Low pressure over the Midwest will intensify as it moves over the Great Lakes then into southeastern Canada through late-week, bringing a round of heavy rain to much of the Eastern Seaboard while snow affects parts of the Midwest and Northeast.

This Wednesday, a line of heavy rain will continue to slowly move east across the Gulf Coast states while a lighter, less steady rain impacts areas to the north, including the Ohio River Valley and interior Northeast. Meanwhile to the north and west, freezing air will be funneling into the cold sector of this storm, therefore leading to snow across portions of the Midwest and into northern parts of the Great Lakes. There will even be an area of light snow and wintry mix that will develop late in the day across northern New England as that rain moves into the cold air.

Tonight, the rain and even some thunderstorms will reach the East Coast. Therefore, a moderate to heavy line of rain is forecast from Maine all the way through central Florida during this point in time. Some localized flooding will be possible in the Northeast due to the snow on the ground. Speaking of snow, the rain will actually changeover to snow Wednesday night across the Ohio River Valley and into the eastern Great Lakes. This snow will be thumping, coming down at a pretty heavy rate. Rates may exceed 1 inch per hour at times.

By Thursday, the cold front ushering in a new round of cooler and drier air will continue to move to the south and east, allowing for the precipitation to clear out just in time for the weekend for many. Before then, however, rain will still be in the forecast across most of the East Coast Thursday morning. It will then clear out of most of the Southeast and Mid-Atlantic by midday but will stick around New England until Friday night. In South Florida, this cold front will begin to stall as it tries to clear through. Therefore, rounds of additional rain will be possible at times through early-next week. There will still be the snow component associated with this storm on Thursday as the rain switches over to snow across the central Appalachian Mountains, the northern Mid-Atlantic, and much of New England (away from the coast). A quick few inches is expected to fall before ending by Thursday night.

By Friday, the East Coast will be dry for almost everyone, and really the entire nation should be dry and storm-free overall. Due to the new round of cold air moving over the Great Lakes, however, some lake effect snow can be expected beginning Friday and continuing into the weekend.
