Areas affected...central and eastern portions of the Carolinas

Concerning...Heavy snow=20

Valid 220201Z - 220700Z

SUMMARY...Moderate to heavy snow should gradually become widespread
through early tonight across portions of the central and eastern
Carolinas.

DISCUSSION...700 mb warm-air and moisture advection are increasing
over central and eastern parts of the Carolinas with the approach of
a pronounced 500 mb trough that is traversing the central
Appalachians. Beneath the 700 mb moistening, strong surface-850 mb
cold-air advection is contributing to further saturation and
sensible cooling of the column to support a predominance of snow,
which is currently being indicated by surface observations on a
widespread basis. Ahead of the upper trough, 700 mb frontogenesis is intensifying, which should support increased snowfall rates. As
such, in addition to the transition to snow, 0.5-1.0 inch/hour
snowfall rates may develop over the next couple of hours, as also
suggested by some of the latest high-resolution guidance runs.
