The tornado began just south of Highway 34 along the Red Willow and Hitchcock County line. The tornado moved north-northeast across Red Willow County before ending northwest of McCook, NE. The tornado struck a farm and this is where the most intense damage was done. Otherwise, damage consisted of sporadic tree  limbs down, some barbed wire fences knocked over, irrigation pivots overturned, and minor loss of metal roofing.
The primary damage occurred when the tornado moved across a farm. The tornado entered the property from the southwest, where it went through a wind break and snapped numerous hardwood and softwood trees. The storm also destroyed 6 grain bins, 5 farm outbuildings, and produced significant damage to a house. The EF-2 rating is a direct result of the house damage, which consisted of a few collapsed exterior brick walls, uplift or removal of half of the structure's roof, and complete removal of the garage. Additional damage included shattered windows to the house and vehicles, damage to a combine due to being struck by a grain bin, damage to fences, and other trees with losses to branches.
