   VALID 222048Z - 222215Z
   
   SPORADIC DAMAGING WINDS AND LARGE HAIL WILL BE POSSIBLE ACROSS THE
   REGION LATE THIS AFTERNOON.  AN ADDITIONAL SEVERE THUNDERSTORM WATCH
   DOWNSTREAM INTO CNTRL KY IS POSSIBLE.
   
   LINEAR MCS HAS PULSED TO SVR LEVELS SINCE IT INITIATED OVER MO...BUT
   HAS HAD A DIFFICULT TIME PRODUCING WIDESPREAD SVR WEATHER.  THIS IS
   PROBABLY DUE TO THE FACT THAT IT HAS REMAINED SLIGHTLY ELEVATED AND
   IS REMOVED ENOUGH FROM THE STRONGER INSTABILITY AND STRONGEST LLJ TO
   REMAIN MOSTLY SUB-SEVERE.
   
   STORMS WILL CONTINUE TO FORM PREFERENTIALLY ALONG THE SRN FLANK OF
   THE LINE INTO CNTRL KY THROUGH LATE AFTERNOON WHERE RESERVOIR OF
   STRONGER INSTABILITY WILL CONTINUE.  DEEP LAYER WIND FIELDS WILL
   REMAIN CONDUCIVE FOR ORGANIZED SVR STORMS...BUT DOWNSTREAM INFLOW
   WILL REMAIN WEAK TO SUPPORT A WELL-SUSTAINED BOWING COMPLEX.
