WW MAY BECOME NECESSARY FOR PARTS OF ERN TN/ERN AL INTO WRN/CENTRAL
GA.
ASCENT ATTENDANT TO UPPER TN VALLEY SHORT WAVE TROUGH AND VORTICITY
LOBE EXTENDING SWD THROUGH ERN AL/WRN GA WILL CONTINUE TO SUPPORT
TSTM DEVELOPMENT FROM ERN TN/ERN AL INTO GA DURING THE LATE
AFTERNOON AND EARLY EVENING. SWLY LOW LEVEL FLOW FROM SRN AL INTO
CENTRAL GA HAS AIDED IN MOISTURE INFLUX INTO THIS REGION...WHILE
PLUME OF STEEP MID LEVEL LAPSE RATES SPREADS EWD WITHIN STRONG
/50-60 KT/ WLY FLOW ALOFT...AND ATOP MOISTURE RETURN. THESE WIND
FIELDS ARE SUPPORTING DEEP LAYER SHEAR AROUND 50 KT. THIS COMBINED
WITH MARGINAL INSTABILITY SUGGESTS A FEW STRONGER CORES WILL POSE A
POTENTIAL FOR ORGANIZATION AND A THREAT FOR HAIL AND STRONG WIND
GUSTS. ALTHOUGH TSTM COVERAGE IS SOMEWHAT LOW AT THIS POINT...
FURTHER DESTABILIZATION INTO THE EVENING MAY SUPPORT GREATER TSTM
DEVELOPMENT.
