EF1 tornado in Jefferson County, Oklahoma

This tornado moved east-southeast out of Stephens County into Jefferson County. The tornado then turned southeast and dissipated soon after crossing State Highway 89 between E1890 Road and E1900 Road. In Jefferson County, at least four homes were damaged and a couple of barns were damaged or destroyed as well as many trees damaged.

The approach of an anomalously strong (for mid-June) upper-level disturbance lead to a widespread severe weather outbreak across portions of the forecast area, especially along and west of the I-35 corridor, during the afternoon into late evening of the 15th. This included the development of numerous supercell thunderstorms across the area. Despite relatively high cloud bases, strong low-level instability and sufficient low-level wind shear aided tornadic outcomes, with eleven tornadoes confirmed across western into southern Oklahoma. Numerous reports of large to very large hail, including reports of 4-inch hail in Lawton, and wind damage were received across area.
