A strong upper level disturbance moved out of northern Mexico into South Texas from the evening of the 6th into the morning hours of the 7th. Strong to severe thunderstorms developed over the Brush Country during the early morning hours of the 7th. The storms moved into the coastal plains around daybreak on the 7th. Storms produced damaging winds near Beeville and Corpus Christi. A weak tornado damaged trailers near Beeville.

The tornado touched down on Chase Field southeast of Beeville and traveled about a half of a mile across the airport property before dissipating. The tornado damaged around 50 unsecured recreational vehicles (RVs) and severely damaged or destroyed 12 RVs. Several hangars had roof damage with asphalt roofing materials blown off on to the airport tarmac. Several unsecured, full sized single-wide mobile homes were blown over also.

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 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 05:50 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.

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 Corpus Christi radar (KCRP), 67 km away, was scanning. The volume nearest the touchdown began at 12:25 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.
