Mid-Week Low Brings Warm Weather To An End

A low pressure system that will move through the region will bring an end to Winnipeg’s stretch of beautiful late-fall weather. Rain, snow, and cooler conditions are on the way.

But first, a couple more pleasant November days lie ahead for the city. Winnipeg will see plenty of sunshine over the next couple days with highs in the 8–10 °C. Winds will be breezy today out of the west at 20–30 km/h, then ease slightly for Tuesday. Overnight lows will dip to around the freezing mark.

On Wednesday, a low pressure system will move from Saskatchewan into southern Manitoba, spreading cloud and rain across the province. Most areas in the Red River Valley should see 5–10 mm of rain through the day. Winds will start out at 20–30 km/h out of the southeast, then ease to light as the low moves over the Red River Valley in the evening. Temperatures will be much cooler with a high near 3 °C.

Much of southern Manitoba will see rain on Wednesday.

Rain may become mixed with snow late in the day, then will change completely over to snow sometime overnight as temperatures drop below freezing.

Long Range Outlook

The seasons will change quickly this year as the region will look a lot more like winter by the end of Thursday. Moderate northerly winds of 30–40 km/h will develop behind the low and continue to usher cooler air into the region. Snow will continue through much of the day on Thursday with 5–10 cm accumulation likely by Thursday evening. Some periods of light snow will likely continue through Friday, and a bit of light snow may be possible with a weak low on Saturday.

Temperatures will hover near seasonal values right through the weekend with highs around the freezing mark. Overnight lows will dip into the mid-minus single digits.

Today’s seasonal daytime high in Winnipeg is +1 °C while the seasonal overnight low is -8 °C.

Mild Weather Continues Despite Unsettled Wednesday

Winnipeg will continue to see seasonably mild temperatures even as a disturbance moves through the province today.

It’s back to cloudy skies in the city today with rain lifting northwards out of the Dakotas. Period of rain will begin later this morning in Winnipeg with 5–10 mm possible by the end of the day. Heavier rain will fall to the east with 10–20 mm likely over the eastern Red River Valley into the southeastern corner of the province. Despite the rain, it will be seasonably warm today with a high near 9 °C. The breezy southeasterly winds in the area this morning will diminish through the day.

The rain will shift off to the east tonight, but skies will stay cloudy for the rest of the night. Temperatures will dip to a low near 4 °C.

RDPS 24hr. Precipitation Accumulation Forecast valid 12Z Thursday October 28, 2021
Rain will spread through much of eastern Manitoba over the next 24 hours with many areas seeing at least 5–10 mm.

Thursday will continue to be seasonably warm in Winnipeg. Temperature swill climb back to around 11 °C with northwest winds near 20 km/h. Skies will be cloudy for much of the day, but some clearing should work its way in through the afternoon. Skies should completely clear out in the evening as a ridge of high pressure moves over the region. Temperatures will dip below the freezing mark on Thursday night.

And finally, to wrap up the work week, Friday will bring beautiful late-October weather to the area. With plenty of sunshine temperatures will climb to a high near 12 °C. Winds will be breezy out of the south at 30–40 km/h, though. A few clouds will begin working into the region in the afternoon as the next low pressure system begins its approach.

Cloudier skies will move in for Friday night and Winnipeg will see a chance of showers as the low crosses the province. Temperatures will once again stay mild with a low near 5 °C.

Long Range Outlook

Behind Friday’s low, Arctic air will flood across the Prairies and usher seasonal to below-seasonal temperatures into the region. Breezy northwest winds will send temperatures into the low single digits by the end of the weekend. The surge of colder air will generate a lot of lake-effect precipitation — both rain and snow — that will affect the region for several days. The return to cooler conditions looks to continue through the rest of next week.

Today’s seasonal daytime high in Winnipeg is 6 °C while the seasonal overnight low is -3 °C.

Winnipeg To See A Windy Return to Seasonably Warm Conditions

A surge of mild Pacific air will bring pleasant fall conditions back to Winnipeg, but it will get rather windy as it does so.

It will be a beautiful start to the week for late-October in Winnipeg today. A lingering ridge of high pressure will bring the city plenty of sunshine as temperatures climb to a high near 9 °C. As the warm air slowly approaches from the west, winds will begin to pick up over the Red River Valley. Winnipeg should see southeasterlies strengthen to 30 gusting 50 km/h by the afternoon. Those winds will continue tonight as the warm air pushes east and cloudier conditions move into the region. The city will see a low near +4 °C.

The winds in the Red River Valley will ratchet up to around 50 gusting 70 km/h on Tuesday as the clouds thicken up. Temperatures will be seasonably mild with a high near 11 °C. Some rain will likely move through western Manitoba, but here in the Red River Valley it should stay dry through the day. It will be cloudy on Tuesday night in Winnipeg with a mild low near 7 °C.

Strong southeasterly winds will develop over southern Manitoba on Tuesday.

On Wednesday, an area of rain will push out of the Dakotas into southeastern Manitoba. It’s likely that a portion of the Red River Valley will get clipped by this system. Winnipeg will also see a chance of showers with this system, but with the rain mainly moving by to the east, it may be a miss or just a glancing shot. Daytime highs will again climb to around 10 °C with southerly winds of 20–30 km/h. The rain will move out evening, leaving behind gradually clearing skies and a low near +2 °C.

Long Range Outlook

Mild conditions will continue through the second half of the work week with more sunshine. Another disturbance will move through on Saturday and bring a chance of showers with it. Behind that, northwesterly winds will usher a more seasonal air mass back into the region for the following week.

Today’s seasonal daytime high in Winnipeg is 6 °C while the seasonal overnight low is -3 °C.

Warming For The Weekend

Winnipeg will see one more cool and unsettled day before warmer weather moves in for the weekend.

It will be another seasonably cool day in Winnipeg today in the wake of the low pressure system that moved through mid-week.

Skies will clear out this evening as the winds ease. Winnipeg will see a low near +1 °C.
