   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 325
   CONTINUES.
   
   SCATTERED VIGOROUS THUNDERSTORMS ARE ONGOING ALONG AND TO THE LEE OF
   THE CENTRAL APPALACHIANS...THROUGH MUCH OF VIRGINIA INTO THE
   DELMARVA AREA...WITHIN A MODERATELY UNSTABLE AIR MASS TO THE SOUTH
   OF A STALLED SURFACE FRONT.  NEW CONVECTIVE DEVELOPMENT APPEARS TO
   BE TAKING PLACE ACROSS NORTH CENTRAL VIRGINIA...NEAR OR JUST
   NORTHEAST OF A DEEPENING LOW CENTER.  THIS FEATURE MAY BE SUPPORTED
   BY AN APPARENT AREA OF ENHANCED LARGE-SCALE FORCING FOR UPWARD
   VERTICAL MOTION...WHICH IS EXPECTED TO SPREAD EAST NORTHEAST OF THE
   MOUNTAINS OF WEST VIRGINIA TOWARD THE WASHINGTON D.C. AREA BETWEEN
   NOW AND 00Z.  AND...THIS SEEMS TO OFFER THE MOST LIKELY FOCUS FOR
   ANY POSSIBLE GROWING/ORGANIZING STORM CLUSTER LATE THIS AFTERNOON
   AND EARLY EVENING...WITHIN MODEST WESTERLY MID-LEVEL FLOW ON THE
   SOUTHERN FRINGE OF THE STRONGER WESTERLIES.
