State College, Pa. — AccuWeather.com — A major winter storm with widespread snow and ice is in the process of overspreading the Northeast, and if what has already happened farther west is any indication, this may be one of the more potent systems this winter season.

Tuesday evening through Wednesday, a large area from Indiana to New England will pick up several inches of snow, with more significant accumulations possible, significant in the sense of a foot or more. The heaviest snow from the storm will stretch from northeastern Pennsylvania into northern New England. Portions of the mid-Atlantic will have their heaviest snow of the winter so far.

The storm will also produce a major ice event from the Ohio Valley into the mid-Atlantic region. The buildup of ice will no doubt bring down trees and power lines. In some areas of the Midwest and the central Appalachians, it could very well be a crippling ice storm.
