   AREAS AFFECTED...SOUTH CNTRL THROUGH S TX

   CONCERNING...SEVERE THUNDERSTORM WATCH 104...

   VALID 250355Z - 250500Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 104
   CONTINUES.

   SUMMARY...THREAT FOR LARGE HAIL AND DAMAGING WIND GUSTS MAY PERSIST
   OVER DEEP S TX THROUGH 05Z...BUT THREAT ACROSS REMAINDER OF WW 104
   HAS DIMINISHED AND NO ADDITIONAL SEVERE STORMS ARE EXPECTED.

   DISCUSSION...INCREASING CONVECTIVE INHIBITION HAS RESULTED IN A
   SUBSTANTIAL DECREASE IN SURFACE BASED STORMS OVER ALL EXCEPT FOR
   DEEP S TX WHERE A STRONG/SEVERE STORM IS MOVING INTO SRN HIDALGO
   COUNTY. THIS STORM WILL POSE A THREAT FOR DAMAGING WIND AND LARGE
   HAIL OVER SRN HIDALGO AND POSSIBLY INTO CAMERON COUNTY. THE 00Z
   BROWNSVILLE RAOB SHOWED A SUBSTANTIAL CAP...BUT CONVERGENCE ALONG
   THE CONVECTIVE OUTFLOW BOUNDARY MIGHT BE STRONG AND DEEP ENOUGH TO
   SUSTAIN THE STORM ACROSS THE REMAINDER OF DEEP S TX.
   OTHERWISE...NUMEROUS ELEVATED THUNDERSTORMS ARE DEVELOPING ACROSS
   THE REST OF SOUTH AND SCNTRL TX...BUT THIS ACTIVITY IS LIKELY BASED
   AOA 700 MB AND WILL NOT LIKELY POSE A SIGNIFICANT SEVERE THREAT.
