Seriously, tho, there clearly are no ski hills in the mid-Atlantic here as big as in New England, so to answer your question, we have to know your threshold for acceptability.
For starters, take a look at
www.skiwhitetail.com and see what you think. Its about 1000 vert. foot and is one of the closest / largest ski areas near the Balto/DC area.
The other two close ones are Ski Liberty and Ski Roundtop, but both are smaller than Whitetail. Snowshoe and Timberline in WVA are (I guess) officially in the mid-Atlantic as well, but by the time you get to them, a lot of people feel that one might as well drive north the same number of hours and get to more dependable snow at places like Elk in PA or Greek Peak in NYS (about 4 and 5 hrs, respectively, door to door from BAlto in good weather). If you are heading north from here, my personal opinion is to kiss off all of the Pocono and other resorts near NYC (especially Hunter).
Just my $0.02,

Physics man is correct about Hunter. Skip it and head for VT if you have the time. This past week, Stowe mainly got snow rather than rain. It, along with Jay Peak, probably gets the coldest weather in the NE. When it rains everywhere else, chances are good that Mount Mansfield will have snow. Also, Stowe gets incredible lake effect snow from Champlain.
