would make for noticeably muggy conditions.

A cold front will push eastwards across the region on Friday evening into the night. It looks likely that it will support an area of showers and thunderstorms as it moves through.

Long Range Outlook

The weekend will bring more sunshine with a return to comfortable humidity levels. Both Saturday and Sunday will see high temperatures in the upper 20s.

Today’s seasonal daytime high in Winnipeg is 26°C while the seasonal overnight low is 13°C.

Sunshine Ahead With Seasonal Temperatures

A sprawling area of high pressure will keep skies sunny in Winnipeg with highs in the mid-20s through the first half of the week.

Winnipeg will see pleasant, benign weather over the coming days as a ridge of high pressure dominates the eastern Prairies. With plenty of sunshine over the next few days, the city will see highs near of 25–27 °C and lows of 12–15 °C. Winds will be light, notable only on Tuesday when they will be out of the south near 20 km/h.
