AREAS AFFECTED...TN VALLEY REGION

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 111602Z - 111730Z

THREAT FOR DAMAGING WINDS IS FORECAST TO SLOWLY INCREASE THIS
AFTERNOON...AHEAD OF QUICKLY-MOVING CONVECTIVE LINE.  WW MAY
EVENTUALLY BE REQUIRED.

LATEST RADAR SHOWS A FAIRLY WELL-DEFINED BUT LOW-TOPPED LINE OF
CONVECTION MOVING QUICKLY EWD ACROSS WRN KY/WRN TN/NERN MS.  MORNING
SOUNDINGS REVEAL LITTLE IF ANY INSTABILITY...WITH THE CONVECTIVE
LINE SUSTAINED PRIMARILY BY STRONG FORCING ALONG THE SURFACE FRONT.

AS THE UPPER SYSTEM NOW CROSSING THE OZARKS TAKES ON AN
INCREASINGLY-NEGATIVE TILT...THE SURFACE FRONT -- AND ASSOCIATED
CONVECTIVE LINE -- SHOULD ACCELERATE EWD.  WITH VERY STRONG
DEEP-LAYER WIND FIELD ACROSS THIS REGION...EVEN SLIGHT
INTENSIFICATION OF THE CONVECTIVE LINE WILL INCREASE THE LIKELIHOOD
OF TRANSPORTING STRONGER WINDS TO THE SURFACE.
