Storm systems hitting Weyburn yesterday and overnight brought significant precipitation and up to toonie sized hail.
Meteorologist for Environment Canada, Stephen Berg, says the Weyburn received five to upwards of 20 millimetres of rain in the past 24 hours. There were also reports of hail, its size and severity varying across the city.
“The way that some of these thunderstorms are coming about, they're very localized in nature. Some of the cells are very small, maybe only a few kilometres across. You'd end up having one area getting toonie-sized hail and another just having rain.”
The hail itself was reported as softer, shattering on impact on the street and sidewalks.
“It depends on the vertical profile of temperature and humidity through the thunderstorm cell itself. If you end up having a little bit more of a warmer profile aloft, the ice might not be quite as hard within a hailstorm. But if you get some cold temperatures in the core of a thunderstorm, those sorts of setups might be more conducive to getting a little bit of a harder hailstorm that might be a little bit rounder with that sort of concentric circle pattern if you cut through it.”
More showers are possible with cooler temperatures predicted for the next few days.
“Friday's high temperature is around 22 for your area. Once that's through, there's a bit of a trough that develops over much of central and western prairies that will bring some cooler conditions. For the week after, it actually looks like it rebounds a little bit and becomes closer to normal, maybe a slight bit above normal for temperatures. It's hard to predict thunderstorms or showers beyond a week or so.”
