A strong upper level trough generated scattered to numerous thunderstorms across North and Central Texas on Saturday April 13. Storms were mainly hail producers early in the day, but damaging winds and a few tornadoes occurred across the southern counties in the vicinity of a stationary front in the late morning and afternoon hours.

A brief EF-0 tornado was confirmed from 3 videos just east of the town of Mumford, TX in southern Robertson County. No damage was reported as the track stayed in open farmland.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a severe thunderstorm watch, issued at 13:46 UTC and running to 18:16 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 16:12 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

35 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.
