   CONCERNING...SEVERE THUNDERSTORM WATCH 755...
   
   VALID 092307Z - 100030Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 755
   CONTINUES.
   
   SPORADIC POTENTIAL FOR LOCALIZED DAMAGING WINDS SHOULD EXIST FOR THE
   NEXT FEW HOURS...BUT OVERALL SEVERE POTENTIAL APPEARS TO BE WANING
   AND THE NEED FOR AN ADDITIONAL WW BEYOND 01Z SCHEDULED EXPIRATION
   APPEARS UNLIKELY ATTM.
   
   SCATTERED TSTMS FROM THE ADIRONDACK MTNS SWD TO THE ERN MD SHORE
   SHOULD POSE AN ISOLATED RISK FOR WET MICROBURSTS THROUGH AROUND 
   01Z. HOWEVER...OVERALL SEVERE THREAT SHOULD WANE. THIS IS LIKELY DUE
   TO SHORT WAVE IMPULSE SHIFTING NEWD ACROSS NRN NY AND ASSOCIATED
   FORCING ASCENT DIMINISHING THROUGH THE EVENING...AS WELL AS THE LACK
   OF GREATER DESTABILIZATION IN THE WAKE OF EARLY AFTERNOON
   CONVECTION. WITH TEMPERATURES ALREADY COOLING THROUGH THE 70S IN
   MOST OF THE WW AREA...THE GREATEST RELATIVE SHORT-TERM SEVERE THREAT
   LIKELY WILL EXIST ALONG THE SRN PERIPHERY AND S OF THE WW FROM SRN
   NJ INTO DE/ERN MD WHERE LOW-LEVEL LAPSE RATES ARE STEEPEST.
