   CONCERNING...SEVERE THUNDERSTORM WATCH 365...
   
   VALID 250810Z - 250945Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 365
   CONTINUES.
   
   SEVERE TSTM WATCH 365 CONTINUES UNTIL 09Z...A LOCAL WFO EXTENSION
   AND/OR A REPLACEMENT WATCH WILL NEED TO BE CONSIDERED. SEVERE HAIL
   WILL REMAIN POSSIBLE ON AN ISOLATED BASIS OVERNIGHT MAINLY ACROSS
   PORTIONS OF CENTRAL TX.
   
   A SUPERCELL/ISOLATED SEVERE TSTMS CONTINUE TO STEADILY PROGRESS
   EASTWARD IN THE GENERAL VICINITY OF I-35 NORTH OF AUSTIN AS OF 08Z.
   PER REGIONAL PROFILERS/WSR-88D VWPS...THIS ACTIVITY APPEARS TO
   GENERALLY BE FOCUSED WITHIN A ZONE OF CONFLUENCE JUST ABOVE THE
   SURFACE. AS PER MODERATELY STRONG SOUTHWESTERLY WINDS AROUND 1 KM
   AND THE 00Z OBSERVED DEL RIO RAOB...A VERY MOIST/UNSTABLE
   SOUTHWESTERLY INFLOW JUST ABOVE THE SURFACE WILL MAINTAIN A SEVERE
   HAIL THREAT AT LEAST ON AN ISOLATED BASIS IN THE SHORT TERM. WHILE
   CURRENT THINKING IS THAT THE SEVERE THREAT WILL EVENTUALLY
   WANE...AREAS OF WW 365 ARE BEING MONITORED FOR THE POSSIBILITY OF AN
   ADDITIONAL WATCH AND/OR A WFO EXTENSION BEYOND 09Z.
