   CONCERNING...FREEZING RAIN
   
   VALID 111126Z - 111730Z
   
   ...AREA OF FREEZING RAIN WILL SPREAD ACROSS NRN OH/WRN PA OVER
   THE NEXT FEW HOURS...
   
   FZRA HAS ALREADY SPREAD INTO CNTRL OH...WITH SOME SLEET/SNOW
   MIXED AROUND THE COLUMBUS AREA. WITH CURRENT DEWPOINTS ONLY IN
   THE TEENS...IT MAY TAKE A FEW HOURS TO SATURATE IN WRN PA...WHICH
   WILL DELAY THE ONSET OF PCPN. SNOW HAS MAINLY BEEN OBSERVED
   UPSTREAM IN CNTRL IN...AND COOLER AIR AT 850MB WILL MOVE INTO THE
   AREA BETWEEN 15-18Z. THIS MAY CHANGE PRECIPITATION IN WRN OH TO
   SNOW BY LATER THIS MORNING. RUC PTYPE ALGORITHM/FORECAST
   SOUNDINGS SUPPORT THIS SCENARIO. HOWEVER...THE DOMINANT
   PRECIPITATION TYPE WILL BE FREEZING RAIN ACROSS THE DISCUSSION
   AREA.
