EF3 tornado in Okmulgee County, Oklahoma

This tornado began on the west side of Beggs, directly impacting the Beggs Public Schools campus. The High School and Middle School roof sustained significant damage, and the bus barn also suffered heavy damage to the roof and overhead doors. As it moved northeast, it crossed 15th Street, uprooting and snapping trees. After crossing Happy Camp Road, it destroyed outbuildings and began a brief jog northward, paralleling North 180 Road. This strongest and widest phase of the tornado occurred as it moved east along Grimes Road. One single-wide manufactured home was completely destroyed and several other single-family residences were heavily damaged with the loss of roofs and windows. Two fatalities and two injuries occurred at one homestead, where a double-wide manufactured home was completely destroyed and several automobiles were moved and tossed 20 to 30 yards. A nearby barn was destroyed and heavy limb loss occurred on large trees. The tornado then continued northeast, crossing Highway 75, where it threw a metal shipping container across the lanes and uprooted trees. The tornado dissipated after crossing North 205 Road, about three miles south of the Tulsa County line. Based on this damage, maximum estimated wind in the tornado was 135 to 145 mph. The tornado produced a tornadic debris signature from the KINX WSR-88D.

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.
