   AREAS AFFECTED...KY...NWRN TN
   
   CONCERNING...FREEZING RAIN 
   
   VALID 152034Z - 160030Z
   
   SUMMARY...LIGHT FREEZING RAIN WILL DEVELOP NEWD WITHIN A NARROW
   SW/NE-ORIENTED CORRIDOR FROM WRN TN ACROSS PARTS OF KY. ICE
   ACCUMULATION RATES SHOULD LARGELY HOLD FROM .02-.05 IN/HR.
   
   DISCUSSION...A SWATH OF LIGHT PRECIPITATION CONTINUES TO FALL ACROSS
   THE MID-SOUTH WHERE SUB-FREEZING TEMPERATURES ARE PREVALENT.
   ALTHOUGH THE SURFACE WET BULB FREEZING LINE HAS SLOWLY PROGRESSED
   NWD THROUGH THE DAY...ROUGHLY FROM 30 E MKL-BWG-JKL AS OF
   20Z...MODEL GUIDANCE HAS BEEN PARTICULARLY POOR AT HANDLING THE
   SHALLOW SURFACE-BASED COLD DOME EVIDENT IN THE 18Z BNA RAOB. THIS IS
   ILLUSTRATED BY THE 12Z NAM BEING 10 DEG F TOO WARM WITH THE 20Z
   SURFACE TEMPERATURE AT HOP AND MINIMAL FREEZING RAIN PROBABILITIES
   DEPICTED IN THE 15Z SREF. AS SUCH...ONGOING FREEZING RAIN ACROSS WRN
   TN WILL SHIFT PRIMARILY NEWD AND LIKELY AFFECT A HOP-LEX CORRIDOR
   THROUGH EARLY EVENING.
