CONCERNING...TORNADO WATCH 50...

VALID 082332Z - 090030Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 50 CONTINUES.

TORNADO WATCH 50 COULD BE EXTENDED LOCALLY FOR ANOTHER HOUR OR TWO
ACROSS PARTS OF SOUTH CENTRAL KENTUCKY.  BUT...AN ADDITIONAL WW IS
NOT ANTICIPATED.

VIGOROUS DEEP CONVECTION PERSISTS ALONG A PRE-FRONTAL WIND SHIFT
...ASSOCIATED WITH THE LEADING EDGE OF STRONGER LOWER/MID
TROPOSPHERIC COOLING ACCOMPANYING THE STRONG SHORT WAVE TROUGH
LIFTING INTO THE GREAT LAKES.  ALTHOUGH THE UPPER IMPULSE IS PROGGED
TO TAKE A MORE EASTWARD TURN TOWARD THE LOWER GREAT LAKES/UPPER OHIO
VALLEY REGION LATER THIS EVENING...STRONGER MID/UPPER FORCING FOR
UPWARD VERTICAL MOTION NOW APPEARS LIKELY TO REMAIN NORTH/EAST OF
THE TENNESSEE VALLEY.  LIGHTNING DATA SUGGEST A GENERAL WEAKENING
TREND TO ONGOING STORMS...AND THIS SEEMS LIKELY TO CONTINUE AS
SOUTHEASTERLY STORM RELATIVE INFLOW EMANATES FROM A LESS
MOIST/PROGRESSIVELY MORE STABLE LOW-LEVEL ENVIRONMENT ACROSS
MIDDLE/EASTERN TENNESSEE AND SOUTHEAST KENTUCKY.  BUT...FAST MOVING
STRONGER CELLS EMBEDDED WITHIN A 50-60 KT WESTERLY DEEP LAYER MEAN
FLOW REGIME MAY MAINTAIN AT LEAST THE RISK FOR POTENTIAL DAMAGING
SURFACE GUSTS INTO THE 00-02Z TIME FRAME.
