The increasingly close juxtaposition of the 2 aforementioned primary mid-level forcing/temperature advection regimes (the mid level cold front to the west & the warm front to the south) is tightening up the mid-level temperature gradient across east-central NC. This is why radar is suddenly going bananas.
 
They already closed Greenville county Schools for the 1/2 inch they got today! Roads are shite, per several people there, a few got stranded!

We close to done out here in Union County?
 
I live in Greenville and we have great rates but flake size is smallish right now waiting for these two bands to merge overhead hopefully....

It should soon. Snow is definitely much lighter on 264 compared to I-87. It was pretty heavy there but those bands should hit Greenville / ENC soon and continue after it has ended on the west side

Rates should be picking back up shortly, you can see another band beginning to setup through Martin/Pitt/Greene/Wayne on the higher scans.

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.
