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.
