A National Weather Service storm survey team joined Douglas County Emergency Management in the field the afternoon of May 13th to assess wind damage in southern Douglas County. A farm sustained damage to several sheds, a concrete silo, several wooden structures on the property, and a number of trees. Tin from the sheds was blown around one quarter of a mile downstream. The survey team determined the damage had been caused around 11pm by 75-80 mph straight line winds due to the unidirectional damage path.
