   THE SEVERE WEATHER THREAT FOR TORNADO WATCH
   100...98...99...CONTINUES.
   
   LARGE SCALE FORCING APPEARS TO BE INTERACTING WITH WRN EDGE OF BROAD
   PRE-FRONTAL CONVECTION PER INCREASING THUNDERSTORMS FROM NEAR LYH
   VA...SSWWD TO NEAR FLO SC.  SHEAR PROFILES ARE QUITE STRONG...AND
   WILL ONLY INCREASE OVER THE NEXT FEW HOURS AS LLJ STRENGTHENS EAST
   OF THE APPALACHIANS.  BOUNDARY LAYER MOISTURE HAS ALSO INCREASED
   ACROSS THE MIDDLE ATLANTIC WITH SFC DEW POINTS NOW INTO THE
   LOWER-MID 60S.  ALTHOUGH THE DOMINANT STORM MODE SHOULD BE MULTIPLE
   LINE SEGMENTS MERGING INTO A SQUALL LINE...EMBEDDED SUPERCELLS CAN
   BE EXPECTED.  DAMAGING WIND THREAT APPEARS TO BE INCREASING...ALONG
   WITH TORNADO THREAT.
