An active weather system moving through the southern Prairies Monday is expected to bring a mix of heavy rain, gusty winds, and possible thunderstorms — and in some areas, the potential for severe weather.
A low-pressure system sitting near the Alberta-Saskatchewan border Monday morning is expected to track northeast and reach the Battlefords region by late evening. As it moves, a cold front will sag through southern Alberta, while a warm front stretches across the northern grainbelt into Manitoba’s Interlake region.
That combination of warm and cold air, along with upper-level winds, will trigger widespread showers and storms through the day. In east-central Saskatchewan, the conditions are ripe for storm development Monday afternoon and evening. While any tornado threat remains low, forecasters say it’s not zero, especially in areas east of Highway 11 toward the Manitoba border.
More likely is a line of strong thunderstorms forming along the frontal boundary, pushing into western Manitoba Monday evening. That system could bring damaging wind gusts reaching 90 km/h, as well as heavy rain and hail in some locations.
Further north and west — including parts of west-central Saskatchewan — steady rainfall is expected throughout the day and night. Localized rainfall totals could exceed 25 mm by early Tuesday morning. That band of rain will shift into northern Manitoba Monday night, with areas like Lynn Lake and Churchill seeing between 10 and 20 mm by Tuesday morning.
Behind the rain, colder air is expected to spill in, and there’s a risk of freezing rain near Churchill by Tuesday.
Environment Canada advises residents across Saskatchewan and Manitoba to stay weather-aware and monitor alerts as the system moves through.
