A surface low pressure system over northeast New Mexico moved southeast during the late afternoon and evening hours. A cold front moved southeast across the panhandles from northwest to southeast behind the low pressure system. Severe thunderstorms developed across northeast New Mexico during the afternoon and then moved southeast across the panhandles. Low level shear helped to create an environment favorable for tornadic supercells in the Texas Panhandle. Tornadoes were well documented by spotters and storm chasers through photos and video, and four caused minor damage.

Damage from this short track, small tornado included a destroyed grain silo, tree damage, a flipped center pivot irrigation system and minor roof damage to a farm house. This resulted in EF-1 rating with estimated peak winds of 87 mph.

This tornado resulted in flattened grass, a flipped center pivot irrigation system and a small trailer flipped over in a field. This was consistent with EF-0 damage and estimated peak winds of 80 mph.

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 Enhanced Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:58 UTC.

6 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.
