Ripe for a few severe storms

Update: 1:40 pm. Doppler Radar shows a line of intense thunderstorms developing rapidly well north and west of the Twin Cities metro. There is evidence of 3/4" diameter hail in some of these storms near Wadena and Alexandria. If hail reaches 1" in diameter (roughly quarter-size) warnings will be issued for specific counties acrdoss Minnesota, which is increasingly likely between 3 and 6 pm. Most of us will just see a heavy thunderstorm and gusty winds; a tiny percentage of the region may experience large, damaging, (ping pong-size) hail, wind gusts over 70 mph, even an isolated tornado can't be ruled out in this moist, unstable, highly sheared environment. Stay alert and be ready to move to a safe place if warnings are issued for your county.
