The storm dumped snow through the Mid-Atlantic region. Freezing rain prompted the federal government to allow workers to arrive up to two hours later than normal Monday or take unscheduled leave.
Power outages were reported in Virginia, parts of West Virginia, Maryland and the metropolitan Washington, D.C., area following freezing rain, wet snow and sleet. More than 15,000 customers in Maryland were without power, where the weight of the ice weakened tree limbs, which damaged power lines and other electrical equipment. Some 109,000 customers were without power in Virginia.
The precipitation will likely begin as sleet, especially south of interstate 66 in Virginia, the District of Columbia and U.S. Route 50 in Maryland.
Conditions will start to deteriorate late Monday evening along I-81 from Hagerstown, Maryland to Harrisonburg, Virginia and also along I-95 from Baltimore to Washington.
That area could accrue an additional 3 to 5 inches of snow on top of what they received Sunday. On Sunday, 9.5 inches fell in northeast MD and 8.5 inches fell close to Westminster, Md.
Commuters need to be mindful during the Tuesday morning rush hour as 1 to 2 inches of snow is possible per hour from daybreak to late morning.
On Monday below-zero temperatures crowned the top of the U.S. from Idaho to Minnesota, where many roads still had an inch-thick plate of ice, polished smooth by traffic and impervious to ice-melting chemicals, making driving much more dangerous.
Three to 5 inches of fresh snow is also possible across south western Pennsylvania in areas just south of Pittsburgh, particularly along I-70 from North Belle, Pa. to Wheeling, OH.
In Philadelphia, 2 to 4 inches of snow is possible Tuesday. Sunday, 8.5 inches fell at the Philadelphia International Airport. New York City will receive anywhere from 1 to 3 inches of snow.
