More heavy snow is set to cause problems for post-Thanksgiving travelers and commuters on the first day of December, with a new winter storm system set to hit the mid-Atlantic and New England.

The National Weather Service said early Monday that many areas could expect a wintry mix, including thunderstorms, through Tuesday. More than 6 inches of snow is possible north and west of Interstate 95, and icy conditions are expected across the central and southern Appalachians, leading to treacherous road conditions.

Winter alerts are in place from Pennsylvania to Maine, with up yo 9 inches of snow expected in some areas.

Many motorists and air travelers in the Midwest suffered over the holiday weekend, with large road crashes and hundreds of flights canceled and thousands delayed. That weather system is moving north toward Canada but could still bring snow.
