Areas affected...northern Georgia...eastern Tennessee...far western
South Carolina...western North Carolina

Concerning...Winter mixed precipitation=20

Valid 102130Z - 110030Z

SUMMARY...Areas of moderate to heavy snowfall along the high terrain
and mixed precipitation likely in the afternoon/evening across
portions of east TN/north GA and western SC/NC.

DISCUSSION...A broad region of heavy precipitation continues to
shift northward across northern Alabama into eastern
Tennessee/northern Georgia beneath enhanced mid-level flow and
forcing from an upper-level trough. This precipitation shield will
continue to lift north and eastward this evening, bringing an
increase in the precipitation rates across the region, extending
into western North Carolina through time. Moderate to heavy snowfall
will be possible (with occasional 1" hr rates) across the southern
Appalachian Mountains in eastern Tennessee. Further south across
northern Georgia into the western Carolinas, profiles will continue
to support additional accumulations of freezing rain. NAM/RAP
sounding analysis across northern Georgia into South Carolina show a
warm nose at 850 mb with surface observations indicating
temperatures remain in the upper 20s to 30s. Occasionally, mixed precipitation/sleet will be possible.
