Saturday and Sunday: Heat persists across the prairies, isolated thunderstorm risk

Isolated thunderstorms appeared in parts of the Prairies during the day on Friday. We can expect these storms to continue Friday night into early Saturday across parts of Saskatchewan and Manitoba. Heat warnings will continue across much of the prairies as we head into the weekend. Almost all major cities — including Calgary, Saskatoon, Regina and Winnipeg — are on alerts to warn residents of extreme heat and humidity. Daytime high temperatures on Saturday will climb into the 30s across the region, with temperatures looking to approach 40 in some areas, especially in Saskatchewan. Residents and visitors to the warned areas are advised to take the following precautions to protect themselves, their families and their neighbors:

Consider rescheduling outdoor activities to cooler times of the day. Take frequent breaks from the heat, spending time in cool indoor spaces where possible. Drink plenty of water and other non-alcoholic, non-caffeinated beverages to stay hydrated. Check for your children or pets before getting out of your car. Do not leave any person or pet in a closed vehicle for any length of time.

There will be a risk of thunderstorms in many areas, including the Alberta foothills and a portion of the prairies from northern Alberta to the Interlake region. People around Calgary, Edmonton, Fort McMurray and Prince Albert could experience some thunderstorms to start the weekend. Some of the storms in central Saskatchewan and Manitoba may approach severe limits. While the storm risk is isolated, any stronger storms that form in these areas could produce strong winds and large hail.
