The combination of a strong upper level area of low pressure and a surface dryline resulted in a few rounds of severe thunderstorms across portions of west central Texas. In addition, strong to extreme instability and strong vertical wind shear assisted with severe thunderstorm development. The severe storms produced large hail and a tornado in Shackelford County on May 18th.

A severe thunderstorm moved across western portions of Callahan |County late Sunday afternoon which produced a brief tornado about|6 miles south to southwest of Clyde, Texas near FM 604. Clyde VFD|sent a video of the tornado touching down west of Lake Clyde. |Time and exact location estimated from radar. No significant |damage was reported with this tornado as of today. Therefore...the|tornado has been classified as EFU, which means the winds |associated with the tornado are unknown at this time.

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 20:05 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.
