EF0 tornado in Okfuskee County, Oklahoma

Storm chaser video and a debris signature from KINX WSR-88D indicated this tornado began west of Highway 48, about 6 miles north-northwest of Castle. The tornado crossed Highway 48, where it damaged the roof of two mobile homes and snapped tree limbs along the E980 Road before dissipating. Based on this damage, maximum estimated wind in the tornado was 70 to 75 mph.

Severe thunderstorms developed into eastern Oklahoma during the late afternoon of the 6th, ahead of a surface dry line, and moved across the area through the evening hours. The atmosphere had become strongly unstable across eastern Oklahoma during the afternoon east of the dry line. This instability, combined with very strong low-level and deep-layer wind shear across the region, resulted in the evolution of several long-lived supercell thunderstorms. These supercells produced eleven tornadoes, a couple of which were strong and damaging, large hail up to quarter size, damaging wind gusts, and localized flash flooding.
