   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 774
   CONTINUES.
   
   WHILE ISOLATED DAMAGING WINDS WILL REMAIN POSSIBLE ACROSS MAINLY ERN
   PORTIONS OF WW AREA...A MORE ORGANIZED SEVERE WEATHER THREAT APPEARS
   TO BE DIMINISHING.
   
   LATEST TRENDS IN REGIONAL RADAR IMAGERY INDICATE A GENERAL DECREASE
   IN STORM COVERAGE AND INTENSITY.  THIS IS LIKELY DUE IN PART TO THE
   GRADUAL COOLING AND STABILIZATION OF THE BOUNDARY LAYER.  ISOLATED
   STRONG TO MARGINALLY SEVERE STORMS WILL REMAIN POSSIBLE FROM PARTS
   OF SERN PA EWD/SEWD INTO CNTRL/SRN NJ AND DE FOR THE NEXT COUPLE OF
   HOURS.  BUT...IN GENERAL IT APPEARS THAT THE POTENTIAL FOR MORE
   ORGANIZED CONVECTION IS DECREASING WITH TIME.
