Saturday, July 17th 2021, 8:58 pm - The threat for severe thunderstorms shifts largely to Manitoba on Sunday, though with a slice of it still in Saskatchewan and Alberta
There's still more severe storm risk on the Prairies ahead to close out the weekend, largely concentrated in Manitoba though Saskatchewan and Alberta aren't completely in the clear. As for temperatures, they'll remain hot for many into next week after a brief interruption. More on the continuing storm threat and the ongoing heat and temperature divide, below.
SUNDAY: SEVERE STORM POTENTIAL LINGERS, TEMPERATURES CONTINUE TO RISE
On Sunday, the same low that brought such widespread storm risk to much of the region will continue to track east across the Prairies, once again bringing the potential for severe weather.
The risk area will be very much drawn back from its Saturday peak, however – presently, the severe risk will be concentrated along a slice of the foothills of Alberta, extreme southern Saskatchewan beside the International Border, and a fair bit of southern and central Manitoba, including Winnipeg.
Any storms that do fire up look to have a start-time in the afternoon and evening hours, though may continue into the overnight in Manitoba and northwestern Ontario. The main hazards will be heavy rainfall, strong wind gusts and large hail.
NEXT WEEK: PROLONGED HEAT HANGS AROUND
A few regions will see daytime highs in the upper 20s to start next week, but the heat will reintensify quickly. Daytime highs will once again climb into the 30s, with overnight lows remaining in the upper teens or low 20s through the remainder of next week, so there won't be much nighttime relief.
In fact, many cities in the south will stay over the 30°C mark for a week straight, which is rare, and for some, overnight lows won't fall below 20°C.
Above-seasonal temperatures will eventually spread into northern communities as well. Fort McMurray, which typically sees a high temperature around 23°C this time of year, is expected to see a high of 26°C on Monday.
An impending spell of sustained high heat and little rainfall is a terrible prospect for agriculture on the Prairies, which is already suffering from the effects of the heat and dryness they’ve experienced so far this season.
