   VALID 100629Z - 100700Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 152
   CONTINUES.
   
   SUMMARY...SEVERE THUNDERSTORM WATCH 152 WILL BE CANCELLED EARLY
   BEFORE EXPIRATION TIME OF 07Z. A FEW STORMS MAY STILL BECOME CAPABLE
   OF PRODUCING ISOLATED HAIL THIS MORNING...MAINLY OVER THE EDWARDS
   PLATEAU...COVERAGE IS EXPECTED TO REMAIN SPARSE. ANOTHER WW IS NOT
   ANTICIPATED UNLESS CONVECTIVE EVOLUTION BEGINS TO SUGGEST A REVERSAL
   OF TRENDS.
   
   DISCUSSION...ISOLATED TO WIDELY SCATTERED STORMS CONTINUE DEVELOPING
   EARLY THIS MORNING FROM THE EDWARDS PLATEAU REGION EWD INTO SCNTRL
   TX. MOST OF THIS ACTIVITY IS OUTSIDE OF WW 152 AND BELOW SEVERE
   THRESHOLDS. THE ATMOSPHERE REMAINS MODERATELY TO STRONGLY UNSTABLE
   WITH RESPECT TO PARCELS ORIGINATING IN THE BOUNDARY LAYER WHICH HAS
   BECOME STRONGLY CAPPED. STORMS CURRENTLY DEVELOPING ARE LIKELY
   ELEVATED AND NOT INGESTING AIR FROM WITHIN THE BOUNDARY
   LAYER...RESULTING IN WEAKER EFFECTIVE BUOYANCY. NEVERTHELESS...STEEP
   LAPSE RATES AND EFFECTIVE SHEAR REMAIN SUFFICIENT FOR A FEW STORMS
   TO ROTATE AND PRODUCE HAIL THROUGH THE EARLY MORNING. HOWEVER...ANY
   SUCH SEVERE EVENTS WILL PROBABLY REMAIN TOO SPARSE TO NECESSITATE
   ANOTHER WW ISSUANCE.
