SEVERE THREAT IS GRADUALLY DIMINISHING.

WATER VAPOR IMAGERY INDICATES THAT SHORTWAVE TROUGH WAS MOVING FROM
WV INTO PA AND MOST OF THE LIFT ASSOCIATED WITH THIS SYSTEM WAS
LIFTING NWD INTO PA AND NY. ALTHOUGH A NARROW LINE OF STORMS WAS
LOCATED ALONG THE COLD FRONT FROM SE OF DCA TO EAST OF RWI...THE
WEAKENING FORCING AND MARGINAL INSTABILITY HAS RESULTED IN THE STORM
INTENSITIES TO DECREASE DURING THE PAST HOUR.  ALTHOUGH AN ISOLATED
WIND SEVERE WIND GUST IS POSSIBLE WITH THE LINE...EVENING SOUNDINGS
SHOWED A STABLE BOUNDARY LAYER AND GIVEN THE WEAK INSTABILITY...IT
LIKELY WILL BECOME DIFFICULT FOR THE STRONG/SEVERE DOWNDRAFTS TO
REACH THE SURFACE.
