More wintry weather is headed for the northeast, but unlike the last system, mild air is expected to surge far north and inland bringing rain to many areas that have only seen snow this week.
With this morning’s quick moving storm that affected the Mid-Atlantic already on its way out to sea, the core of an upper-level trough is going to swing through the eastern half of the ontinental United States today setting the stage for the next round of precipitation Thursday into Friday in the northeast.
Moderate to heavy snows have already been falling across the Central Missouri Valley into the Upper Mississippi Valley into the Central Great Lakes.
A surface low is likely to develop and enhance higher moisture and unstable air back across the Lower Mississippi Valley and across Mississippi and Alabama today. Severe weather is likely to occur from southern Louisiana to western Virginia where there is a potential for large hail, severe winds, tornadoes including possible strong tornadoes. Along with the strong storms, multiple rounds may occur with heavy rainfall. The severe/flash flooding risk will remain for Thursday across Georgia into South Carolina and northern Florida too.

Moderate to heavy rainfall moving across the Cumberland Plateau may intersect with recent snowfall, increasing the risk of stream/river flooding as rain and melt combine quickly as runoff.
The areas that saw heavy snow across the Mid Atlantic will see simply plain rain tomorrow, although plain rain may start as freezing rain or sleet over the highest terrain of West Virginia, western Maryland and Virginia, and southwestern Pennsylvania.
Across northern New Jersey, northeastern Pennsylvania, and southern Upstate New York, precipitation will start as light snow early but change to plain rain there, with soaking rains likely to spread into much of southern New England and even coastal Maine.
As colder air wraps around behind the storm, some rain will briefly change back to snow, with accumulating snow possible from this wrap-around part of the storm across portions of western Pennsylvania and New York state.
