Thunderstorm Wind in Love County, Oklahoma

A swath of intense damaging winds, associated with a quasi-linear convective system (QLCS) mesovortex, impacted areas from southwest to just north of Marietta. Numerous power poles and trees were damaged along Shady Dale and McGehee Roads southwest of town. Several tractor-trailers were blown over along Interstate 35. The most significant damage occurred near the corner of West Creek Street and South 7th Avenue, where a home lost a significant portion of its roof, causing two exterior walls to collapse. Several businesses near Oklahoma Highway 32 and U.S. Highway 77 had varying degrees of roof damage. Intermittent damage to trees and power poles was also noted in Marietta. The wind path and event time are estimated.

As a closed upper low across the Baja Peninsula transitioned to an open wave and moved to the northeast, widespread convection developed from western-north Texas into much of Oklahoma during the evening of the 10th. Strong surface heating in the afternoon contributed to strong instability and, combined with increasing deep-layer wind shear, yielded an environment capable of organized thunderstorms. The most impactful storm of the event was a supercell thunderstorm that develop across west-central Oklahoma and tracked across the greater Oklahoma City metropolitan area, producing large to very large hail and a weak tornado. By mid-evening, a developing quasi-linear convective system (QLCS) produced sporadic (yet intense) thunderstorm wind damage across portions of far southern Oklahoma.
