AccuWeather: Rain, Ice, Snow Expected to Impact Southern Tier

Forecasters are calling it a double-barreled storm that will first spread rain, ice and snow into the northeastern United States during Saturday and Sunday. However, it is the tail end of the storm that may bring a foot of snow to part of the region from Sunday night to Monday.

A storm system from the Midwest is forecast to crawl into the region spanning Saturday, Saturday night and Sunday. The storm will initially fight with dry air; however, the same dry air and cold ground at the onset will also set the stage for slippery conditions in many locations.

While hammering much of the North Central states at the same time, rain and a narrow zone of ice will develop over the central Appalachians later Saturday.

As the storm advances and moisture increases, the swath of ice will expand over the eastern Great Lakes, Appalachians and interior mid-Atlantic during Saturday night to Sunday morning.

This means that motorists venturing along the Interstate 70, 76, 79, 80, 81, 86, 90 and 99 corridors may encounter slippery conditions.

Roads that appear wet may be icy, especially but not limited to bridges, overpasses and areas that are sheltered from direct sunlight.

Rain will expand to the lower mid-Atlantic coast during Saturday afternoon and night, including the Baltimore, Philadelphia, Washington, D.C., and Richmond, Virginia, areas.

During Sunday, a second storm center is forecast to develop along the mid-Atlantic coast. Eventually, this coastal storm will take center stage.

The rain will reach northward along the Delaware and New Jersey coasts. However, around the New York City area and the southern New England coast, conditions in the atmosphere may be such to allow a mixture of rain and sleet to occur at the onset.

The area of ice is forecast to broaden over the Northeast as cold air holds its ground and the atmosphere begins to moisten up.

Meanwhile, on Sunday, atmospheric conditions will allow mainly snow to spread across northern and eastern New York state to western and central New England.

It is during Sunday night to Monday, when the effects of the strengthening coastal storm are likely to be realized.

Difficult and dangerous travel is likely to develop from Sunday to Sunday night along much of the New York Thruway, as well as the Massachusetts Turnpike and portions of I-84, 88, 89, 91, 93 and 95. Conditions along these highways will range from wet to slushy to snow-covered.
