MD 0053 CONCERNING HEAVY SNOW FOR CENTRAL AND EASTERN PORTIONS OF THE CAROLINAS
Mesoscale Discussion 0053
NWS Storm Prediction Center Norman OK
0801 PM CST Tue Jan 21 2025
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.
