   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 314
   CONTINUES.
   
   SCATTERED CONVECTION HAS BECOME A BIT MORE ORGANIZED ALONG/AHEAD OF
   FRONTAL BOUNDARY AS IT SURGES EAST OF THE HIGHER TERRAIN ACROSS SERN
   PA INTO WRN VA.  AIRMASS IS NOT THAT UNSTABLE ACROSS ERN PA/NJ...BUT
   REMAINS QUITE BUOYANT FARTHER SOUTH OVER SRN MD/VA WHERE MLCAPE IS
   HOLDING AOA 2000 J/KG.  IT/S NOT ENTIRELY CLEAR HOW NRN UPDRAFTS
   WILL INTERACT WITH COOLER MARITIME AIRMASS OVER NJ AND PORTIONS OF
   DE...BUT ACTIVITY SHOULD CERTAINLY MAINTAIN ITS INTENSITY WHERE
   STRONGER INSTABILITY REMAINS...PRIMARILY OVER VA/SRN MD.
