BALTIMORE, MD — The snow totals are in from the National Weather Service, which received unofficial data from its employees as well as emergency management personnel, trained spotters and media. At the end of the day, Westminster reported the highest accumulation in the Baltimore-Washington area; 6.5 inches of snow were measured there on Saturday, Dec. 9, according to the weather service. There was also a report of 6.5 inches in Ridge from St. Mary's County in southern Maryland Sunday morning.
