   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 156
   CONTINUES.
   
   SUMMARY...THUNDERSTORMS ARE INCREASING IN COVERAGE ACROSS WEST
   CENTRAL TX.  THE ENVIRONMENT SUPPORTS A CONTINUED RISK OF LARGE HAIL
   AND DAMAGING WINDS THROUGH THE EVENING.  NEW WATCH MAY BE NEEDED IN
   THE TPL/ACT AREA IF STORMS CONTINUE TO STRENGTHEN.
   
   DISCUSSION...SCATTERED THUNDERSTORMS ARE INCREASING IN INTENSITY AND
   COVERAGE OVER PARTS OF WEST CENTRAL TX.  ONE AREA OF CONVECTION IS
   ALONG/NORTH OF A WEAK SURFACE BOUNDARY EXTENDING FROM JUST NORTH OF
   SAT TO NEAR DRT.  ANOTHER CLUSTER OF STRONG STORMS IS OVER
   COLEMAN/BROWN COUNTIES TX.  THE NORTHERN CLUSTER WILL BE MOVING OUT
   OF WW 156 SOON...AND A NEW WATCH FARTHER EAST IS BEING CONSIDERED. 
   OTHERWISE...STORMS ARE LIKELY TO CONTINUE TO GENERATE OVER THE
   MOUNTAINS OF NORTHERN MEXICO AND DRIFT EASTWARD INTO THE WATCH AREA.
    AMPLE INSTABILITY/LAPSE RATES AND FAVORABLE EFFECTIVE SHEAR WILL
   PROMOTE SUPERCELL STRUCTURES CAPABLE OF LARGE HAIL AND DAMAGING
   WINDS THROUGH THE EVENING.
