Golf ball sized hail, potential tornado threat across Alberta today


After a week of severe weather in Alberta last week, the threat returns today with the potential for hail and golf ball sized tornadoes.

The main areas of concern will be near Calgary and north along QE2 towards Red Deer until late afternoon. The storms that do develop will track eastward in the evening, progressing towards the provincial border.

“Strong to locally damaging gusts of wind would be the main threat, along with large hail that could reach the size of a golf ball in some of the strongest storms,” ​​said Kelly Sonnenburg, meteorologist at The Weather Network.

“Supercells and rotating storms are also possible and most likely in areas east of Red Deer and Calgary. If the storms start to turn, we will have to keep an eye out for the tornado threat,” she added.

Last week, four tornadoes touched down in Alberta, with a severe storm spawning three tornadoes in central Alberta on Tuesday and a tornado damaging several homes in an area northwest of Calgary on Thursday.

Environment Canada issued several heat warnings earlier this week, including for the city of Calgary, Okotoks, Drumheller, Lloydminster and Cold Lake.

“Temperatures reaching 30 degrees Celsius combined with overnight lows near 15 degrees continue,” the federal weather agency said.

“Temperatures are expected to cool down this evening with the passage of a cold front before warming up again on Thursday and continuing through the weekend.”

Heat warnings are issued when very high temperature conditions are likely to pose a high risk of heat-related illnesses, such as heat stroke or heat exhaustion.
