   A NEW SEVERE THUNDERSTORM WATCH IS POSSIBLE ACROSS PORTIONS OF ERN
   KY/TN AND PERHAPS EXTREME SWRN VA AND WRN NC. THESE AREAS ARE BEING
   MONITORED FOR INCREASING STORM ACTIVITY LATE THIS AFTERNOON.
   
   A BROKEN N-S BAND OF STORMS HAS DEVELOPED OVER THE PAST 1-2 HOURS
   AHEAD OF THE DECAYING/WEAKENING MCS IN WATCH 566. THESE STORMS ARE
   OCCURRING IN A MODERATELY UNSTABLE AIRMASS ON THE EDGE OF THE
   STRONGER CAPPING INVERSION/EML ORIGINATING OVER THE PLAINS/MS
   VALLEY. IT APPEARS THAT THE RECENT DEVELOPMENT MAY BE A RESULT OF
   HEATING AND LARGER SCALE ASCENT ASSOCIATED WITH THE MCV/NRN SHORT
   WAVE TROUGH AIDING IN THE ELIMINATION OF REMAINING INHIBITION.
   STRONGER DEEP-LAYER WLY FLOW RESIDES FARTHER WEST...HOWEVER...AND
   THIS MAY BE LIMITING GREATER STORM ORGANIZATION AT THIS TIME. IF THE
   BELT OF STRONG MID-LEVEL FLOW CAN CATCH UP TO THE ONGOING CONVECTION
   AND DOWNSTREAM AIRMASS CONTINUES TO UNDERGO DESTABILIZATION AHEAD OF
   EXPANDING CONVECTIVE COLD POOL...GREATER STORM
   PERSISTENCE/ORGANIZATION MAY ENSUE. IF THIS PROCESS APPEARS TO BE
   OCCURRING THROUGH THE LATE AFTERNOON OR INTO EARLY EVENING...A WATCH
   WILL BE POSSIBLE.
