   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 50
   CONTINUES.
   
   SUMMARY...A SVR WEATHER THREAT IS EXPECTED TO PERSIST FOR THE NEXT
   1-2 HOURS /THROUGH 09Z/ ACROSS MAINLY SOUTH CENTRAL TX /SERN PORTION
   OF WW 50/.  GIVEN THIS POTENTIAL...LOCAL WFO TEMPORAL AND SPATIAL
   EXTENSIONS MAY BE NEEDED. STRONGEST STORM OR TWO WILL TEND TO POSE A
   THREAT FOR HAIL APPROACHING 1 INCH IN DIAMETER AND/OR A BRIEF STRONG
   WIND GUST.
   
   DISCUSSION...AT 0720Z...REGIONAL RADAR AND SATELLITE IMAGERY
   INDICATED THE STRONGEST STORM CLUSTER WAS LOCATED OVER BEXAR...COMAL
   AND FAR WRN GUADALUPE COUNTIES TX...WHILE STORMS ACROSS THE REST OF
   WW 50 TO THE NE AND SW OF THIS CLUSTER HAS GENERALLY WEAKENED.  SREF
   AND HIGH RESOLUTION MODELS SUGGEST THE ONGOING STORMS WILL CONTINUE
   TO GRADUALLY DIMINISH IN INTENSITY AS THE INSTABILITY WEAKENS.  THIS
   TREND APPEARS TO BE UNDERWAY GIVEN THE OVERALL DECREASING TREND IN
   STORM INTENSITIES.  RECENT STORM REPORTS FROM BEXAR COUNTY INDICATED
   SUB-SVR HAIL AND A SUB-SVR WIND GUST AT KSAT /38 KT AT 0706Z/. 
   THESE REPORTS SUGGEST SURFACE BASED INHIBITION HAS BECOME
   SUFFICIENTLY STRONG TO LIMIT THE OVERALL SEVERE WEATHER THREAT.
