   SEVERE WEATHER POTENTIAL IN THE FORM OF DAMAGING WINDS FROM
   ORGANIZED CONVECTION PERSISTING THROUGH MIDNIGHT CDT/0600 UTC WILL
   LIKELY REQUIRE A WATCH OVER PARTS OF NRN AL SHORTLY.
   
   A LARGE TSTM COMPLEX ACROSS MIDDLE TN IS LIKELY TO GROW UPSCALE AS
   SIGNIFICANT STORM MERGERS OCCUR IN THE NEXT HOUR OR SO ACROSS GILES
   AND LINCOLN COUNTIES IN SRN MIDDLE TN. THIS SYSTEM HAS THE
   APPEARANCE OF PERSISTING WELL INTO THE NIGHT AS IT DEVELOPS SOUTH
   INTO A VERY WARM BOUNDARY LAYER WHERE LATEST DCAPE VALUES ARE
   INDICATED TO BE WELL OVER 1000 J/KG...SUPPORTING A GREATER CHANCE
   FOR DAMAGING WINDS. OVERALL WARM ADVECTION PATTERN AND HIGH PW
   AIRMASS /1.5-2 INCHES/ WILL ALSO LIKELY RESULT IN LOCALLY HEAVY
   RAINFALL IN AREAS WHERE REGENERATIVE CONVECTION OCCURS OVER THE NEXT
   FEW HOURS.
