   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 57
   CONTINUES.
   
   ISOLATED STRONG TO SEVERE STORMS WITH HAIL REMAIN POSSIBLE ACROSS
   VALID PORTIONS OF SVR TSTM WATCH 57. HOWEVER...BULK OF ACTIVITY IN
   THIS WATCH APPEARS TO HAVE WEAKENED OVER THE PAST COUPLE OF HOURS AS
   MORE INTENSE STORMS DEVELOP EAST ALONG SURFACE BOUNDARY.
   
   WITH THE STRONG MID/UPPER LEVEL TROUGH STILL EMERGING ACROSS WEST
   TX...MAGNITUDE OF LARGE SCALE ASCENT WITH THIS FEATURE COULD STILL
   LEND SUPPORT FOR A COUPLE OF MORE INTENSE ELEVATED STORMS INTO THE
   EVENING. LATEST TRENDS...AND LACK OF GREATER DESTABILIZATION...DO
   SUGGEST THAT ANY HAIL THREAT FROM THIS CONVECTION SHOULD REMAIN
   QUITE ISOLATED. IT IS POSSIBLE THAT LARGE PARTS OF SEVERE TSTM WATCH
   57 MAY BE CANCELED PRIOR TO NORMAL EXPIRATION AT 01Z.
