Severe storm risk persists on the Prairies, with large hail possible

It's been a stormy week on parts of the Prairies, particularly in Saskatchewan, which has seen tornado warnings on multiple days. The threat for severe weather will stick around Friday, with southern areas of the aforementioned province at greatest risk of seeing storms develop. The potential will extend into Alberta and Manitoba, as well, while B.C. may see non-severe storms that could spark new wildfires from lightning strikes. The heat has also surged back in, with warnings in place for northern Prairies, with widespread temperatures into the 30s anticipated by Saturday. The weekend will also be marked by severe storm threats on both days, as well. A closer look at the end of the week, and what to expect during the weekend beyond, below.

FRIDAY: SEVERE STORM RISK LINGERS, HEAT SETTLES IN

The threat of severe weather is staying in place Friday on parts of the Prairies, thanks to a low-pressure system that will drift towards the southern areas, bringing risk with it in the afternoon and evening hours.

The focus of the severe storm potential will be in southern Saskatchewan, but parts of northwestern and southern Alberta including the foothills, and northern and southwestern Manitoba are also at risk. The main hazards with any severe storm that develops will be heavy rain, strong wind gusts and large hail.

For more northern areas of the Prairies, temperatures remain uncomfortably hot. Friday will see temperatures in the upper 20s and low 30s across the region. Heat warnings are in place for the northern Prairies, reaching as far south as central Alberta, including the city of Edmonton. The heat will spread south and east Saturday.

SATURDAY: HEAT LOCKS IN AND SHIFTS, SEVERE THUNDERSTORM RISK FOR SOME

With the heat warnings in place, a very hot and mostly dry weekend is expected on the Prairies. On Saturday, the heat gets cranked up a bit, with daytime highs reaching the low- to mid-30s across the region. This will further worsening drought conditions for the southern Prairies, especially Manitoba.

Because of the ongoing atmospheric energy available, and a low-pressure system sweeping through, the threat for showers and thunderstorms moves northward into central and northern B.C., and central northern Alberta, as well as northern Saskatchewan on Saturday.

The potential for severe storms will be mainly focused in central and northern Alberta, though it does extend south into Calgary and west into parts of B.C. The main hazards will be heavy rain, strong wind gusts and large hail.

BEYOND: POTENTIAL FOR SEVERE WEATHER SUNDAY, SOAKING RAINS ON PRAIRIES, RELIEF IN B.C.

There will also be some temporary relief from the heat late next week and weekend for central and northern B.C., as well as coastal areas, due to an upper-level low that will bring in cooler temperatures, but remaining warm for the southern Interior.

"A very warm and dry pattern is then expected to resume for the rest of July, which is extremely concerning given that the wildfire count has already climbed over 200," adds Dr. Doug Gillham, another meteorologist at The Weather Network.

On the Prairies, Western Alberta will trend cooler on Sunday, while the severe thunderstorm threat risk will shift south including Calgary for late Sunday. The risk for severe storms will also encompass much of Saskatchewan and Manitoba. The potential will then spread east across the southern Prairies Monday and Tuesday, bringing the potential for beneficial rain for parts of the region.

Manitoba could finally see some much-needed rain on Tuesday, but not nearly as much or as widespread as what it needs. Above seasonal temperatures will dominate next week.
