Special Weather Statement issued December 23 at 9:02PM EST by NWS Baltimore MD/Washington DC

Spotty light freezing rain is possible across portions of the
central Shenandoah Valley into the central Virginia Piedmont
Tuesday morning. Although spotty and light, any ice will make
conditions slippery given recent cold weather.

Be prepared for slippery roads. Slow down and use caution while
driving. If you are going outside, watch your first few steps taken
on stairs, sidewalks, and driveways. These surfaces could be icy and
slippery, increasing your risk of a fall and injury.
