AREAS AFFECTED...SERN OH / WRN WV / ERN KY / ERN TN

CONCERNING...SEVERE THUNDERSTORM WATCH 53...

VALID 101016Z - 101115Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 53
CONTINUES.

SUMMARY...THE THREAT FOR LOCALIZED DAMAGING WIND GUSTS CONTINUES TO
THE EAST OF THE BROKEN SQUALL LINE ACROSS PORTIONS OF THE UPPER OH
VALLEY AND UPPER TN VALLEY BUT THIS THREAT WILL LIKELY BECOME
INCREASINGLY LOCALIZED.

DISCUSSION...RADAR MOSAIC SHOWS A FRACTURED PRE-FRONTAL SQUALL LINE
MOVING ENEWD AROUND 45-50 KT.  THE STRONG WIND FIELD IN PLACE WILL
SUPPORT SOME POSSIBILITY FOR A STRONGER DOWNDRAFT TO BE CAPABLE OF
STRONG TO LOCALLY DAMAGING WIND GUST VIA MOMENTUM TRANSPORT.
NONETHELESS...IT APPEARS THE FAST ENEWD MOTION OF THE CONVECTIVE
LINE WILL LARGELY OUTRUN THE ABILITY FOR THE AIRMASS TO DESTABILIZE
SUFFICIENTLY TO THE E OF THE EXISTING SEVERE THUNDERSTORM WATCH.
WHILE A STRONG WIND GUST OR TWO IS POSSIBLE DOWNSTREAM OF THE SEVERE
WATCH TOWARDS DAYBREAK...THE INCREASINGLY MARGINAL THERMODYNAMIC
ENVIRONMENT SHOULD LIMIT THE COVERAGE OF A POSSIBLE WIND DAMAGE
THREAT.  THEREFORE AT THIS TIME...AN ADDITIONAL SEVERE WATCH IS NOT
ANTICIPATED FOR ERN WV SWWD THROUGH SW VA AND FAR ERN TN.
