Severe storms developed across much of West Central Texas during the evening of the 3rd and continued into the early morning hours of the 4th. A brief tornado was reported near Maryneal in Nolan County, while hail up to the size of grapefruit was reported northwest of Sterling City. Hail up to tennis ball size was reported in Drasco in northern Runnels County, while golf ball size hail fell in Sterling City, Robert Lee, and Lawn.

A slow moving tornado skipped across a 23 mile long path just north of Eldorado in northern Schleicher County. Eleven power poles were snapped, trees uprooted, and at least 2 barns lost their roofs as the tornado passed. Other outbuildings along the path of the tornado were also damaged.

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

33 minutes of warning. NWS SJT issued a tornado warning for this county at 07:22 UTC, 33 minutes before the tornado touched down, in force until 08:40 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 radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The San Angelo radar (KSJT), 48 km away, was scanning. The volume nearest the touchdown began at 07:56 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.
