   AREAS AFFECTED...SERN IND...NERN KY...SWRN OH...WRN WV
   
   CONCERNING...FREEZING RAIN 
   
   VALID 220524Z - 220930Z
   
   SUMMARY...LIGHT FREEZING RAIN WILL SPREAD ACROSS THE OH RIVER INTO
   SWRN OH OVER THE NEXT FEW HOURS.  FREEZING RAIN RATES SHOULD BE ON
   THE ORDER OF .05 IN PER HOUR.
   
   DISCUSSION...WARM ADVECTION IS BEGINNING TO FOCUS ACROSS THE MIDDLE
   OH VALLEY AS LLJ BEGINS TO SHIFT ACROSS IND/KY TOWARD OH.  LEADING
   EDGE OF PRECIP ALOFT HAS EXPANDED INTO CNTRL OH AND WRN WV BUT
   SUBSTANTIAL SUB CLOUD DRY LAYER WILL REQUIRE A FEW HOURS OF
   MOISTENING BEFORE HEAVIER PRECIPITATION DESCENDS TO THE SFC.  GIVEN
   THE RELATIVELY DRY LOW LEVELS...WET BULBING SHOULD ENSURE FREEZING
   RAIN IS MAINTAINED THROUGH AT LEAST 09Z ACROSS MUCH OF THE REGION. 
   FREEZING RAIN RATES MAY APPROACH OR PERHAPS EVEN EXCEED .05 IN PER
   HOUR.  ICE PELLETS/SNOW MAY BRIEFLY BE NOTED ALONG THE LEADING EDGE
   OF PRECIPITATION...ESPECIALLY ACROSS OH BUT SUBSTANTIAL WARMING
   ALOFT SHOULD ULTIMATELY FORCE CHANGEOVER TO FREEZING RAIN AS
   PROFILES MOISTEN.
