Tennis ball sized hail pummelled the Barrier Lake Region on Saturday as a powerful set of storm cells worked their way across east central Saskatchewan. The storms lingered over pockets of the Humboldt region, dumping the largest single event precipitation amounts of the summer. 

The storm also came with high winds that led to downed trees and power lines and toppled grain bins in the Wadena area. Barrier Lake took the brunt of the damage with tennis ball sized hail reported causing considerable property and vehicle damage. In Vonda, there was a report of an uprooted tree that fell onto and damaged a car. 

Quarter-sized hail was reported in Nokomis, Kipabiskau and Melfort. Locally amounts of precipitation registered 80 mm - 125 mm or more in isolated spots. 

The wild weather continued on Sunday, this time in the southeast corner of the province, says Natalie Hassel, warning preparedness meteorologist with Environment and Climate Change Canada. 

“We saw another set of storms go through mainly in the southeastern corner. They kind of came in three waves. At 6:10 pm, we had golf ball sized hail reported southeast of Weyburn and tennis ball sized hail reported at 6:30 pm just east of Weyburn, and at 7:10 pm near Fillmore.”

The next wave struck Regina knocking power out at around 12:30 am. Loonie sized hail was reported in southeast Regina about 15 minutes later, and close to 12:50 am, golf ball sized hail in eastern Regina.

The third and final wave rolled through at about 3:00 am and dropped loonie sized hail on Churchbridge and area. 

High humidity and plenty of upper air energy led to the weekend mayhem. The forecast looks for calmer conditions, but daytime heating always has the potential to generate thunder cells.
