A winter storm that brought snow, sleet and freezing rain to a large swath of the Midwest swept into the mid-Atlantic and Northeast on Thursday, causing treacherous travel conditions, prompting school delays and closures and potential power outages for millions of Americans.

Just as one winter storm that brought snow and ice exits the Northeast, a new winter storm is expected to slam similar areas over the weekend.

The National Weather Service says another winter storm will hit the mid-Hudson Valley Saturday night and early Sunday morning.
