While much of the mid-Atlantic was digging out from a winter storm that brought heavy snow to the Washington, D.C., area, a second storm is expected to follow, bringing snow, sleet and freezing rain along a more northerly track from Colorado to Maine.

The primary concerns from the next storm will be icy conditions, especially in northwestern New Jersey. Hundreds of school districts delayed openings or are closed on Wednesday. More school schedule changes could be announced for Thursday morning with the next shot of winter weather.
