The episode as NWS CRP wrote it up.
An upper level high pressure ridge remained over South Texas during the first week of August. With humidity combined with afternoon high temperatures ranging from 100 degrees over the coastal counties to around 108 degrees over the Brush Country, the heat index values were near or slightly above 110 degrees for most of South Texas. The excessive heat led to the death of a homeless man in Corpus Christi due to heat stroke and dehydration.
