Winnipeg will see a gorgeous Canada Day with plenty of sunshine and warm temperatures.
Before that cooler air mass arrives, though, Winnipeg will be celebrating Canada Day with another beautiful day! Temperatures will climb up to around 29°C today with a much lighter wind than yesterday. A weak high passing along the U.S. border will keep winds calm this morning, then they’ll pick up to around 20 km/h out of the southwest this afternoon. The winds will stay southerly at 10 to 20 km/h tonight as temperatures dip to a low near 15°C.
The city will have a chance of a thunderstorm late overnight into early Tuesday morning. It looks unlikely right now, but the risk is non-zero. A convective complex will develop along a cold front in southern Saskatchewan today and push eastwards towards the Manitoba border. The most likely scenario is that these storms will dissipate near the border as the upper-level support collapses overnight. If that doesn’t happen, though, there’s a chance that the storms could make it this far, giving Winnipeg a thunderstorm late overnight or early Tuesday morning.
The cold front will slow down as it moves across the Red River Valley, bringing partly cloudy skies and a continued chance of showers or thunderstorms until it moves through in the afternoon. Temperatures will climb to a high near 23°C with 20 km/h southwesterly winds shifting northwest behind the cold front. The winds will diminish in the evening, then clouds will build into the region overnight. Winnipeg should see a low near 13°C, although it could be a tad warmer if the clouds move in earlier.
Wednesday will bring a mix of sun and cloud as a warm front pushes back northwards. A few showers or thunderstorms look likely over the southern Red River Valley, but indications are that Winnipeg will remain north of the precipitation. Temperatures will climb to a high near 23°C with southwesterly winds of 10 to 20 km/h. Wednesday night looks to bring partly cloudy skies and a low near 13°C to the city.
Long Range Outlook
The remainder of the work week is forecast to bring variable cloudiness with near-seasonal temperatures. The chance for rain may increase heading into the weekend, but confidence is low. Lots of generally pleasant summer weather ahead!
Today’s seasonal daytime high in Winnipeg is 25°C while the seasonal overnight low is 13°C.
