As a nor’easter eyes the eastern United States, the National Weather Service is warning of a “potentially paralyzing winter storm” at the end of the week for parts of the mid-Atlantic region, including the Baltimore and Washington metropolitan areas, where a blizzard watch has been issued.

Three likely scenarios:

— The NWS Weather Prediction Center says the most likely track brings the heaviest snowfall to eastern Kentucky, West Virginia, western Virginia, northern Maryland and southeast Pennsylvania, with 1 to 2 feet of snow. Significant icing is likely in parts of Kentucky, North Carolina and southern Virginia with possible ice accumulations around a half inch. New York and southern New England may see snow but the amount could vary greatly, even over small distances. Coastal flooding is possible during high tide along Long Island, New Jersey, the Delmarva peninsula and western shore of the Chesapeake Bay on Friday night and Saturday.

— If the storm moves more slowly and shifts to the south, areas such as New York City could be spared the heaviest snowfall totals.

— If the storm stays further west, there could be more sleet and maybe even rain in the Delmarva peninsula and southern New Jersey.
