VALID 211555Z - 211700Z

WELL DEFINED UPPER VORT IS JUXTAPOSED WITH SFC LOW OVER NCNTRL
AR...JUST NORTH OF LIT.  THIS FEATURE IS SHIFTING EAST AT ROUGHLY
25KT WITH A WELL PRONOUNCED DRY SLOT SPREADING AHEAD OF WIND SHIFT
ACROSS ERN AR/WRN MS INTO WRN TN.  ALTHOUGH SFC TEMPERATURES ARE NOT
THAT WARM...SFC-3KM LAPSE RATES HAVE STEEPENED SIGNIFICANTLY...AOA 7
C/KM...JUST AHEAD OF SFC LOW WHICH APPEARS TO BE ENHANCING
LOW-TOPPED CONVECTION ALONG ADVANCING BOUNDARY.  SHEAR PROFILES
STRONGLY SUPPORT ROTATING UPDRAFTS AND IT IS BECOMING INCREASINGLY
LIKELY THAT SUPERCELLS WILL EVOLVE WITH TIME.  HAIL SHOULD CERTAINLY
ACCOMPANY THE STRONGER STORMS AND GIVEN THE MOIST BOUNDARY
LAYER...AND EXPECTED LOW LCL/CLOUD BASES...A FEW TORNADOES MAY ALSO
DEVELOP WITH STRONGER STORMS.  TORNADO WATCH WILL LIKELY BE REQUIRED
OVER THIS REGION BY 18Z.
