More Unsettled Weather for Winnipeg

Winnipeg will see a couple more chances for showers or thunderstorms this week as unsettled conditions stretch to the weekend.

A low pressure system moving into the province overnight brought widespread showers and thunderstorms to the province. Any remaining activity that moved on overnight will drift off to the northeast this morning, leaving behind mixed to cloudy skies. Temperature will warm up quickly through the morning, reaching around 27 °C by midday. The warmth will be accompanied by humid conditions — dew points will climb into the upper teens — and provide a moderate amount of energy for the redevelopment of thunderstorms.
