...STRONG THUNDERSTORMS POSSIBLE IN WESTERN MIDDLE TENNESSEE
TOWARD MIDNIGHT...

STRONG TO SEVERE THUNDERSTORMS ARE MOVING INTO FAR WESTERN KENTUCKY
AND EXTREME NORTHWEST TENNESSEE NEAR UNION CITY AT 900 PM CDT. IT
IS QUITE LIKELY THAT THESE STORMS WILL CONTINUE TO MOVE EASTWARD
FOR THE NEXT SEVERAL HOURS AND COULD BEGIN TO AFFECT THE WESTERN
AREAS OF MIDDLE TENNESSEE NEAR THE TENNESSEE RIVER BY 11 PM CDT.

TONIGHTS UPPER AIR SOUNDING AT NASHVILLE SHOWED THE ENVIRONMENT OVER
MIDDLE TENNESSEE SOMEWHAT MORE STABLE THAN THE AREA OVER SOUTHEAST
MISSOURI...WESTERN KENTUCKY AND WEST TENNESSEE.  THEREFORE THE
THUNDERSTORMS WILL MORE THAN LIKELY WEAKEN AS THEY GET CLOSER
TO MIDDLE TENNESSEE LATER TONIGHT BUT SOME OF THE STORMS COULD
STILL REMAIN STRONG PRODUCING SMALL HAIL AND GUSTY WINDS ESPECIALLY
OVER NORTHWEST MIDDLE TENNESSEE AROUND DOVER...CLARKSVILLE AND
WAVERLY.
