Winnipeg will see cooler conditions as unsettled weather continues over the next couple days.

Cool and cloudy conditions will continue in Winnipeg today. A low pressure system lifting northeastwards out of the Dakotas will spread cloud and showers across the Red River Valley through the day. Many areas in the Red River Valley will likely see showers through the day today with accumulations of 10 to 20 mm. Areas of more intense convection with isolated thunderstorms may develop with this system as well, producing localized rainfall accumulations in excess of 30 mm.

The cloudy, wet conditions will keep temperatures cool with a high near 20°C. It will also be a windy afternoon with northwest winds strengthening to 30–40 km/h. Winds will taper off this evening with temperatures dipping to a low near 11°C.

Saturday will bring mixed skies to the region with west-northwest winds of 20–30 km/h.
