   AREAS AFFECTED...CNTRL-ERN TX/FAR NE AL/NRN GA
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 102050Z - 102245Z
   
   LINEAR MCS WILL CONTINUE TO TRACK ESEWD. ISOLATED HAIL AND/OR
   DAMAGING WINDS WILL BE POSSIBLE WITH EMBEDDED CELLS WITHIN THE LINE.
    WW MAY BE NECESSARY ACROSS CNTRL TN/NRN AL/NRN GA WITHIN THE NEXT
   HOUR OR SO.
   
   STRONG TO SEVERE CONVECTIVE LINE WAS MOVING ESEWD ALONG A LOW-LEVEL
   MOISTURE GRADIENT STRETCHING FROM CNTRL TN SEWD INTO CNTRL GA.
   INSTABILITY WAS STRONG S OF THE LINE WITH ANALYSIS SHOWING MLCAPE
   VALUES AROUND 2000 J/KG...THOUGH EAST OF THE LINE INTO ERN TN
   INSTABILITY REMAINS MARGINAL. ALTHOUGH DEEP LAYER SHEAR WAS WEAK IN
   THIS REGION...THE LOW-LEVEL JET...CURRENTLY ALONG THE MS RIVER
   VALLEY WILL BEGIN TO SHIFT EWD OVER THE NEXT FEW HOURS INCREASING
   THE LOW-LEVEL SHEAR AND ADVECTING LOW-LEVEL MOISTURE NEWD TOWARD THE
   LINE. THE INSTABILITY AND INCREASING LOW-LEVEL FLOW WILL LIKELY
   INCREASE THE INTENSITY OF THE LINE AND DAMAGING WINDS WILL BE
   POSSIBLE WITH EMBEDDED BOW ECHOES. HAIL IS ALSO POSSIBLE WITH THE
   STRONGER INSTABILITY IN THE SW PART OF THE LINE WHERE INSTABILITY IS
   THE STRONGEST. ACTIVITY MAY BEGIN TO TURN MORE SOUTH OF EAST AND
   PROPAGATE ALONG INSTABILITY GRADIENT INTO THE SRN APPALACHIANS.
