A shortwave that turned into a baggy trough over eastern Texas provided Deep South Texas and the Rio Grande Valley with several rounds of showers and storms June 3rd through June 5th. Large hail fell in a storm just northwest of Rio Grande City on June 3rd before turning into a sub-severe line of showers and storms across the populated Rio Grande Valley.
Northwesterly flow aloft on the southwestern side of the trough led to several more showers and storms across the eastern half of Deep South Texas and the Rio Grande Valley on June 4th. The storms headed south from Corpus Christi's area and moved along the coast of Kenedy and Willacy Counties before moving southwestward into Cameron County where it produced very large hail, up to 2.5 in diameter, and 80 mph wind gusts at Valley International Airport in Harlingen. Additional storms flared up in Hidalgo County and produced 1 hail.
The storms on June 5th followed a similar script to June 4th with storms along the coast of Kenedy and Willacy Counties before developing inland. While the storms weren't as strong, they still produced large hail in northern Cameron County and 50 to 60 mph wind gusts near Brownsville.
