US Winter Forecast: Cold, Snow to Seize Northeast; Wintry Blasts to Slick South

Though parts of the Northeast and mid-Atlantic had a gradual introduction to fall, winter will arrive without delay. Cold air and high snow amounts will define the season.

Farther south, ice storms and snow events will threaten the Tennessee Valley and parts of the southern Plains. Much of the South can prepare for a wet winter, with some severe weather encroaching on Florida.
