The episode as NWS CRP wrote it up.
Low to mid level easterly flow developed over South Texas April 11-12 and began drawing deep moisture into the region. A subtropical jet stream extended across the Pacific and over Mexico leaving South Texas in diffluent wind flow aloft. A complex of thunderstorms developed across southern Jim Wells and western Kleberg counties, along an outflow boundary from earlier convection across the Brush Country and Rio Grande Plains. Between 2-5 inches of rain fell quickly during the morning hours of April 12th, producing flash flooding in near Premont.
