From Blacksburg NWS
Now for what everyone really cares about: snow and ice totals. Due
to the cold air in place and already cold ground temperatures, any
snow that does fall will be light and fluffy and accumulate quickly.
The initial onset of snow will cause 2-4" of snow to fall
along/south of the NC/VA border, increasing to 5-8" along US-460.
Northern areas along I-64 will see 10-14"+ of snow, with locally
higher amounts possible. On top of the snow will be sleet
accumulations, possibly measured in inches as well. Around 1-3" of
sleet could accumulate due to the very cold surface temperatures on
top of the snow. If the sleet starts sooner, the snow totals will
also decrease. Finally, ice accumulations will be light along/west
of the Blue Ridge and north of I-64, with anywhere from a glaze to
two tenths possible. For the Piedmont, 0.25-0.40" is expected,
mainly Sunday afternoon/evening. The ice will add a crusty hard
layer on top of the snow/sleet.
With all of the above being said, take this storm seriously and
prepare now. Due to the storm having mixed precipitation types,
roads will be harder to clear, causing travel to be difficult and
dangerous. If at all possible, avoid travel unless absolutely
necessary. With the slightly later timing of the storm, Monday
morning`s commute will be treacherous, especially with very cold
temperatures keeping all fallen precipitation from melting.
