A dangerous winter storm brought significant snowfall, strong thunderstorms and blustery winds to the northeastern U.S. on a holiday Monday. The storm system dropped a foot (30 centimeters) or more of snow in parts of New York state, Ohio and Pennsylvania Sunday night through Monday morning after pummeling parts of the Southeast on Sunday.

“We’ve had a very strong area of low pressure that’s kind of moved up the coast, with pretty heavy snowfall accumulations from Tennessee, North Carolina all the way into the northeast,” said meteorologist Marc Chenard at the weather service’s headquarters in College Park, Maryland.
