   SUPERCELLS WITH HISTORY OF DAMAGING WINDS...ISOLATED
   TORNADOES/FUNNELS...AND VERY HEAVY RAINFALL APPEARS TO BE EVOLVING
   INTO A SMALL MCS ACROSS SOUTHEAST IA NEAR THE FAIRFIELD/MOUNT
   PLEASANT AREAS...ALTHOUGH DISTINCT ROTATIONAL ELEMENTS STILL REMAIN
   WITHIN THIS CLUSTER. WHILE DEEP LAYER SHEAR...AND TO A LESSER EXTENT
   POTENTIAL INSTABILITY...BOTH DECREASE WITH SOUTH EXTENT INTO
   NORTHEAST MO/FAR WESTERN IL...THE ORGANIZED NATURE OF THE EVOLVING
   SMALL MCS MAY BE SUFFICIENT TO CONTINUE THE SEVERE THREAT INTO
