Schools were closed in seven Maryland counties and delayed in others today as a heavy, wet snow fell.
Forecaster Ken Shaver of the National Weather Service said 2 to 4 inches of snow were expected in the Baltimore metropolitan area before the flakes taper off around 7 p.m.
School officials in Baltimore, Harford, Howard, Carroll, Frederick, Cecil and Kent counties gave students the day off because of the weather, and other counties were opening classes late.
Shaver said a low pressure system from the southwest could bring more snow tomorrow with additional rain and snow possible Wednesday and Friday.
State Police Sgt. Dennis Henkel said Phase 2 of the snow emergency plan was in effect in Baltimore city and county. That means motorists must have snow tires, chains or all-weather radials on their vehicles and parking will not be allowed on designated snow emergency routes.
Phase 1, which requires only the proper tires or chains, was put into effect at 6 a.m. in Harford, Carroll, Allegany, Garrett and Washington counties.
