Severe thunderstorms produced large hail and tornadoes across the eastern Texas Panhandle during the evening and early morning hours. One tornado did cause extensive damage in Gray County and another tornado which traveled from northeastern Collingsworth County into southeastern Wheeler County caused damage to a stand of trees. Another tornado in Collingsworth County caused no damage. No injuries were reported from the storms.

The tornado remained over open country and the path length and path width were estimated. No damage or injuries were reported.

This tornado developed fourteen miles northeast of Lutie in northeastern Collingsworth County and tracked north northeast for about a half a mile before exiting Collingsworth County about fourteen and a half miles northeast of Lutie at 1828 CST. The tornado continued north northeast into Wheeler County before finally dissipating nine miles east northeast of Shamrock at 1836 CST. The tornado caused no damage in Collingsworth County.

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.
