The prairies will cool off this weekend after some daytime temperature records were broken in parts of the region this week. Along with that will come a multi-day storm threat thanks to a cold front moving through the region. Saturday will see the severe potential spread across all three provinces and northwestern Ontario, before narrowing down to the eastern Prairies on Sunday.

This weekend: A continued risk of a thunderstorm with a threat of wind and hail
A cold front will move north to south across Alberta and Saskatchewan on Saturday, possibly helping to produce a series of strong storms.
The system will produce showers across western Alberta early Saturday morning, potentially leading to the development of scattered thunderstorms as the day progresses into the early afternoon. They may reach severe limits in eastern Alberta and southern parts of Saskatchewan and Manitoba, with the threat extending into parts of northwestern Ontario.
The main hazards in any storm that becomes strong will be heavy rain, strong wind gusts and large hail.
The front will also bring near seasonal temperatures to Alberta on Saturday, slightly cooler in the south. Only a 12-degree temperature difference between Calgary, Alta., and Saskatoon, Sask.
Meanwhile, on Sunday, the cold front will change direction over Saskatchewan and move west to east across the province and Manitoba, potentially reaching northwestern Ontario.
The severe storm threat on Sunday will be slightly minimal across the eastern prairies. Areas of central and northern Manitoba and northwestern Ontario could see strong storms bringing heavy rainfall and strong winds, but hail is also possible.
The front will bring even cooler conditions to the prairies on Sunday, with widespread temperatures in the low 20s.
Look ahead: Warmth returns, storm pattern eases
Cooler weather is due to the drop, but more heat is coming early next week. Another ridge of high pressure will dominate, pushing this low into eastern Canada. Temperatures are forecast to reach the low 30s by midweek, accompanied by some humidity.
In fact, a heat wave is expected for several days in the last days of August and early September, especially in the western and central parts of the region, where temperatures will reach the low to mid-30s.
Fairly quiet conditions are expected for most of next week.
