EF2 tornado in Swisher County, Texas

A large and long-tracked tornado cut a path of damage twenty-nine miles in length and at times nearly three-quarters of a mile wide across portions of Lamb, Hale, Castro and Swisher Counties between 17:57 and 18:36 CST on the 21st. Total damages from the tornado were estimated to exceed $1.2 million, and one person was injured.

The tornado was in the final stages of its life cycle as it crossed into extreme southwestern Swisher County at 18:33 CST. Storm chasers documented an extended rope-out phase before the tornado finally dissipated over cotton fields in southwestern Swisher County at 18:36 CST.

Reports in local newspapers indicated that at least one center pivot irrigation system was heavily damaged west of Kress.

Damage caused by the tornado east of Olton (Lamb County) supported an EF-2 rating with winds estimated between 110 and 120 mph.

An outbreak of severe weather impacted much of the central U.S. from Minnesota to Texas during the late afternoon and evening hours of the 21st. The west Texas South Plains and the extreme southern Texas Panhandle were affected by a series of significant tornadoes. At least five tornadoes were spawned by a single cyclic supercell thunderstorm that resulted in more than $3.5 million in damages.

The most severely impacted communities included Olton (Lamb County) and Tulia (Swisher County). Both of these west Texas towns were impacted by EF-2 tornadoes that destroyed property and injured four people, and more than 14,000 customers were without electrical power throughout the night.

The tornado outbreak was caused by a potent storm system that progressed east over the Four Corners region of the western U.S. on the 21st. A potent upper level jet stream spread over the Southern Plains of the U.S., and helped to create a favorable environment for supercell thunderstorms and tornadoes along a dryline that was stretched across west Texas.
