On Thursday, there is another large region under the risk for scattered storms, with the greatest chances for severe thunderstorms to develop over parts of Saskatchewan and Manitoba. Cooler weather will spread east across the Prairies through the weekend, as below seasonal temperatures dominate much of next week as well. More on the storm timing and impacts, below.

“From Calgary to just south of Edmonton, there is the risk for storms that could produce strong wind gusts and large hail, up to nickel and loonie size,” says Matt Grinter, a meteorologist at The Weather Network.

These storms will develop through the evening and continue into the early overnight hours as well.

In eastern Saskatchewan and western Manitoba, there’s also the threat for stronger storms to develop, with once again, powerful wind gusts and large hail on the table.

“Hail in these regions may be slightly larger with loonie and even up to golf ball-sized hail possible,” Grinter adds. “With this area, there is the chance for some rotating storms as well.”
