AREAS AFFECTED...ECNTRL NY...ERN PA...FAR NRN MD AND WRN NJ

CONCERNING...SEVERE THUNDERSTORM WATCH 850...

VALID 061958Z - 062130Z

SEVERAL LINES OF STRONG TO SEVERE THUNDERSTORMS WILL CONTINUE TO
MOVE RAPIDLY ENEWD INTO THE ERN PARTS OF TORNADO WATCH 850. A NEW WW
WILL LIKELY BECOME NECESSARY EAST OF THE CURRENT TORNADO WATCH
WITHIN THE NEXT 1-2 HOURS.

A VIGOROUS UPPER-LEVEL TROUGH OVER THE GREAT LAKES AND AN ASSOCIATED
90 KT MID-LEVEL JET MAX OVER OH WILL MOVE QUICKLY NEWD INTO THE
APPALACHIAN MTNS THIS AFTERNOON. THE LEADING BAND OF ASCENT IS
MOVING ACROSS WRN PA AND IS ENTERING WRN NY ATTM. THIS IS SUPPORTING
SEVERAL CONVECTIVE LINES MOVING EWD ACROSS THE REGION. VISIBLE
SATELLITE IMAGERY SHOWS CLEARING SKIES AHEAD OF THE LINE IN CNTRL PA
AND PARTIAL CLEARING IN SW NY. AS A RESULT...DESTABILIZATION WILL
CONTINUE AHEAD OF THE LINE ALLOWING THE STORMS TO REMAIN INTENSE
THROUGH THIS AFTERNOON INTO THIS EVENING. THE STRONGLY SHEARED
ENVIRONMENT AND INCREASING INSTABILITY WILL SUSTAIN THE SUPERCELL
POTENTIAL. ALTHOUGH AN ISOLATED TORNADO THREAT WILL LIKELY
CONTINUE...THE PRIMARY THREAT WILL BE WIND DAMAGE AND HAIL. A NEW WW
WILL LIKELY BE NEEDED AS THE CONVECTION CONTINUES TO MOVE EWD THIS
AFTERNOON.
