Yeah I know we have the weather thread, but this one seems a bit more strongly worded? My work just sent out the warning to everyone too.
"Conditions are favourable for the development of severe thunderstorms this afternoon and this evening across portions of Alberta. The main threats will be hail to the size of golf balls, damaging wind gusts in excess of 100 km/h and heavy rainfalls in excess of 50 mm."
