An active round of severe thunderstorms, including damaging tornadoes, affected a large portion of the Southern Plains of the U.S. during the afternoon and evening hours of the 23rd. Supercell thunderstorms with a history of producing deadly tornadoes propagated northeastward from the plains of eastern New Mexico into the extreme southwestern Texas Panhandle and the western South Plains of west Texas during the evening hours. As these storms moved eastward across the state line, convective modes transitioned from classic supercells toward mini-bow segments and line-echo-waves. Despite the linear nature of the storms, extreme wind shear resulted in at least five tornadoes across the western South Plains region.
Tornadoes were initially observed in the extreme southwestern Texas Panhandle and the northwestern South Plains around 20:00 CST. The hardest hit area was the Bovina vicinity in Parmer County, where a weak tornado struck the city resulting in minor structural damage.
Severe storms producing widespread wind damage and at least one strong tornado then impacted portions of Cochran, southern Bailey, and Lamb Counties during the late evening hours. Two cotton gins in Cochran County were severely damaged, and power outages were widespread.
No injuries were reported during the severe weather outbreak on the 23rd, but property damage estimates totaled more than $400,000.
