Cold air was in place east of the Blue Ridge Mountains on the 29th and 30th, keeping surface temperatures below freezing. Low pressure moved from the Lower Mississippi Valley northeastward to the Mid-Atlantic region early on the 30th, creating the perfect conditions for freezing rain across South Central Maryland, a mix of sleet and snow in North Central Maryland, and moderate snowfall from Carroll County westward. Ice accumulations between 1/4 and 1 inch coated roads, trees, and power lines in St. Mary's, Charles, and Calvert Counties.  Electrical outages were reported as trees and branches weighed down by ice fell onto power lines.  Disruptions affected 1700 customers in Prince George's and Charles Counties, 4000 customers in Anne Arundel County, 600 customers in Baltimore, 2200 customers in Calvert County, and 4100 customers in St. Mary's County.  St. Mary's County officials had to remove 60 downed trees after the storm.  A mix of sleet, freezing rain, and snow fell across Prince George's and Anne Arundel Counties.  Snow and sleet accumulations in this area ranged from 1 to 3 inches.  Elsewhere 3 to 10 inches of snow and sleet fell.  Storm total snow/sleet accumulations included 4.0 inches in Baltimore and Bel Air, 2 to 3 inches at Baltimore/Washington International Airport (BWI), 1 to 2 inches in Annapolis, 7.0 inches in Gaithersburg, 1.0 inch in Oxon Hill, 9.3 inches in Westminster, 10.0 inches in Frederick, 7.9 inches in Hagerstown, 5.0 inches in Cumberland, and 5.1 inches in Frostburg.  Several traffic accidents were reported across the area, including one wreck which claimed the life of a 45-year-old woman on the Baltimore-Washington Parkway.  One hospital in Anne Arundel County treated 25 people for car accident related injuries, 12 patients for slip and fall injuries, and 20 patients reporting heart-related problems, most likely due to shoveling snow.  Passengers at both BWI and on commuter trains reported travel delays.
