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.
