Severe storm potential continues on the Prairies into this weekend

Hot, humid conditions will fuel additional rounds of severe thunderstorms into this weekend across parts of the Prairies

A renewed round of severe thunderstorms will bubble up across portions of the Prairies on Saturday as an active pattern continues across the region.

Severe storm risk builds again Saturday

The trough that triggered severe thunderstorms on Friday will push east into the day Saturday, renewing the potential for some rough weather in parts of Saskatchewan and Manitoba.

Numerous thunderstorms will develop through the afternoon hours, continuing into the evening before losing energy by nightfall.

Prairies storm outlook Saturday

The greatest instability will exist over western Saskatchewan, as well as tiny portions of Alberta. The strongest storms here will carry a risk for strong wind gusts, large hail, and heavy rainfall.

By late evening, the storms will congeal into clusters that will predominantly pose a threat for heavy rainfall.

A secondary area of severe weather is possible in northeastern Manitoba, where isolated to scattered storms will pop up in the afternoon and weaken by the late evening. Strong wind gusts will be the main hazard here.

Soaking rain threat develops next week

While severe thunderstorms continue to be the primary concern through the weekend, a wetter pattern is likely to develop in parts of the western Prairies early next week.

A trough settles into the region and draws moisture northward, creating the strongest signal for widespread rainfall from Sunday to Tuesday.

While it is unclear where the heaviest rain will fall, some areas may receive more than 50 mm of rain, with localized totals approaching 75–100 mm. 

Depending on where the heaviest bands form, some communities may receive nearly a month's worth of June rainfall.
