Renewed risk for storms builds in Alberta on Sunday
A warm and stormy weekend continues on the Prairies as a renewed threat for thunderstorms bubbles for parts of the region on Sunday.
Scattered storms built in the heat of the day on Saturday, especially in southern Manitoba where afternoon temperatures pushed close to the 30-degree mark.
Stay close to safe shelter on Sunday if you’ve got outdoor plans when storms are in the forecast. Plan ahead and be weather-aware this weekend.

Storm threat centres over Alberta on Sunday
The risk for thunderstorms will fall mostly over Alberta during the day on Sunday.
An approaching upper-level disturbance and converging winds at the foothills will work together to spark thunderstorms during the afternoon hours, potentially reaching severe levels in some areas.
The strongest storms that bubble up on Sunday could produce large hail, gusty winds, heavy rain, and frequent lightning.
Upper-level winds will likely push storms toward the southeast, bringing a storm risk into Calgary by Sunday evening.
Forecasters are also watching rain building into parts of southern Manitoba through Sunday and Monday.
All of this additional rainfall is good news for the region’s long-running drought as we inch closer to the heart of wildfire season. The latest update of the drought monitor continues to show the vast majority of the Prairies mired in a moderate drought or worse as of April 30.
This update doesn’t include the rain we saw during the first week of May, so there’s likely been some further improvement across southern Alberta and southern Saskatchewan.
Severe drought remains widespread throughout the northern Prairies, with some relief possibly in sight by the end of next week.
