   Areas affected...Northeast GA into parts of SC

   Concerning...Winter mixed precipitation 

   Valid 101350Z - 101745Z

   SUMMARY...Winter mixed precipitation may increase through the
   morning.

   DISCUSSION...The eastern portion of an extensive precipitation
   shield is currently spreading across northeast GA into parts of SC.
   Evaporative cooling and saturation of an initially dry column (as
   noted on the 12Z CHS sounding) will allow for some increase in
   winter precipitation rates through the morning. As initial
   saturation occurs, occasionally moderate snow and/or sleet rates may
   develop (as noted in upstream observations), though there may be
   some tendency toward a liquid precipitation phase and freezing-rain
   potential with time and eastward extent, as warm advection above the
   surface continues to increase. Some ice accretion will be possible
   where near-surface cold/dry advection allows subfreezing
   temperatures to persist through the remainder of the morning into
   early afternoon.
