Thunderstorm Wind in Seminole County, Oklahoma

Wind gust near the intersection of Interstate 40 and U.S. Highway 377.

A high-amplitude (closed) upper storm system moved eastward across the Rockies on the 3rd and fostered a severe convective episode across portions of Oklahoma and western-north Texas. Initial thunderstorm development during the afternoon focused along a cold front from southwest into north-central Oklahoma, with a mix of multicell and supercell storm modes producing hail. Later in the evening, an intense complex of thunderstorms moved from west-central into east-central Oklahoma, including across the Oklahoma City Metropolitan area. This cluster produced swaths of damaging winds and several tornadoes. By the late evening, increasing frontal thunderstorms moved towards the Red River, producing intermittent wind gusts/damage and flooding.
