An active round of severe thunderstorms impacted the west Texas South Plains during the late afternoon and evening of the 6th and continued into the early morning of the 7th. ||Convection originated along a dryline near the Texas and New Mexico border, as well as near a pre-existing weak frontal boundary stretched west-to-east over the southwestern South Plains. ||Many of the thunderstorms were supercellular in nature and produced a variety of severe weather hazards, however, splitting and low precipitation modes domininated. While these storm structures helped to limited the overall tornado threat, instances of large hail were widespread. A cluster of low precipitation supercells produced hail up to four and a half inches in diameter over portions of Lamb County. Reports of damage from very large hail also were received in the Lubbock vicinity (Lubbock County). ||A supercell that interacted with the pre-existing surface boundary over the southwestern South Plains did produce a brief and weak tornado that was observed by a research meteorologist. The tornado remained in open country and resulted in no damage.

A research meteorologist documented a short-lived and weak tornado over open country north of Wellman around 17:45 CST. The tornado appeared to have developed as a supercell thunderstorm interacted with a previously existing outflow boundary. Local officials reported no damage in the area.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

The county was under a tornado watch, issued at 20:29 UTC and running to 02:53 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 Slight Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 UTC.

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.
