Edmonton hit a high of 28 C on Canada Day and should be two or three degrees hotter today.

We’ll be sunny with a few clouds this afternoon and up around 30 C for a high.

But, as the upper ridge collapses off to the east, we’ll see some thunderstorms develop in western Alberta late this afternoon with the potential for severe thunderstorms.

The highest risk for severe storms is in areas west and northwest of Edmonton in the 5-9 p.m. window. However, almost all of the province faces at least a moderate risk of severe storms.

Keep an eye on the severe weather advisories later today as the situation develops.

As always, most areas will not get hit with a severe storm.

But...areas that do get hit could see large hail and damaging wind gusts (near or over 100 km/h). There’s also a slight tornado risk, especially in areas from Edson northeast towards Whitecourt and Slave Lake.

For the Edmonton region, there is a minimal risk of thunderstorms late this afternoon and a better chance this evening/late tonight.

Sunny and highs near 20 C for Thursday/Friday in the city.

We’ll get another shower/thunderstorm risk late Saturday.

Temperatures start to ramp up again early next week and it looks like we could be in for a lengthier stretch of highs in the 26-30 C range next week.
