A Weather Moment

A cold front plowing southwards today will usher significantly cooler fall conditions into southern Manitoba.

Winnipeg will see moderate northerly winds today that usher in a seasonably cool air mass that will stick around into the weekend. Under cloudy skies, Winnipeg will see winds strengthen to 40 gusting 60 km/h today in the wake of a cold front that moved through last night. The city will see a chance of showers in the morning, but a more organized area of light rain will move through with another cold front in the afternoon. Temperatures will reach a high of near 11 °C. The wind will persist out of the north through the night near 30 km/h with a low near +2 °C.

Thursday will bring skies on the cloudier side to the city with temperatures struggling to recover much. That northerly wind will gradually ease through the wind with a high near 8 °C. A few showers will be possible in the lee of the lakes. A high will move through on Thursday night, bringing light winds, partly cloudy skies, and lows dipping just below freezing.

On Friday, a low pressure system will slide southeast through Saskatchewan into the Dakotas. As it moves through, it will spread more cloud over southern Manitoba along with light southerly winds. Temperatures will be seasonably cool again with a high near 9 °C with more showers possible in the evening and overnight as a trough moves across the region. Temperatures will dip to a low near +2 °C on Friday night.

Long Range Outlook

Cool weather will persist into Saturday with some lingering lake-effect precipitation into the afternoon hours. A bit of clearing is forecast to move in on Saturday night, but more cloud returns Sunday as a warm front pushes across the province. This will bring warmer weather back to the region with highs in the mid-teens by Monday. This seasonably warm weather should stick around for much of next week.

Today’s seasonal daytime high in Winnipeg is 15 °C while the seasonal overnight low is 3 °C.

Temperatures will briefly warm up on Tuesday before the region transitions into a much cooler pattern.

The city will see mainly cloudy skies today with a seasonably cool high near 12 °C. Winnipeg itself won’t likely see any showers, but lake-effect precipitation will be possible through much of the day in the lee of Lake Manitoba and Lake Winnipeg. Temperatures will dip to a low of only 9 °C tonight with a chance of showers as a warm front pushes through the region.

Tuesday will bring some warmer weather back to the region with a high near 18 °C in Winnipeg. There should be plenty of sun with partly cloudy skies after any lingering early-day cloud clears out. Temperatures will dip to a low near 7 °C on Tuesday night.

A cold front will usher a notable pattern change into the region on Wednesday. Cloud cover will push southwards into the Red River Valle in the morning, followed by a good chance of showers. Temperatures will climb back to a high near 12 °C. Skies will stay mostly cloudy into the night with a continued chance of showers. Temperatures will head to a low near +3 °C.

While Winnipeg will see varied conditions over the next 3 days, one thing will be constant: the wind. Each day will see northwest winds pick up in the morning into the 30–40 km/h range. While the winds may be a bit gusty today and tomorrow, Wednesday will bring the strongest winds with gusts of 60–70 km/h possible.

Long Range Outlook

The second half of the week will be quite cool with highs hovering close to 10 °C and overnight lows dipping to around or just below freezing. The city will see mixed to mostly cloudy skies right into the weekend. A return to seasonal temperatures is forecast for early next week.

Winnipeg will enjoy a couple more days of mild temperatures before a passing low brings cooler and unsettled conditions back to the area.

Today will be the warmest day in Winnipeg for what could end up being a very long time. Skies will clear out this morning then warm up to a high near 24 °C as winds pick up out of the west into the 20–30 km/h range for the afternoon. The wind will ease this evening and temperatures will head to a low near 9 °C. Another low pressure system will move towards the province tonight, pushing cloudy skies into the city by morning.

Winnipeg will see mostly cloudy skies on Saturday, but temperatures will still be seasonably mild with a high near 20 °C. Winds will pick up out of the south to around 30 km/h for the afternoon. As the low passes to the north in the afternoon, a weak cold front will sweep across the Red River Valley. This will usher in a chance of showers later in the afternoon and into the night for the region. Winds will gradually shift to the northwest overnight as temperatures head to a low near 10 °C.

Sunday will continue to bring mainly cloudy conditions to Winnipeg as another cold front pushes through the area. Northwest winds of 30 gusting 50 km/h will usher seasonal temperatures back into the region. As a result, Winnipeg will see a comparatively cool high near 15 °C.
