Bel Air will get another round of snow before the new year begins, according to the National Weather Service.

Snow will start falling overnight Friday through late Saturday afternoon in Harford County, according to the National Weather Service forecast.

Approximately 2 to 4 inches will accumulate, the report said.

The National Weather Service issued a winter weather advisory for the Baltimore-Washington area—including Harford, northern Baltimore, Carroll and Frederick—from 3 a.m. to 6 p.m. Saturday. A winter weather advisory means that snow-covered roads and limited visibilities may make travel difficult.

Travel conditions Friday evening through Saturday will be "hazardous," the National Weather Service reported.
