Detailed Summary:
Low pressure over the Northern Gulf of Mexico on Monday moves to the Southeast on Tuesday and off the East Coast by Wednesday. This system had a lot of uncertainty associated with the storm. At times the system looks like it would bring heavy snow to the parts of the Tennessee Valley into the Southern/Central Appalachians and the Mid-Atlantic, and parts of the Northeast. Now the system will move off the East Coast, and there will be a lack of cold air over the eastern third of the country. The storm will produce some snow around the periphery over parts of the Tennessee Valley and Central Appalachians, with the greatest likelihood of any heavy snow to occur at night or the highest elevations. Any areas of widespread heavy snow are unlikely at this time.
