A storm will bring snow and ice that will lead to slippery travel along a 1,500-mile swath from northern Arkansas and Georgia to Maine early next week.
The wintry weather could be significant enough to disrupt daily activities from the interior South to interior New England.
The storm will begin in parts of the middle Mississippi and Ohio valleys, southern Appalachians and Piedmont areas of the South during Sunday night. Next, wintry precipitation will spread northeastward through the central Appalachians and mid-Atlantic on Monday and finally into New England during Monday night.
While the amount of snow and ice is not certain at this time, there is the potential for enough snow to shovel and plow in the Appalachians. Closer to the coast and west of the Appalachians, a small amount of snow and ice could lead to very slow travel on the roads and numerous flight delays.
According to AccuWeather Senior Meteorologist Paul Walker, "Enough cold air could remain wedged in parts of the interior South not only to make roads slippery, but also to cause a buildup of snow and ice on trees and power lines with the potential for power outages from parts of Georgia to Virginia and Maryland."
How quickly the wedge of cold air breaks down east of the Appalachians will determine the amount of snow and ice versus rain in the Interstate 95 to I-81 corridors.
The storm will be riding along a surge of warmer air that will bring mostly rain along the immediate Atlantic coast. However, from an area near I-95 westward to portions of I-65 and I-79, a period of snow or a combination of snow and ice is likely.
The storm is likely to make roads slippery in Nashville, Tennessee; Atlanta; Charlotte and Raleigh, North Carolina; Roanoke and Richmond, Virginia; Washington, D.C.; Louisville, Kentucky; Charleston, West Virginia; Cincinnati; Baltimore; Pittsburgh and Philadelphia; Albany, New York; Worcester, Massachusetts; Augusta, Maine.
Rapidly rising temperatures right along the Atlantic coast will bring rain or a quick change to rain. There can be a few hours of mixed precipitation, including in the swath from New York City and Hartford, Connecticut, to Boston and Portland, Maine.
In the wake of the storm at midweek, milder air from the Pacific Ocean will settle into the Ohio Valley, South and part of the mid-Atlantic, while a batch of chilly air slices into the Northeast.
