Meteorologist Paul Douglas writes about Minnesota weather daily, trying to go beyond the "highs" and "lows" of the weather story to discuss current trends and some of the how's and why's of meteorology. Rarely is our weather dull - every day is a new forecast challenge. Why is the weather doing what it's doing? Is climate change a real concern, and if so, how will my family be affected? Climate is flavoring all weather now, and I'll include links to timely stories that resonate with me.

Severe T-Storm Risk
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.
