The first storm, which could be particularly intense, is projected to take an inland track early next week, from the Gulf of Mexico toward the eastern Great Lakes. Such a track would draw up enough warm air for mostly rain along the East Coast. But interior locations in the Ohio Valley and eastern Great Lakes could see their first significant snow.
There’s some chance for a second storm to develop slightly to the east of the first one around Dec. 3 or 4, opening up the possibility for wintry precipitation closer to the East Coast.
