Across southeast Saskatchewan, people were looking to the skies as pop-up thunderstorms crossed over the region. Areas saw as little rain as just 1.5 millimetres while others, just a few kilometres over, saw as much as 35 millimetres.
Terri Laing is a warning preparedness meteorologist with Environment Canada. She explained the unsettled weather experienced on the weekend was due to pop-up thundershowers, which can be very unpredictable in both scope, and location.
“They’re driven by the sun itself,” Laing said. “The airmass is really unstable, it’s really humid, so as soon as the sun gets working on them we get these thundershowers popping up, but they’re almost impossible to know where they’re going to pop up, and then where they’re going to move.”
As the storm collapses, the cooler air outflows from the storm, according to Laing, This can cause other storms to pop up.
The systems which have been passing through tend to bring with them rain, thunder and lightning, with the occasional funnel cloud, including the landspout tornado seen by Griffin on Saturday.
As for what the rest of the week will bring, Laing said a cold front will be passing through the southeast over the next few days, bringing temperatures closer to normal for this time of year. There could be more unsettled weather, including the chance of more rain as the week goes on.
