Amounts are less to the east in Orange and Spotsylvania county, but up to 1-3” more could fall before the band shifts east this afternoon. Farther east, a couple inches of snow are possible in Virginia’s northern neck into southern Charles and St. Mary’s county, where a winter weather advisory is in effect.

Upper level disturbance (or vorticity maximum) at 10 a.m. this morning (per NAM model) tracking across the Virginia-North Carolina border. The heaviest precipitation usually sets up just north of such a disturbance and has done so today over central Virginia. (StormVistaWxModels.com)

The cause of the snow is a clipper system zipping through the southern mid-Atlantic. The heaviest precipitation with such a clipper usually sets up in a narrow band just north of the track of the upper level disturbance (shown to the right). Central Virginia has coincided with this sweet spot for lift and spin in the atmosphere.
