A second winter storm in as many days will slam parts of the Midwest before rolling toward the East Coast. Major travel disruptions are likely.

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.

A wintry mess was bearing down on mid-Atlantic states Tuesday with forecasts of significant snow and ice accumulations prompting warnings of potential power outages. Travel will become treacherous Tuesday through early Wednesday in much of Virginia and West Virginia the National Weather Service said.
