Impacts from a storm targeting millions of people in the Eastern states will range from travel disruptions and power outages caused by strong wind, wet snow and coastal flooding.
For information on snow farther north, consult "Snow New York City to Boston and New England."
Snow potential over the mid-Atlantic from the storm was diminished as the center of the storm shifted offshore. Warm air rotated in from the ocean, allowing snow and a rain/snow mix to switch over to rain. Cold air came in too late in the game for heavy snow on the Eastern Shore and southern New Jersey Wednesday night.
One to two feet of snow fell from western Virginia to part of West Virginia and western Maryland Wednesday morning. The snow brought down trees and power lines. As of 3:00 p.m. EST, Wed., Mar. 7, 2013 over 200,000 were without power.
Marginal temperatures played a role in Washington, D.C. and Richmond, Va., which prevented the snow from accumulating on major roads in the downtown areas. However, areas west received heavy, wet snow.
Too much warm air has moved in from Atlantic City, N.J. to Philadelphia, Dover, Del. and Baltimore, Md. for accumulating snow on roads.
Even where snow is melting as it falls, the combination of the snow, wind and blowing spray on the highways will make for poor visibility and hazardous conditions.
Along the coast, the storm will continue to cause strong winds, as well as water rise issues and beach erosion. For more information on this consult the story "East Storm: Wind, Beach Erosion and Coastal Flooding."
AccuWeather.com meteorologists pointed out that the storm this week may bear some similarities to the Ash Wednesday Storm of 1962. The historic storm caused everything from feet of snow to high winds and extensive coastal flooding.
Odds are against tremendous impact lingering for three or four days like the intensity of the '62 Ash Wednesday Storm. However, there will be minor to moderate coastal flooding and beach erosion occurring through the end of the week due to rough surf even as winds slowly diminish.
