The National Weather Service has issued winter storm warnings about serious weather conditions that are expected to affect eight American states today in ways that they described as "dangerous."

A dangerous winter storm swept across the country on Saturday, bringing rough conditions on the roads and even caused ground stops at all three major airports in the New York City metro area.

Saturday’s storm will begin moving east, allowing rain to develop in Boston and south during the afternoon, where it will be too mild for any snow to stick.
