Areas outside of D.C. and Baltimore were slammed with at least a foot of snow overnight.
The storm hit Philadelphia at midnight, dumping more than 8 inches by Thursday morning, while New York City had two inches by 7 a.m. The city is expected to be hit with around 8 inches before the end of the day, with more than a foot predicted in parts of the tri-state area, the National Weather Service said.
Visibility also will be hindered by 20 mph winds gusting up to 35 mph.

Tom Niziol, The Weather Channel's winter weather expert, warned that while East Coast cities will see the snow turn into rain by the afternoon, the tail end of the storm will bring another blast of snow.
He added that Thursday's high will be more than 30 degrees along the coast, which means it will be too warm to see a repeat of the same vicious ice storm that plagued the South on Wednesday.
But the snow will be a major headache for travelers in the Northeast, already battered by a messy winter season, Roth said.
Communities "may have enough plows to deal with normal storms but with two inches an hour … the snow just builds back up," he added. "This will affect any roadways or airport runways in the region."
