   AND NWRN TN

   CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 

   VALID 252346Z - 260045Z

   PROBABILITY OF WATCH ISSUANCE...80 PERCENT

   SUMMARY...STORMS ARE EXPECTED TO CONTINUE DEVELOPING EWD THROUGH

   NWRN TN. SOME OF THIS ACTIVITY WILL POSE A THREAT FOR MAINLY LARGE
   HAIL AND STRONG TO DAMAGING WIND GUSTS. WW WILL LIKELY BE NEEDED
   SOON.

   DISCUSSION...EARLY THIS EVENING SFC AND RADAR DATA INDICATE A FRONT
   SETTLING SWD THROUGH SRN IL...AND SRN MO. LATEST OBJECTIVE ANALYSIS
   SHOW THE ATMOSPHERE TO BE ONLY MODESTLY UNSTABLE IN THIS REGION WITH
   MLCAPE FROM 500-1000 J/KG. NEVERTHELESS...LLJ WILL GRADUALLY DEVELOP
   EWD IN ASSOCIATION WITH A LEAD SHORTWAVE TROUGH CURRENTLY MOVING

   TO STRONGER CONVERGENCE AND ASCENT EXPANDING EWD WITH
   TIME...CONTRIBUTING TO AN INCREASE IN THUNDERSTORM DEVELOPMENT.

   EAST OF WW 6 BEFORE 0030Z.
