A near-classic Gulf system is expected to develop on Saturday along the north Gulf coast and move east northeastward across north Florida Saturday night. The system is expected to intensify and move northeastward along or just inland of the east coast on Sunday, eventually becoming a deep low early Tuesday morning over Long Island. The system should move north northeast into southeastern Maine by Tuesday afternoon.

Rain likely over Florida Saturday night and Sunday morning as the developing system heads for the Atlantic coast in southeast Georgia. The first widespread rain event in Florida in about a month - with just a small chance for a few severe storms on Sunday. I would expect the storm system to occlude along the warm front with enough cold air wrapped around the system to bring snow to all of New England and southeastern New York on Tuesday. With pressure dropping to about 980mb, I'd also expect high winds and near blizzard conditions over the Northeast late Monday into Tuesday. Unseasonably cool temperatures can be expected in the Southeast on Tuesday and Wednesday.
Cheers,
