Unsettled Summer Weather Ahead

Brad

Winnipeg will see mild temperatures through the first half of the week, but also several chances for showers or thunderstorms.

Today will start off with a few showers as a trough of low pressure moves through the region. The rain should clear out early in the morning, leaving increasingly humid conditions as temperatures climb into the mid-20s. A cold front will push through midday, bringing breezy westerly winds of 30 gusting 50 km/h that usher in drier air and clear out any remaining clouds. Temperatures will continue to climb to about 31°C this afternoon under mainly sunny skies. The winds will ease tonight as temperatures head to a low near 16°C with increasing clouds towards morning.

Tuesday will start with a disturbance tracking along the U.S. border that will likely spread showers across southern Manitoba. There will be a chance for these showers to have a few embedded thunderstorms as well. That activity will move out through the morning, followed by mixed skies with temperatures climbing to a high near 27°C. A cool trough pushing in from the northwest through the afternoon hours will bring another risk of thunderstorms to the region late in the day. Skies should clear out overnight as temperatures dip to a low near 12°C.
