First Widespread Severe Weather Event of 2009

Residents of eastern North Dakota and western Minnesota experienced the first widespread severe weather of the 2009 severe weather season Thursday afternoon and evening. A very moist and unstable airmass moved in earlier in the week, resulting in significant flooding across the southern basin Tuesday night into Wednesday. A potent upper level wave of energy moving out of the southwest US interacted with this moisture, setting of a large area of storms, quite a few of which were severe. One particular group of storms moving out of south central North Dakota produced significant wind damage and a few tornadoes, with the greatest damage along a line from around Wyndmere and Wahpeton North Dakota towards the Fergus Falls area in Minnesota.

Below is a list of severe weather reports through 800am Friday morning, June 20th. An NWS meteorologist is enroute to perform a storm damage survey, and will likely have more information later in the day.
