The combination of upper level energy diving southeast from the central Plains into the northwestern Gulf region with a dissipating front moving toward Deep South Texas triggered strong to severe thunderstorms across Brooks County, which quickly raced southward into Hidalgo and Starr County. These storms produced a combination of strong, locally damaging winds, hail, frequent lightning, and brief torrential rains during the early to mid evening hours. Funnel clouds and one tornado were noted.||One storm, a mini-supercell, showed significant rotation while moving into rural southwestern Brooks County. This storm evolved into a bow shaped event as it reached the populated portion of Hidalgo County from west of Edinburg through Mission. While it was possible that minor damage reported near Alton (north of McAllen) may have been from a small tornado touchdown, there were no visual confirmations at the time.

The Starr County Emergency Manager reported seeing a funnel cloud touchdown briefly near the intersection of 755 and 490 just east of 755 and approximately 1/4 mile north of 490 near the city of Rincon. The Emergency Manager estimated the tornado was approximately 100 feet wide and touched down in the open on ranch land. No damages occurred during this event.

31 minutes of warning. NWS BRO issued a tornado warning for this county at 23:59 UTC, 31 minutes before the tornado touched down, in force until 00:30 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 General Thunderstorms Risk. The outlook in force was issued at 19:26 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.
