On Wednesday, the severe storm risk will span a broad area across Western Canada, extending from northeastern B.C. to southern Manitoba and northwestern Ontario. The primary concern will be large hail, particularly for regions near the Alberta foothills and areas stretching eastward, including cities like Regina, Sask., and Winnipeg, Man.
Following the storms, heavy rain and much cooler, spring-like conditions are expected to end off the week, with some areas set to sit 5-10°C below seasonal as summer officially begins. Between 50-100 mm of rain could fall in some of the harder-hit regions this weekend.
Pay close attention to watches and warnings in your area as severe thunderstorms could bubble up on Wednesday.
Large hail: Severe thunderstorm threat continues over the Prairies on Wednesday
A cold front moving southward from the Arctic will confine the storm threat to the southern regions of the Prairie provinces on Wednesday.
Strong to severe thunderstorms are expected to develop along the cold front, stretching from Calgary, Alta., to Winnipeg, Man.
Large hail remains a key concern, with strong wind gusts posing an added risk, particularly for storms between Regina, Sask., and Winnipeg, Man.
While a lack of moisture will limit the potential for heavy rain, slow-moving storms near the northern foothills may still generate areas of localized rainfall.
Residents are advised to stay prepared and monitor for potential weather alerts.
Heavy rain and very cool temperatures kick off summer this weekend
Focus will shift from the storms to the incoming cooler conditions this weekend, with temperatures during the first few days of summer forecast to be 5-10°C below seasonal averages. This cool and unsettled weather pattern is then set to dominate the latter half of June.
Significant rainfall is also forecast for much of the agricultural regions this weekend, particularly in southern and central Alberta and Saskatchewan, where totals could reach 40-80+ mm, and 20-40+ mm closer to the U.S. border.
Southern Manitoba is also expected to receive substantial rainfall, with 20-40+ mm likely.
