It's going to be a fast introduction to winter this weekend, as the East Coast and even the South see a snowstorm that will span 2,000 miles in total. Plan on hard travel conditions, the weather service says.
The snow will intensify in the Northeast by mid-Saturday morning and stay in the region until nightfall, and in New England throughout Saturday night.
Lake Charles to Baton Rouge, Louisiana, is under a winter weather advisory, while Jackson, Mississippi, is under a winter weather warning.

Farther south into Maryland, the accumulation grew, where Salisbury, Fruitland and Delmar all saw at least 7 inches of snow. Three to six inches is anticipated throughout much of the area, with the highest accumulations possible in the northwest and lower amounts in the Cape and islands.

Washington, D.C., can expect one to three inches, while the rest of the Northeast, from eastern Pennsylvania, central to northern New Jersey, and NY to ME will likely see three to five inches this weekend.
