EF2 tornado in Lamb 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 development of this significant tornado was witnessed by storm chasers between Fieldton and Otlon at 17:57 CST. A National Weather Service damage survey team noted that the first damages to occur as a result of the tornado included five medium voltage power poles downed just east of the intersection of Farm to Market Road 168 and County Road 162. Just east of this location, the tops of five power poles were blown off to the north and two center pivot irrigation systems were overturned. One irrigation system was blown toward the west and another toward the northeast.

Farther to the northeast along the tornado's path, along County Road 152 just east of Farm to Market Road 168, two power poles were sheared off above the ground. At this location, a historic multi-story house that was originally constructed in 1913 suffered severe roof damage. A portion of the roof was blown off of the structure toward the southeast. The owners of the home were within days of completing a two year-long renovation. In addition, the skirting was removed from a mobile home across the street from the historic home. Several outbuildings near the residence also sustained minor damage.

The tornado continued northeastward and destroyed several more center pivot irrigation systems and snapped utility poles three to five feet above the ground along County Road 321. The tornado's damage path was measured at seven-tenths of a mile wide in this area.

As the tornadic circulation crossed U.S. Highway 70 two miles east of Olton, four homes were heavily damaged. Two well-built brick structures suffered total roof losses. The resident of one home, and elderly woman, suffered minor injuries while seeking shelter under a kitchen table. A number of light-weight medal structures were destroyed, along with three vehicles and several pieces of farm equipment. One family pet, a dog, was killed at one of the residences.

The tornado killed an unknown number of live-stock as it continued northeast of U.S. Highway 70. The damaging tornado crossed the Lamb and Hale County line at 18:10 CST.

The damages sustained by two of the well-built single-family residences, light-weight medal structures, and numerous utility poles support an EF-2 rating. Winds were 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.
