EF1 tornado in Osage County, Oklahoma

This tornado developed just east of Highway 11, over the southeastern side of Barnsdall. It damaged homes, destroyed outbuildings, and blew down trees and power poles as it moved east-northeast, dissipating north of County Road 2400 and west of County Road 2335. Based on this damage, maximum estimated wind in the tornado was 90 to 100 mph.

Severe thunderstorms developed along a dry line over central and western Oklahoma during the afternoon of the 1st, as a strong upper level disturbance translated into the Southern Plains. The storms moved through eastern Oklahoma during the late afternoon and evening hours. Moderately strong instability combined with strong deep layer shear to support the development of some supercell thunderstorms, which produced several tornadoes, and damaging wind gusts. The storms evolved into a squall line that also produced damaging wind gusts during the late evening.
