AREAS AFFECTED...ERN AND SRN OH/WRN PA/WV
CONCERNING...SEVERE THUNDERSTORM WATCH 671...
VALID 090019Z - 090115Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 671
CONTINUES.
OVERALL SEVERE WEATHER THREAT SHOULD CONTINUE TO DIMINISH THIS
EVENING ACROSS WRN PA. WW WILL BE CANCELLED EARLY.
ADDITIONAL STRONG TO SEVERE STORMS REMAIN POSSIBLE FOR ANOTHER 1-2
HOURS TO THE S OF WW 671 ACROSS SRN OH INTO WV.
REGIONAL RADARS INDICATED A LINE OF TSTMS EXTENDING FROM SWRN NY/
NWRN PA SWWD THROUGH WRN PA TO SRN OH. STABILIZING AIR MASS ACROSS
WRN PA INTO NRN WV WILL CONTINUE TO INHIBIT THE FORWARD SPEED OF
THIS LINE OF STORMS...AND THUS LIMIT THE POTENTIAL FOR ADDITIONAL
STRONG WIND GUSTS AS THIS ACTIVITY PROGRESSES EWD THROUGH WRN PA.
ALTHOUGH AIR MASS HAS ALSO STABILIZED ACROSS SERN OH...INSTABILITY
GRADIENT EXTENDING FROM SWRN OH INTO ERN KY/SWRN WV COMBINED WITH
EFFECTIVE BULK SHEAR OF 30 KT SUGGEST THIS PORTION OF THE LINE
SHOULD REMAIN ORGANIZED FOR ANOTHER 1-2 HOURS PRIOR TO FURTHER
STABILIZATION.
