EF1 tornado in Osage County, Oklahoma

This tornado developed near the intersection of County Road 5408 and County Road 5257, and moved east-northeast. It crossed Highway 99, moved northeast, and dissipated after crossing County Road 2701. Numerous trees were uprooted or snapped, most heavily west of Highway 99, and numerous power poles were blown down. Based on this damage, maximum estimated wind in the tornado was 100 to 110 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.
