A period of light snow, rain and wintry mix will streak eastward into the mid-Atlantic today.

A weak storm moving into the East will bring a coating of snow to some communities from Pittsburgh to New York City. Roads will become icy tonight as temperatures plunge.

Ohio Valley States

The storm will progress across the Ohio Valley states from west to east this morning with spotty light snow across the north, rain showers across the south and an intermittent wintry mix in the middle.

Accumulations from the event will generally be a coating of snow to barely enough to wet the ground.

The best chance at a coating to an inch of snow will be along and just north of I-70 over Indiana and Ohio.

With temperatures dipping below freezing in most areas this morning, there can be icy spots around St. Louis, Peoria, Indianapolis, Louisville, Cincinnati, Dayton and Columbus for the morning drive.

Conditions will quickly improve as precipitation ends during the morning hours.

Mid-Atlantic

The storm will continue its eastward push today, moving into the mid-Atlantic.

Snow will begin to fall around the Pittsburgh area, including across parts of eastern Ohio, western Pennsylvania and West Virginia during the morning hours.

The central Appalachians may squeeze more moisture out of the storm, perhaps bringing 1 to 3 inches of snow in the mountains of West Virginia, western Maryland and southwestern Pennsylvania.

A spotty wintry mix of rain and snow will move over the I-95 swath from Washington, D.C., to Philadelphia and New York City during the afternoon and evening hours.

Most of the precipitation will fall as rain south of the Mason-Dixon Line; however, a few snowflakes can mix in at times towards the end of the afternoon with some areas turning completely over to snow during the evening.

Following snow in the evening, temperatures will drop. Roads will become icy in Philadelphia and New York City, as well as the Baltimore and the Washington, D.C., metro areas and especially in the northwestern suburbs of these cities.

A spotty wintry mix could brush the South Coast of New England Wednesday evening before heading out to sea.

There is a chance of flurries or a period of accumulating snow in part of New England and the mid-Atlantic this weekend as colder air sweeps in.
