(CBS/AP) A storm expected to begin Tuesday could dump a foot or more of snow on parts of the Mid-Atlantic that got two feet over the weekend.
National Weather Service forecaster Bruce Sullivan says the next storm is expected to begin late Tuesday afternoon and run through midday Wednesday.
The most significant snowfall is expected across the northern Mid-Atlantic region, including central northern Maryland and northern Delaware and parts of New Jersey and Pennsylvania.
Sullivan says the storm will also bring wind, which could cause considerable blowing and drifting of the snow and hamper cleanup efforts under way.
The snow is expected to stick around for a while.
Sullivan says they "don't really see any warm weather in sight to melt it."
Meanwhile, scores of workers in the Mid-Atlantic region were given Monday off to shovel out from a blizzard that buried some areas in nearly 3 feet of snow.
Federal agencies that employ 230,000 in Washington will be closed Monday, as will many businesses and school districts across the region.
CBS News correspondent Nancy Cordes reports that Washington's snow removal crews have been working 12 hour shifts since Friday to move the white stuff, but their efforts were no match for the winter blast.
The sight of cross-country skiers cascading down monument steps and flying snowballs has since given way to images of people hunched over snow shovels or huddled next to fireplaces.
John and Nicole Ibrahim and their 2-year-old son, Joshua, have been without power at their suburban Washington home in Silver Spring, Maryland, since overnight Friday. They were among hundreds of thousands without electricity across the region, and utilities warned it could be days before electricity is restored to everyone.
"We were all bundled up in the same bed together and (Joshua) was coughing in his sleep and his heart was racing, and we worried he might be getting pneumonia," Nicole Ibrahim said.
The National Weather Service called the storm "historic" and reported a foot of snow in parts of Ohio and 2 feet or more in Washington, Delaware, New Jersey and Pennsylvania. Parts of Virginia, Maryland and West Virginia got closer to 3 feet.
Eric Berry, a plow driver for Baltimore, said he worked 12-hour shifts Saturday and Sunday. He said overanxious residents were sometimes hindering his ability to clear secondary roads by digging out their cars and moving them into the path of his plow.
"They feel like they need to park in the street, so that when it's time to go, they can up and go," Berry said.
In Philadelphia, 28.5 inches of snow fell during the storm, just shy of the record 30.7 inches during a January 1996 blizzard. Snow totals were even higher to the west in Pennsylvania.
Almost 18 inches was recorded at Washington's Reagan National Airport, which had canceled all flights. That's the fourth-highest storm total for the city, and airport officials haven't decided when flights would resume. At nearby Dulles International Airport in Virginia, the record was shattered with 32 inches. Some flights there have resumed.
At Reagan National Airport, 59-year-old Gwen Dawkins was trying to get back to Detroit. She was supposed to leave Saturday but still hadn't Sunday afternoon because of delays and cancellations. And she said there was "no way we're getting out of here tonight."
"You've got a whole city held captive here," she said. "They were very ill-prepared."
Authorities say most public transportation in Philadelphia has resumed. In Pittsburgh, bus service restarted but light-rail wasn't running. Washington's Metro trains were to be limited Monday to underground rails, and its buses were going to operate on a very limited basis.
In Mount Lebanon, a suburb south of Pittsburgh, Robb and Meredith Hartlage were again trying to clear the sidewalk in front of their house.
"We did a couple hours yesterday. I would say about four hours mixed with sledding," said Robb Hartlage, 40, who said he's not too old to play in the snow. He acknowledged, however, that the shoveling was hard work.
"I made some 'old man' noises when I got out of bed," he said.
