A mid level circulation from the Duval County storms drifted northward into McMullen county late on the evening of the 15th, and through the morning hours of the 16th, redeveloping strong showers and thunderstorms.  This circulation embedded in the mean upper level trough axis which had shifted over central South Texas fed on a moist and unstable air mass (1.6 inches precipitable water and 2000 J/KG surface-based CAPE) supplied by the persist low level easterly flow.  A complex of thunderstorms centered over Choke Canyon produce torrential rains overnight and significant flash flooding from Tilden to Three Rivers to Oakville.  Radar estimated as much as 12 inches of rain fell on the west side of Choke Canyon Reservoir and an observer in Cross reported 7 inches.  Flooding was extensive to the areas around the Reservoir and the water level rose 2.5 feet by midday Friday.
The thunderstorms shifted east of I-37 Friday morning and brought very heavy rain into Bee County.  The rich moist air mass remained in placed and the upper level trough extension shifted into the Coastal Plains by Friday afternoon.  This resulted in a weaker sea breeze and a focus of low level convergence along highway 281 and eastward.  Local areas of intense thunderstorms developed Friday afternoon from Orange Grove to Sinton and northeast to the Victoria Crossroads region.  This area of thunderstorms was very slow moving and produced embedded mid level circulations within the weak but diffluent wind flow aloft.  Torrential rainfall totals of 4 to 8 inches occurred leading to widespread areal and flash flooding in Orange Grove and Agua Dulce and localized flooding into the northern Coastal Bend.  Rainfall was so intense that runoff closed many roads, flooded numerous homes, surrounded some homes with a foot or slightly more of standing water, and turned normally dry creeks and drainage canals into ragging torrents.  At least one water rescue was performed when a vehicle was swept into deep water.  The precipitation diminished quickly Friday evening as it moved into the Coastal Bend and the associated upper level trough extension shifted over the West Gulf.
