A storm swinging up from the southern Appalachians will bring a commuter's nightmare to a large part of the Northeast Wednesday night into Thursday.
The fast-moving storm will bring a few hours of heavy snow following Wednesday's rainy weather.
Senior Meteorologist Kristina Pydynowski warned, "Heavy rain and poor drainage area flooding will cause their share of travel problems as well."
After 1 to 2 inches of rain falls on the region, for a short time late Wednesday into early Thursday, the snow can fall at the rate of an inch or two per hour in the central and northern Appalachians to part of New England.
Motorists should allow plenty of extra time to get around Thursday morning, even though the storm will be already showing its tail.

The I-95 commute in the mid-Atlantic and southern New England Thursday morning will be mostly wet, but slow nonetheless with the weather ranging from rain to mixed rain and snow to all snow.
Road conditions from Richmond to Washington, D.C., will be just wet. In fact, the storm will be over by the bulk of the morning rush. However, anywhere northeast of Washington, D.C., to Boston, Mass., unannounced patches of slush and slippery conditions can occur, especially on bridges and overpasses as rain ends as a period of wet snow in most places.
Roads from northern and western Connecticut and western and central Massachusetts to Maine will go from wet to slushy and even snow covered in a matter of minutes early Thursday morning. This includes I-89, I-90, I-91 and I-95.
Motorists and pedestrians should also be on the lookout for icy patches Thursday evening into Friday morning. Untreated areas that are still wet will become icy as temperatures dip fall below the 32-degree mark.
