Winnipeg will get its first taste of summer this weekend as hot temperatures move into the region and bring a chance of showers or thunderstorms.
Today will start with lingering cloud and/or showers from a cold front that moved through overnight making its way out of the region. The rest of the morning will be sunny, then skies will become mixed for the afternoon. It won’t be as warm today as yesterday; moderate northwest winds up to 40 gusting 60 km/h will limit daytime highs in the area to around 20 °C.
The wind will quickly ease this evening, then temperatures will cool off towards 10 °C tonight. More cloud will build into the area overnight as a warm front approaches from the west. There’s a small chance of scattered showers early Saturday morning as the warm front moves through.
On Saturday, the region will see mixed skies as moderate westerly winds up to 30 gusting 50 km/h move into the region. With the warm front through, temperatures will climb into the 25 to 30 °C range; likely topping out at 26 or 27 °C. Dew points will stay in the mid to upper single digits through the day, sending relative humidity values down to the 20–30% range. The warmth, dry air, and moderate winds will increase the fire risk for the day across the region.
A cold front will slump into the region on Saturday evening and will trigger scattered showers and the risk of thunderstorms. With a dry air mass in place over the region, there will be little energy for any convection to work with. This will mean severe weather is unlikely, but strong and gusty winds are possible with any showers or thunderstorms that develop.
Temperatures will head back down to around 10 °C on Saturday night as skies clear and winds ease.
Sunday will bring more settled conditions as a ridge of high pressure moves across the province. Temperatures will climb to a high in the 15 to 20 °C range with moderate northerly winds. Skies will stay mainly sunny through the day. It will be a cool one on Sunday night as temperatures drop close to 0 °C with a risk of frost.
Long Range Outlook
Similar weather will continue on Monday in the Winnipeg area with partly cloudy skies and a high in the 15 to 20 °C range.
On Tuesday, a low pressure system is forecast to move into Manitoba, bringing several days of unsettled weather to the Winnipeg area. Showers are possible Tuesday and Wednesday, then conditions should begin to improve heading towards next weekend.
Today’s seasonal daytime high in Winnipeg is 18 °C while the seasonal overnight low is +4 °C.
