   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 274 CONTINUES.

   SUMMARY...RISK FOR DAMAGING WINDS AND A COUPLE TORNADOES REMAINS
   OVER SRN PORTIONS OF VALID WW. NRN PORTION APPEARS UNLIKELY TO
   SUFFICIENTLY DESTABILIZE AND IS RECOMMENDED FOR LOCAL CANCELLATION
   PRIOR TO 00Z WW EXPIRATION.

   DISCUSSION...RADAR TRENDS SUGGEST NRN PORTION OF A QLCS OVER CNTRL
   NY HAS WEAKENED SUBSTANTIALLY OVER THE PAST HOUR. THIS APPEARS TO BE
   A FEW HOURS FASTER THAN INDICATED IN CONSENSUS OF DETERMINISTIC
   CAMS. 18Z ALB RAOB SAMPLED A DEARTH OF INSTABILITY WITH MEAGER
   MUCAPE NEAR 200 J/KG. WITH 1-MIN VISIBLE SATELLITE IMAGERY
   INDICATING CLOUD BREAKS ONLY AS FAR N AS MONTGOMERY COUNTY NY...IT
   APPEARS QUITE UNLIKELY THAT CONVECTION WOULD SUBSTANTIALLY
   RESTRENGTHEN N OF THE MOHAWK VALLEY. ANY APPRECIABLE
   TORNADO/DAMAGING WIND RISK SHOULD LIE FROM PARTS OF SRN NY SWD INTO
   NERN PA WHERE INSTABILITY IS GREATER AMIDST ENLARGED HODOGRAPHS AS
   SAMPLED BY BGM VWP DATA.
