Sunday/Monday: Storm threat covers Alberta amid high heat
The risk for thunderstorms will increase again in Alberta on Sunday for the central and southern parts of the province. The severe chance will narrow to the latter, with possible risks of strong gusty winds and large hail once again. Scattered strong thunderstorms are also possible across the foothills, with the risk of hail and strong winds extending into the Calgary metro area. As a result of the heat, copious amounts of CAPE (convective available potential energy) could fuel strong storms on Sunday. The risk of supercell formation is low but cannot be ruled out. On Monday, a boundary forming in Saskatchewan will be responsible for the thunderstorm risk in the Prairies as warm air collides with cold. Southern Manitoba and western Alberta will be areas to watch for possible severe storms. In Alberta, the storm threat will be greatly reduced, confined to the western half of the Alberta fan along the BC border. Serious potential will include areas just north of Hinton, Alta., south to Lethbridge. Calgary may see strong storms again. The potential hazards will be the same as Sundays, with strong winds and large hail with any of the scattered severe storms coming to fruition.
Heat warnings remain in effect
Meanwhile, heat warnings remain locked in Alberta, where they were issued earlier in the week. Parts of southern Saskatchewan were also added to the warnings as the heat spread east during the week.

Here are some recommendations from Environment and Climate Change Canada (ECCC) to stay safe during this season of unseasonably warm temperatures:
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.
The very warm and dry pattern across southern Alberta and southwestern Saskatchewan will ease on Tuesday, although it will still be warmer than most seasonal days this week. Be sure to check back for the latest prairie weather updates.
