AREAS AFFECTED...SERN PA / NRN DE / MD / NRN VA

CONCERNING...SEVERE THUNDERSTORM WATCH 764...

VALID 200028Z - 200200Z

STORMS CONTINUE ACROSS WW...ALTHOUGH A WEAKENING TREND HAS BEEN
NOTED OVER THE PAST HOUR OR SO.  LOCAL SEVERE THREAT CONTINUES.

EVENING IAD RAOB INDICATES FAVORABLE INSTABILITY / SHEAR...BUT CAP
IS INDICATED...WHICH WILL CONTINUE TO INCREASE AS LOW-LEVEL AIRMASS
STABILIZES WITH THE LOSS OF DAYTIME HEATING.  THIS IS LIKELY
CONTRIBUTING TO A SLOW WEAKENING TREND WITH ONGOING CONVECTION WHICH
SHOULD CONTINUE OVER THE NEXT ONE TO TWO HOURS.

IN THE MEAN TIME...ENVIRONMENT SUPPORTS A CONTINUED THREAT FOR HAIL
/ LOCALLY DAMAGING WINDS WITH ONGOING STORMS...PARTICULARLY ACROSS
SRN PORTIONS OF WW WHERE GREATEST INSTABILITY REMAINS.
