Heavy rain, thunder and marble-sized hail fell in parts of southern Saskatchewan and Manitoba on Tuesday.
"The system moved into the region around mid-day and was largely fueled by daytime heating," says Rob Davis, a meteorologist at The Weather Network.
Callers took to social media and The Weather Network's Stormline to send in reports during the lunch hour Tuesday.
"We're seeing heavy rain and hail in Regina," one caller said. "The clouds are starting to roll in!" Another Weather Network fan reported on Twitter.
Later in the night, Environment Canada issued severe thunderstorm watches and warnings for parts of southern Manitoba. Heavy rain, hail and strong winds were felt across the region.
An additional 10-20 mm of rain is possible along the Saskatchewan, Manitoba border through Thursday.
The warm air that triggered the storms is pushing into southern Ontario, creating a risk for thunderstorms on Wednesday and Thursday.
