Tens of millions of residents along the East Coast are bracing for several inches of snow Sunday followed by dangerously cold temperatures that will take hold in much of the country from the Northern Plains to the tip of Maine.

The National Weather Service issued a winter storm warning at 9:21 a.m. on Sunday in effect until Monday at 9 a.m. for Westmoreland Ridges and Fayette Ridges.

The widespread winter storm will most likely bring steady snow to the area by early afternoon. The snow will continue until just before 9 p.m. and then taper off through midnight, said meteorologist Joe DeSilva of the weather service’s office in Mount Holly, New Jersey. A winter storm warning is in effect until 1 a.m. Monday.
