Severe storm risk spills into Saturday, but cooler, fresher air is set to arrive

Friday, August 6th 2021, 8:54 pm - Though Saturday won't be storm-free, cooler and fresher air will make for a pleasant end to the weekend for some.

Severe storm risk will shift eastward across the Prairies Saturday, but the bigger story for most will be the temperatures, with cooler and fresher air spreading across the region, first for western Alberta, before spreading east through the remainder of the region next week. More on what to expect in the days ahead, below.

SATURDAY: STORM RISK, HEAT MOVES EAST

After a Friday that saw a fair bit of severe storm potential over much of Alberta, storm risk will shift Saturday to Saskatchewan and Manitoba

Presently, a section that straddles the boundary between the two provinces does carry some severe potential. The main hazards will be strong wind gusts, large hail and heavy rain.

By Saturday, western Alberta will cool off, with temperatures sitting comfortably in the low-to-mid 20s. Heat begins to infiltrate Manitoba, with daytime highs climbing into the upper 20s. The hot temperatures will remain in extreme southern Alberta and Saskatchewan, however.

SUNDAY AND BEYOND: REFRESHING TEMPERATURES ARE ON THE WAY, POTENTIAL FOR WIDESPREAD RAIN

By Sunday, parts of Alberta will be even cooler, with Edmonton and Calgary both set to fall below 20°C. Some spots near Calgary could see low temperatures in the single digits by early next week. The exception will be southern Manitoba, which may still feel a bit hot, not dropping down to seasonal until the middle of next week.

As well, forecasters are watching the potential for widespread rain for southern Alberta, and spreading east across the southern Prairies, early next week.

"Still low confidence in how much rain will fall but increasing potential for a system to develop and track south of the U.S. border. Hot weather returns to the region mid and late week," says Dr. Doug Gillham, a meteorologist at The Weather Network.
