—
Another day, another chance for severe weather for parts of the prairies. A persistent, stormy pattern is present due to an unstable air mass, blocking upper level pattern and system. Sunday will see the threat of severe storms increase across parts of southern Saskatchewan and Alberta, although a less severe risk exists in southern Manitoba. More on weather, storm risks and what to expect this week below.

SUNDAY: THREAT OF SEVERE STORMS INCREASES AGAIN FOR PARTS OF THE PRAIRIES
Unsettled air over the southern prairies will bring another chance for thunderstorms across the provinces on Sunday. The greatest threat of severe storms will occur in parts of southern Saskatchewan and southeastern Alberta.
The recent storm pattern is the result of a blocking upper-level pattern that has wedged itself over western Canada. This atmospheric block is not only responsible for the storms raging across the prairies this long weekend, but also the reason they’ve been avoiding extreme heat lately.

Any severe storms that develop will be scattered, but could bring large hail, heavy rain and strong wind gusts.
Precipitation by Wednesday will be around 10-30mm across the southern half of the Prairies, though higher amounts likely in thunderstorms, with heavier totals likely in the Alberta foothills.
Some areas could see 50mm of rain by Wednesday.
After the weekend next week weather will begin to warm up again in the region as the blocking pattern breaks down. We will see a series of days with high temperatures in the mid to upper 20s, with the potential for temperatures and humidity values in the low 30s in southern regions.
Extreme heat should remain south of the border during this first full week of July.
