Thunderstorms with big hail and tornado risk in Alberta on Friday
Some areas of Alberta could be under the threat of severe thunderstorms Friday, with certain spots even seeing the risk of huge hail and a tornado.
According to Environment and Climate Change Canada (ECCC), thunderstorm outlooks from the Storm Prediction Centre say that there is an area of moderate risk Friday for large hail and the chance of a tornado forming.
It’ll be the second consecutive day of severe weather with a tornado risk, with today, July 24, landing under a high risk.
Forecasters noted that tomorrow, Friday, July 25, is shaping up to be a concerning day for severe weather over southern Alberta, according to the outlook, with ECCC taking note of a cold front pressing southwards in the province.
“Warm humid air will provide plenty of instability, the 500 mb jet will be well positioned in the region, and some guidance suggests an easterly flow near the foothills, which would add to bulk wind shear.”
The moderate risk in Alberta for Friday encompasses a large stretch of southern Alberta, with cities like Calgary, Lethbridge, and Medicine Hat under the gun for the threat of wind gusts up to 100 km/h, hail up to five centimetres in size, rainfall up to 50 millimetres, and the chance of a tornado popping up.
A minor risk zone is also present in southern and portions of northern Alberta, with areas like Grande Prairie, Fort McMurray, High Level, and Lloydminster potentially seeing thunderstorms with wind gusts of up to 70 km/h, hail up to two centimetres in size, and 30 millimetres of rain. A risk of funnel clouds forming across northern sections of the province is also in play.

Taking a look at the seven-day forecast for Edmonton and Calgary, both cities are set to see plenty of showers, especially in YYC. It sure has been a rain-rich July! Fingers crossed it stays dry for the upcoming August long weekend, and from the looks of the middle of next week, the heat may be arriving.
