We’ll be taking a break this (chilly) week and getting some much needed R&R. Until we’re back, we encourage you to view Winnipeg’s forecast over at Environment and Climate Change Canada.
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. The cloudier conditions on Thursday night will help keep temperatures slightly warmer with a low in Winnipeg near 13 °C.
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.
More Rain on the Way
A clipper system will begin racing eastwards across the Prairies today, spreading rain into the Red River Valley.
Winnipeg will see a pleasant start to the day; with sunny skies temperatures will climb to a high near 21 °C with westerly winds near 20 km/h. Later today, a clipper low racing across Saskatchewan will spread cloud into the Red River Valley, followed by rain beginning mid- to late-afternoon. The rain will last into the evening, then ease to a few showers and end overnight. Most areas in the Red River Valley, including Winnipeg, will see 5 to 15 mm of rain, but a localized corridor of 15 to 25 mm will be possible. Temperatures will dip down to a low near 10 °C tonight with winds picking up out of the northwest.
Thursday will bring mixed skies with a chance for some lake-effect showers in the morning. Winds will be prominent through the day, sustained out of the northwest up to 40 gusting 60 km/h. It will be a cool day in the wake of Wednesday’s clipper and Winnipeg will see a high of only 17 °C. Skies will clear out in the evening as the winds gradually ease. Temperatures will then head to a low near 6 °C.
On Friday, a weak ridge of high pressure will keep skies mainly sunny with northwest winds of 20–30 km/h. Temperatures will recover slightly from Thursday as Winnipeg heads to a high near 20 °C. A bit of cloud will work into the region overnight as temperatures head to a low near 7 °C and winds ease.
Long Range Outlook
Another low pressure system will cross Manitoba this weekend, but most forecasts show the rain it will bring tracking through WestMan and the Interlake. Winnipeg will likely see mixed skies on Saturday with near-seasonal temperatures, but cloudier, cooler conditions return on Sunday. The weekend may end with a chance of showers as a cold front plunges southwards through the province.
Today’s seasonal daytime high in Winnipeg is 21 °C while the seasonal overnight low is 8 °C.
Cooler, Cloudier, and Windier Weather Ahead
Seasonably cool temperatures have arrived in Winnipeg and will stick around for the week. Alongside them, the city will see increasingly unsettled and windy coconditions.
The city will start the week with a sunny and breezy day in the wake of yesterday’s rain. Temperatures will climb to a cool high near 19 °C with breezy westerly winds of 30 gusting 50 km/h. A ridge of high pressure moving through overnight will keep skies clear but send temperatures plummeting. Winds will taper off the in the evening, then temperatures will head to a low near 6 °C in Winnipeg.
On Tuesday, a trough will swing across southern Manitoba, bringing seasonal temperatures back to the region. It will also bring plenty of cloud cover. Skies will be mostly cloudy in Winnipeg with a high near 22 °C and west-southwest winds into the 30–40 km/h range. The city will see a chance of showers in the afternoon and evening, but rain is more likely across the Interlake into the southeast corner of the province. Temperatures will dip to a low near 9 °C on Tuesday night with clearing skies and easing winds.
On Wednesday, a low pressure system will move across southern Manitoba. As it pushes east, it will spread cloud into the region as it lifts a sharp warm front north of the border. Winnipeg should see a high near 22 °C again with some rain beginning later in the afternoon. The rain will continue into the evening and then taper off overnight. This system will bring 20 to 30 mm along a narrow west-east axis that is forecast to run across the Interlake. To it south, 5 to 10 mm is possible across the Red River Valley. That said, the outcome will be sensitive to the track of the low:
- If the low tracks further north, Winnipeg may see slightly warmer temperatures and less rain.
- If the low tracks further south, temperatures would be a couple degrees colder than forecast, and rainfall accumulations could significantly increase.
Temperatures will dip to a low near 7°C on Wednesday night with winds picking up out of the northwest to 30 gusting 50 km/h.
Long Range Outlook
Seasonably cool temperatures will move into Winnipeg for the later half of the week with mostly sunny skies. Looking to the weekend, Winnipeg will see variable cloudiness with temperatures continuing on the cooler side of seasonal.
Today’s seasonal daytime high in Winnipeg is 22°C while the seasonal overnight low is 9°C.
