A clipper system from Canada, similar to the one that brought 3 inches of snow to Baltimore County earlier this month, is expected to dust the county with between 1 to 3 inches, according to National Weather Service meteorologist Heather Scheffield at the Weather Forecast Office in Sterling, Va.
"Snow should be intensifying across the area through the next few hours," Scheffield said at 1 p.m.
The National Weather Service issued a winter weather advisory on Tuesday for the region, which is in effect until 6 p.m.
The snow prompted the Baltimore County Public School System to close schools an hour early and cancel after-school activities. In addition, the Southwest Area Education Advisory Council canceled a meeting at Westowne Elementary School in Catonsville, scheduled for 6:30.
The school board meeting has been rescheduled for Wednesday, Jan. 28 at 5 p.m. The meeting will be held in room 114 of Building E of the board's Greenwood Campus at 6901 Charles Street in Towson, said a statement from the public school system.
Baltimore County's Department of Public Works has 482 personnel and 388 pieces of equipment deployed countywide, said Lauren Watley, a county spokeswoman.
"Currently crews are out countywide monitoring conditions," Watley said. "At this point it is just monitoring until we have enough accumulation to begin salting and plowing roads."
Watley urged evening commuters to use caution and common sense while driving home from work.
Temperatures in the county are expected to drop into the 20s Wednesday night, which could cause ice to form on roads, Scheffield said.
Residents can expect higher temperatures and dry weather on Thursday and Friday. However, another coastal low-pressure system reaching the area on Saturday could bring additional snowfall, Scheffield said.
