   MONITORING FOR A WATCH ACROSS EASTERN PORTIONS OF AR INTO WESTERN
   TN/NORTHERN MS.
   
   WITH A CURRENT FORWARD MOVEMENT OF AROUND 40-45 KT...AN ONGOING
   WELL-ORGANIZED QUASI-LINEAR CONVECTIVE SYSTEM /WITH AN EMBEDDED BOW/
   IS EXPECTED TO CONTINUE TO STEADILY PROGRESS EAST-NORTHEASTWARD
   TODAY INTO PORTIONS OF WESTERN TN/NORTHERN MS. DAMAGING WINDS AS
   WELL AS SOME HAIL/ISOLATED TORNADO POTENTIAL ARE EXPECTED TO BECOME
   INCREASING CONCERN THROUGH THE LATE MORNING/EARLY AFTERNOON
