Okotoks, Calgary and areas to the south were hit by a severe thunderstorm Tuesday afternoon just before 5 o'clock.

Facebook photos show Highway 7, between Okotoks and Aldersyde covered in hail making it look more like winter than summer.

High winds accompanied the hail which only fell for a short time in High River.

No reports of serious damage, other than to flowers and gardens.

One casualty however is the Highwood High School Graduation.

The ceremony itself will still go ahead as planned Thursday at George Lane Park, but the grad dinner and dance featuring guest speaker Chris Koch has been moved from the High River Agricultural Grounds, to the "Yellow Field" at the Crescent Point Energy Fieldhouse in Aldersyde.
