The combination of deep tropical moisture and a weak stalled frontal boundary led to scattered showers and thunderstorms across the southern Texas Panhandle initially, with activity spreading north through the afternoon and evening. There was moderate instability, but extremely weak wind shear present in the atmosphere and storms were disorganized, pulsy in nature. The strongest storms occurred where outflow boundaries collided in the late afternoon and evening. One strong boundary collision just east of Dumas, Texas led to an unusually strong and long-lived landspout that developed on the northern edge of a thunderstorm, which was generated by the boundary collision. The landspout moved nearly due north and was on the ground for around 6 minutes and just shy of 2 miles.

The landspout tornado damaged some out buildings and ripped half the roof off an older mobile home which was one of the main damage indicators for this event. Several empty semi tractor trailers at a trucking company were flipped and pushed several yards. Toward the end of the damage path, the tornado destroyed a poorly constructed and old cabin/storage building. Power lines along the path were not damaged and a mobile home directly adjacent to the poorly constructed destroyed building only showed very minor damage. These factors suggest a high end EF0 rating with maximum winds around 85 mph. This survey utilized pictures and information provided by Moore County Emergency management. The landspout was well documented on video by numerous witnesses.

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

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 General Thunderstorms Risk. The outlook in force was issued at 19:45 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.
