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.

The Levelland Fire Department reported a second tornado west-northwest of Morton shortly before 22:30 CST. A National Weather Service damage survey found evidence of a strong tornado that developed west of Morton and crossed Texas Highway 114 as it tracked north-northwestward through north-central Cochran county. The tornado impacted the Star Route Gin, which sustained severe damage including the partial collapse of the structure. Concrete anchors were pulled out of the ground and portions of the steel roof beams were heavily damaged.|The tornado continued north-northwestward across Farm to Market Road 596 where the tornado destroyed at least three irrigation systems and snapped more than one dozen utility poles. |Damage at the Star Route Gin and the snapped utility poles support an EF-2 rating. No injuries were reported and damage estimates totaled $175,000.

12 minutes of warning. NWS LUB issued a tornado warning for this county at 04:10 UTC, 12 minutes before the tornado touched down, in force until 04:45 UTC.

The county was under a tornado watch, issued at 02:57 UTC and running to 08:57 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Moderate Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 00:53 UTC.

17 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
