Another day, another possibility of bad weather for parts of the Prades. The stubborn, stormy pattern is in place due to an unstable air mass, a top-level locking pattern, and a system. On Sunday, we will see the threat of severe storms like bubbles in parts of southern Saskatchewan and Alberta, although there is a less powerful risk in southern Manitoba. Learn more about the weather, storm hazards and what to expect this week, below.

SUNDAY: THE THREAT OF STRONG STORMS RISES BUBBLES AGAIN IN PARTS OF THE PREY
The unstable air flowing over the southern prairies will lead to another possibility of storms in 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 top-level blocking pattern that has fitted into western Canada. This atmospheric block is not only responsible for the storms that are spreading through the Prades this long weekend, but it is also why they have avoided extreme heat lately.

Any severe storm that starts will spread, but it could cause heavy hail, heavy rain and strong gusts of wind.
Rainfall through Wednesday will be about 10-30 mm in the southern half of the prairies, although it is likely the highest amounts in storms, with more intense totals likely in the foothills of Alberta.
Some areas could see 50mm of rain until Wednesday.
Beyond the weekend, warmer weather will begin to rise across the region next week as the lockout pattern breaks. We will see a stretch of days with high temperatures between the middle and upper 20s, with the potential for humidex temperatures and values at 30 low in the southern regions.
Extreme heat is expected to remain south of the border during this first full week of July.
