A significant long-track tornado first touched down 4 miles west of Short, OK, and tracked 39 miles to a point about 7 miles southwest of Fayetteville, AR. Along the way, this tornado passed through portions of four counties but mainly affected sparsely-populated areas. It reached its peak strength as an F3 tornado in extreme southeast Adair County, OK, but mainly caused F2 damage in Washington County, AR. Fortunately, this tornado lifted before it reached heavily-populated Fayetteville. The tornado's first real property damage took place at a property between the Hogeye and Strickland communities, where the tornado peeled off the roof to a home, shattered windows, uprooted trees, destroyed two barns, and wiped a porch off of its stone foundation. Numerous trees were blown down along County Roads 212 and 214. Only a few miles away in the Cove Creek community, south of Prarie Grove, the tornado blew off a home's roof, demolished an enclosed garage, and destroyed a barn. A flagpole was bent almost in half, and a road sign ended up wrapped around a mailbox. The tornado uprooted a 200-year old walnut tree which then fell onto a pickup truck. About a half-dozen other oak and cedar trees on one property dating back at least 150 years were snapped or uprooted. The Washington County Judge's Office supplied a picture of a church near Cove Creek that was moved off of its foundation. Several poultry buildings along the tornado's path were also damaged.The property damage listed in this entry is for just that damage sustained in Washington County, while the F-rating reflects the tornado's peak strength in Adair County, OK.
