Around 55 million people are under winter weather alerts across the northern Plains, Great Lakes, Northeast and Southeast from two separate systems.

Storms will bring some plowable snow to Massachusetts on Sunday, potentially affecting the Patriots' playoff game.

Snow began early Sunday and could last the remainder of the day. Once that clears, it’s a bitter cold week ahead.

Winter weather advisories were expanded overnight to 17 New Jersey counties with slightly higher snowfall totals now expected.

Snow was observed as far South as Florida as temperatures plummeted. New York City could get up to four inches of snow and up to six inches is possible in Boston.

As cold air continues to surge out of central Canada, more clipper storms will roll from the Midwest to the Northeast with rounds of snow, lake-effect and gusty winds into the middle of the new week.

Snow continued falling across City on Sunday, with up to 5 inches possible by the end of the day. Snow was expected to fall in two major batches, first an inch or 2 in the morning, then 2 to 4 more inches in the afternoon and evening,
