Winter Storm Watch: How much is it going to snow in DC, Virginia, Maryland?

The National Weather Service has expanded a Winter Storm Watch to cover the Washington, D.C., metro area as forecasters monitor a coastal storm that could bring accumulating snow to parts of the Mid-Atlantic late Sunday into Monday. Officials from the National Weather Service in Baltimore-Washington say the Winter Storm Watch — originally for other portions of the region — has now been expanded to include the DC metro area, reflecting increasing confidence that snow is possible this weekend.
