Renewed severe storm risk sweeps across the Prairies again Sunday
Another round of storms could fire up again on Sunday on parts of the Prairies, with the risk for severe weather focused in on parts of Alberta, Saskatchewan and Manitoba
The lingering heat and muggy conditions on the Prairies will continue to fuel the risk for thunderstorms again on Sunday, with the threat area extending from Alberta east into southern Manitoba.
The chance for severe storms will be honed in on parts of Alberta and southern Saskatchewan, where large hail, strong wind gusts, torrential rainfall, and one or two tornadoes cannot be ruled out Sunday.

This week’s “ring of fire” heat ridge is responsible for the rounds of severe thunderstorms we’re experiencing. Thunderstorms tend to form and race around the northern edge of a heat dome like the one parked over the region.
Storm threat lingers on Sunday
We’ll see multiple areas at risk for storms on Sunday as the heat persists across the Prairies.
These thunderstorms could pack large hail and strong wind gusts. A small risk for tornadoes will exist, as well, but there’s some uncertainty whether or not conditions will be just right for rotation to develop.
The setup for storms on Sunday will reappear along the foothills in Alberta as a trigger and a developing front should move across southern Saskatchewan, scooping up some good moisture.
Major cities such as Calgary, Alta., Saskatoon and Regina, Sask., and Winnipeg, Man., will be under the threat of severe storms Sunday. The main hazards with any severe storm will be heavy rain, large hail and gusty winds.
The supercell potential is expected to spill into the southwestern end of Saskatchewan and Manitoba with greater uncertainty as to the location in Saskatchewan however there is better confidence for the southwestern regions of Manitoba to see some action.
The outflow from the afternoon storms will likely trigger unorganized secondary cells later on Sunday.
