   Areas affected...Ohio River Valley

   Concerning...Winter mixed precipitation 

   Valid 032255Z - 040300Z

   SUMMARY...Moderate to heavy mixed winter precipitation will likely
   continue for the next several hours through the greater Ohio River
   Valley region.

   DISCUSSION...Surface observations and MPING reports along much of
   the OH River Valley show a variety of precipitation types at the
   surface, including freezing rain, sleet, and moderate to heavy snow.
   The transition zone from mostly rain to frozen hydrometeors remains
   fairly narrow with temperatures in the mid 30s noted in far
   southeast OH and southern KY, quickly falling into the upper 20s in
   central OH and southern IN. Latest RAP forecast soundings maintain a
   persistent warm nose between 850 to 700 mb through the early evening
   hours with only slight cooling with time. This is largely due to
   continued warm advection along a tight mid-level baroclinic zone
   draped over the region. Lift within this baroclinic zone and ahead
   of the upper-level trough will continue through at least 02-04 UTC,
   which should maintain areas of moderate to heavy mixed precipitation
   for the next several hours.
