After a streak of cloudy and wet weather which brought the most significant multi-day rainfall totals of 2017 to Winnipeg, the sun is finally set to return. Winnipeg will enjoy several relatively sunny days ahead with temperatures rebounding back towards seasonal values.
After seeing 65.1 mm of rain in the past 10 days, Winnipeg is poised to enjoy a few days to finish drying out1 as fairly benign weather returns to the region. Today will be quite a pleasant day; skies will start off sunny this morning and become more mixed in the afternoon with temperatures climbing to an above-seasonal high near 18°C. Winds will be light until a weak cold front passes through this afternoon, after which they’ll switch to the northwest at around 20-30 km/h for a few hours before diminishing near sunset. Skies will remain partly cloudy to mixed overnight with temperatures dipping to a low near 7°C.
Thursday’s main driver for the weather will be a large ridge of high pressure building southwards out of the Arctic. As it pushes towards the southern Manitoba, it will keep winds out of the north at 20-30 km/h with slightly cooler temperatures in place as highs climb to a seasonal 16°C. Skies will remain partly cloudy much of the day. Thursday night will be a cool one as the high pressure centre moves across Southern Manitoba. Temperatures will dip to a low near 2°C with patchy frost an outside chance, but it looks relatively likely (for now) that extensive fog development may occur through the night, which would likely keep lows above the freezing mark. That said, it’ll certainly be cool, so if you have temperature-sensitive plans, probably best to take care of them before Thursday night.
Friday will bring mainly sunny skies to Winnipeg & the Red River Valley, outside of any fog that may be in the region in the morning. As the high pressure system moves off to the southeast, it will bring southerly winds at around 10-20 km/h as temperatures climb to a high near 16°C again. Temperatures will dip to a low near 8°C on Friday night with winds increasing out of the south to 20-30 km/h.
Long Range
Warmer, but windy, weather will move into the Red River Valley on Saturday with daytime highs climbing towards the 20°C mark as an upper ridge pushes into the eastern Prairies. Conditions begin turning on Sunday as another significant low pressure system moves towards the region. During the day on Sunday will likely be mild, although cloudy, with breezy southeasterly winds. At some point, there will be a more organized chance for rain; likely on Sunday night into Monday morning, but it could easily shift by 12 hours between now and then.
The work week will start off with seasonal temperatures and some lingering unsettled weather until things clear up mid-week again.
Winnipeg’s seasonal daytime high is currently 15°C while the seasonal overnight low is 4°C.
