The same storm system that produced dangerous ice across the Midwest will set its sights on the mid-Atlantic and New England for Monday.

While areas farther west are already dealing with glazed roadways and sidewalks, residents of the mid-Atlantic are still reeling from a week of frigid temperatures.

AccuWeather.com Meteorologists are monitoring a big warm-up which will help to thaw most of the Midwest and East out from the deep freeze.

However, the warm up comes at a price in the form of ice to begin the work week.

After midnight, a mess of wintry precipitation moved into Pittsburgh, Buffalo, State College, Harrisburg, Binghamton and Scranton.

The precipitation will start as a mix of snow, sleet and freezing rain across western Pennsylvania before transitioning over to plain rain. Farther to the east, a period of snow will develop over central Pennsylvania and central New York which could accumulate an inch or two by daybreak before the precipitation changes to ice.

Farther to the south, a bit of sleet and freezing rain will develop across the Washington D.C., and Baltimore metro areas toward daybreak. This could be bad news for the morning commute as just a light amount of precipitation can lead to glazing on sidewalks, elevated surfaces and non-treated roadways.

Most of the precipitation will transition over to plain rain or drizzle in the D.C., and Baltimore regions by the afternoon hours.

School delays across the mid-Atlantic are more than likely and some schools may have to postpone classes for the day if conditions are slow to improve.

Farther to the east, a few inches of snow is likely to accumulate after daybreak across upstate New York with the snow spreading into cities such as Manchester, N.H., Boston, and Providence, R.I. by the afternoon hours.

Ice could linger much of the day over central and northeastern Pennsylvania, which could lead to significant travel problems and even some road closures.

In Philadelphia and New York City, precipitation is expected to develop by the mid-morning hours with a little snow and sleet at the onset before a changeover to rain. With a wind off the water, AccuWeather.com Meteorologist Brian Wimer expects that any freezing rain in New York City would be brief before temperatures warm above freezing.

He is, however, concerned that areas from the northern suburbs up into the Hudson Valley could experience an extended period of icing.

In Philadelphia, the precipitation should transition to rain by afternoon, but not before a glaze of ice creates messy travel conditions during the morning commute.

AccuWeather.com Meteorologists will continue to monitor the impending winter storm across the high population zones of the mid-Atlantic and New England.
