FRIDAY: LINGERING SEVERE WEATHER THREAT IN SOUTHERN PRAIRIES
The boundary responsible for Thursday evening's severe thunderstorms in western, southern Alberta may spark more severe weather Friday, as it continues to hang around the foothills. The storms may fire up along the foothills in the afternoon and evening hours.
A low pressure in the eastern Prairies will bring the chance for severe storms in southern Manitoba and southwestern Saskatchewan. Storms may redevelop in the afternoon hours, lingering into the overnight hours as they weaken and trek into northwestern Ontario.
Any severe storms that initiate may bring heavy rainfall, small hail and strong wind gusts.
The heat will ease off somewhat in southern Saskatchewan and Manitoba, with daytime highs dropping below 30°C. Daytime highs will be again in the mid- to upper-20s in Alberta, with pockets of 30-degree temperatures in extreme southern areas and northern foothills.
SATURDAY: STORM RISK CONFINED TO ALBERTA
On Saturday, the threat for severe thunderstorms will remain in western and southern Alberta, along the foothills, in particular, thanks to the slow-moving boundary. A non-severe storm risk will shift into northwestern Ontario.
Storms could fire up in the evening hours and continue into the overnight, possibly bringing small hail, heavy rainfall and strong wind gusts.
Meanwhile, high pressure takes over in Saskatchewan and Manitoba, giving them a break from the recent stretch of severe weather and providing a pleasant Saturday.
Temperatures will remain above seasonal, with daytime highs remaining in the mid- to upper-20s in the central and southern Prairies. A slight cooldown is expected for Sunday.
Keep an eye on the forecast as the week progresses.
