   MID LEVEL WINDS ARE GRADUALLY VEERING ACROSS SOUTH TX AS A WEAK
   SHORTWAVE TROUGH DIGS SEWD TOWARD THE NWRN GULF OF MEXICO.  THIS
   FEATURE APPEARS PARTLY RESPONSIBLE FOR MAINTENANCE OF ONGOING MCS AS
   IT TRACKS STEADILY SEWD AT ROUGHLY 30KT.  WHILE THE LEADING EDGE OF
   STRONGEST STORMS NOW STRETCHES ALONG THE BRO/CRP CWA
   BORDER...ADDITIONAL THUNDERSTORMS ARE DEVELOPING ALONG AN E-W WIND
   SHIFT ACROSS THE NWRN GULF INTO THE DIGGING MCS.  GIVEN THESE
   TRENDS...STRONG THUNDERSTORMS SHOULD OVERSPREAD THE REMAINDER OF
   DEEP SOUTH TX BY MID MORNING WITH AT LEAST A THREAT FOR ISOLATED
   LARGE HAIL AND VERY HEAVY RAIN.
