Winter Storm Dion is not done with the East Coast yet. It's delivering a parting shot of quick, heavy snow along the I-95 corridor Tuesday, snarling traffic and flights as snow falls at the rate of 1-2 inches an hour.

“Dion is barreling in like a freight train," said The Weather Channel's winter weather expert Tom Niziol. "The good news is it's a very quick storm. By mid-afternoon the Northeast will improve and by the evening commute, Dion will be leaving Boston.”

Washington D.C., Baltimore, Philadelphia, and New York got roughly 1-3 inches of snow Tuesday morning. Some interior parts of the Northeast received as much as 5 inches. While not major accumulations, the snow fell so quickly in some areas that it created a nightmare on the roads during the morning commute.

"We have about 1.6 inches of snow, officially, at Baltimore-Washington Airport, which is actually more than New York City or Boston has seen this season," said The Weather Channel meteorologist Jim Cantore, reporting from Baltimore.

The federal government is closed for a second day for non-emergency workers. Other employees are expected to telecommute Tuesday. All Washington D.C. area schools are closed as well.
