EF1 tornado in Cleveland County, Oklahoma

The low-end EF1 tornado developed at the southern edge of the Summit Lakes addition just southeast of 24th Avenue SE and Alameda Street, then moved through the Highland Hills addition just northwest of 48th Avenue SE and Lindsey Street. Numerous trees were damaged and a small number of homes received minor roof damage. Monetary damage estimates were not available.

On the evening of June 12th, an outflow boundary extended from Norman to Holdenville, with a dry line south of the Red River over western north Texas. A strong cap suppressed thunderstorm development through much of the day, but finally weakened enough by late afternoon and early evening for thunderstorms to develop. Thunderstorms crossed into south central Oklahoma, producing hail up to half-dollar size through mid evening before weakening. Thunderstorms also formed along the outflow boundary across central Oklahoma and rapidly became severe, producing an EF1 tornado in Norman.
