   VALID 140123Z - 140300Z
   
   TRENDS HAVE BEEN FOR STORMS TO WEAKEN IN TN PORTION OF WW 462. OTHER
   STORMS HAVE INTENSIFIED ACROSS NRN KY AND THESE STORMS WILL HAVE THE
   GREATEST SEVERE POTENTIAL NEXT 2 HOURS OR SO. ISOLATED DAMAGING WIND
   AND LARGE HAIL WILL BE THE MAIN THREATS.
   
   GIVEN STABILIZING EFFECTS ASSOCIATED WITH COOLING BOUNDARY
   LAYER...IT IS PROBABLE THAT STORMS OVER TN WILL NOT REINTENSIFY.
   OBJECTIVE ANALYSIS SHOWS THE STRONGEST INSTABILITY ACROSS CNTRL/ERN
   KY WITH MLCAPE FROM 1500 TO 2000 J/KG AND VERTICAL SHEAR SUFFICIENT
   FOR ORGANIZED STORMS INCLUDING SUPERCELLS. SEVERE THREAT WITH THIS
   ACTIVITY MAY PERSIST FOR ANOTHER COUPLE HOURS AS IT MOVES NEWD
   THROUGH AXIS OF INSTABILITY.
