AREAS AFFECTED...NWRN GA...MIDDLE/ERN TN...CNTRL KY

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 121632Z - 121730Z

SEVERAL WEAK...BUT NOTABLE UPPER VORT MAXIMA/MCV ARE ROTATING NWD
ALONG ERN PERIPHERY OF DOMINANT UPPER LOW CENTERED NEAR KCI.  THESE
DOWNSTREAM FEATURES ARE PRIMARILY RESPONSIBLE FOR NARROW ELONGATED
ZONE OF GRADUALLY INTENSIFYING CONVECTION FROM NERN AL...NWD INTO
CNTRL KY.  LIGHTNING/RADAR DATA SUPPORT THIS UPWARD EVOLUTION WHICH
IS LIKELY TO CONTINUE WITH ANY BOUNDARY LAYER HEATING OBSERVED INTO
THE AFTERNOON HOURS.  ALTHOUGH SFC DEW POINTS ARE GENERALLY IN THE
LOWER 50S...QUITE COLD MID LEVEL TEMPERATURES...H5 AOB MINUS
20C...WILL OVERSPREAD A N-S ZONE OF LOW LEVEL CONFLUENCE IN THE
AFOREMENTIONED AREA ENHANCING THE PROSPECTS FOR GRADUALLY
INTENSIFYING/SUSTAINING DEEPENING CONVECTION...ESPECIALLY GIVEN THAT
STRONGEST LLJ WILL REFOCUS OVER TN/KY DURING THE 18-21Z TIME FRAME.
ORGANIZED LINE SEGMENTS THAT MANAGE TO BECOME ELONGATED A BIT NW-SE
ACROSS THIS REGION COULD PRODUCE DAMAGING WIND GUSTS.  WILL CONTINUE
TO MONITOR THIS REGION.
