Northwood, ND EF4 Tornado of August 26, 2007

 A devastating tornado struck the city of Northwood, ND at 0145 UTC (845 pm CDT) on the evening of August 26, 2007. One person perished and 18 others were injured, with nearly 60 million dollars in damage.  The tornado was nearly 1 mile wide with damage done to nearly every structure in the city.  The north side of the city sustained the most significant damage, where a powerful suction vortice likely developed within the larger tornadic circulation.  The tornado occurred very close (18 miles) to the KMVX 88 Doppler Radar, so high resolution radar data continues to be studied.
