CONCERNING...TORNADO WATCH 758...759...

VALID 301642Z - 301845Z

...TORNADO THREATS WILL INCREASE ALONG AND EAST OF THE MIDDLE
APPALACHIAN MOUNTAINS. ADDITIONAL TORNADO WATCHES WILL LIKELY BE
REQUIRED IN THE NEXT HOUR...

REMNANTS OF KATRINA ARE LIFTING INTO SRN KY WITH A NARROW ZONE OF
PARTIAL CLEARING SPREADING DOWNSTREAM ALONG THE SPINE OF THE
APPALACHIAN MOUNTAINS. WITH THE STRONGEST SHEAR HOLDING WEST OF THE
HIGHER TERRAIN...ADDITIONAL DESTABILIZATION WILL BE REQUIRED ACROSS
WRN PORTIONS OF VA IN ORDER TO OFFSET SOMEWHAT WEAKER SHEAR
PROFILES.  WITH TIME THIS WILL OCCUR AS TEMPERATURES CONTINUE TO
WARM EAST OF THE MOUNTAINS.  LATEST DIAGNOSTIC DATA CONFIRMS THIS
TREND WITH SIG TOR PARAMETER VALUES SPREADING/INCREASING INTO
PORTIONS OF WCNTRL VA. ALTHOUGH STRONGEST LOW LEVEL BAROCLINICITY
IS EXPECTED TO HOLD OVER THE HIGHER TERRAIN...SIGNIFICANT SELY
COMPONENT WILL HOLD ACROSS THE MIDDLE ATLANTIC REGION MAINTAINING
VERY MOIST LOW LEVEL ENVIRONMENT.

TORNADO WATCHES 758/759 WILL BE REPLACED TO REFLECT THIS EVOLUTION.
