   ROTATION WITH THE POTENTIAL FOR TORNADOES. THESE STORMS ARE
   APPROACHING THE ERN EDGE OF THE INSTABILITY AXIS...WITH A MORE
   MARGINAL THERMODYNAMIC ENVIRONMENT NOTED DOWNSHEAR IN THE 24/00Z BNA
   SOUNDING. HOWEVER...VERY STRONG DEEP-LAYER WIND PROFILES AND A

   WILL SHIFT PRIMARILY INTO MIDDLE TN AND NWRN AL OVER THE NEXT HR OR
   SO. A LINGERING THREAT COULD EXTEND PAST 02Z ACROSS PARTS OF NRN MS
   WITH NEW TSTM DEVELOPMENT...AND THIS SCENARIO WILL CONTINUE TO BE
   MONITORED.
