Event narrative (NOAA)
Tornado developed south southeast of Adair and moved quickly north. Initial damage was mainly to trees, grain bins and outbuildings. Three houses were encountered by the tornado with the first two receiving EF0 damage. The third house had the roof removed with several of the outside walls collapsing, but the inside walls remaining intact. Two individuals were sleeping inside when the tornado arrived with one injury and one fatality occurring. This structure sustained EF2 damage with the tornado passing over Interstate 80 and remaining in rural cropland for the remainder of its path in Adair County. The tornado then crossed into Guthrie County before dissipating.
