   CONCERNING...SEVERE THUNDERSTORM WATCH 524...525...

   VALID 130003Z - 130100Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   524...525...CONTINUES.

   SUMMARY...ISOLATED THREAT FOR DAMAGING WINDS CONTINUES FOR WW
   524/525 AND SURROUNDING LOCATIONS. GENERAL WEAKENING TREND IS
   EXPECTED AS STORMS REACH THE COAST...SUCH THAT WW/S SHOULD BE
   ALLOWED TO EXPIRE AT 02Z AS SCHEDULED.

   DISCUSSION...REGIONAL RADAR IMAGERY AT 00Z SHOWED CLUSTERS OF
   THUNDERSTORMS AND SMALL LINE SEGMENTS OCCURRING FROM SRN NH SWWD
   INTO SERN MD. DESPITE DEWPOINTS NEAR 70F...COOL ONSHORE WINDS AT THE
   SURFACE ARE LIMITING BUOYANCY...WHICH WILL BE FURTHER REDUCED WITH
   THE LOSS OF DAYTIME HEATING. THUS...SEVERE WEATHER THREAT IS
   EXPECTED TO BE ISOLATED IN NATURE AS STORMS TREK TOWARD THE COAST.
   POTENTIAL FOR REDEVELOPMENT OF SEVERE STORMS BEHIND THE LEADING LINE
   OF CONVECTION IS UNLIKELY. THUS...02Z EXPIRATION OF WW 524 AND 525
   APPEARS TO BE ON TRACK.
