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

   Concerning...Heavy snow 

   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.
