This was a multi-day severe weather and flood event. It started with a large-scale upper level low pressure system which deepened over the Four-Corners region. Moisture and instability increased in advance of this system. Storms developed along a dry line Monday afternoon, many of which produced severe weather or flash flooding or both. Another area of storms formed ahead of the upper trough over northwest Texas Monday night and pushed east-southeast across the area Tuesday, producing severe weather and flooding. A third round of storms produced flooding across mainly the southern half of the region Tuesday night into Wednesday.

A National Weather Service storm survey crew found evidence of a tornado which began south of the city of Trinidad, and move northeast to the city of Malakoff. The tornado began by damaging several trees and homes near Trinidad. As the tornado moved northeast, trees were damaged along State Highway 34, before entering southwest Malakoff. Approximately 10 homes were damaged in Malakoff, with one home losing a chimney, part of the roof, and several large trees on the property.

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:35 UTC.

10 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.
