Snowstorm to Disrupt Travel in Midwest, Northeast

Part of a cross-country storm will affect the Midwest Sunday night then the interior Northeast during Monday with a swath of snow and rain, followed by a freeze-up in some areas.
A storm that affected the Northwest late this week and will affect the Rockies and Plains this weekend will be re-energized as it reaches the eastern third of the nation and grabs Gulf of Mexico and Atlantic moisture.
The storm will deposit snow or a wintry mix in the Tennessee and Ohio valleys Sunday night, including in the cities of Memphis and Nashville, as well as Lexington, Kentucky.

The storm will swing northeastward moving into the central Appalachians, the mid-Atlantic and New England by Monday.
Enough snow could fall on part of the I-40, I-64, I-79, I-80, I-81, I-87 and I-90 corridors to make roads slippery during all or part of the storm.

According to AccuWeather Chief Meteorologist Elliot Abrams, "As cold as it is now in the Interstate-95 swath from Washington, D.C., to New York City and Boston, it will warm up and rain with the storm on Monday."
In portions of the central and northern Appalachians, the details are complex with some areas receiving snow on the front end and tail end of the storm.

The change to rain will not reach all of the Appalachians. It is possible that the storm is all snow in the swath from Cincinnati to Pittsburgh, Syracuse, New York, and Burlington, Vermont.
On the northwest flank of the storm, a narrow band of moderate snow is possible with snow totals on the order of 3-6 inches.

Fast movement of the storm will limit the duration of the precipitation, including snow, so that snowfall over 6 inches is unlikely to occur over a broad area.
Many locations that have all snow or part-snow, part-rain should receive a couple of inches or less.
While there is a chance the rain ends as a period of snow in the I-95 Northeast corridor, from Washington, D.C., to Philadelphia, New York City and Boston, the rain is more likely to end before the cold air sweeps in.
"It will be a race between cold air and dry air in the I-95 Northeast near the end of the storm, but most often in a storm tracking in this manner, dry air usually wins out with rain ending, followed by clearing," Abrams said.
The storm will ride a new wave of cold air forecast to sweep across the Central and Eastern states.
The coldest air of the season so far will move in following the storm in the Midwest and East. Temperatures that can trump the cold conditions experienced this past week.
People from the Midwest to northern New England should not waste time clearing off the snow or removing standing water. Wet and slushy areas will freeze in the wake of the storm.

During the first part of the coming week, actual nighttime and early morning temperatures will plunge below zero in parts of the Upper Midwest and into the teens in the Ohio and Tennessee valleys.
By Tuesday, AccuWeather RealFeel® temperatures will be in the single digits and teens during much of the daylight hours from the Great Lakes region to the interior Northeast and in the 20s farther south over the Midwest and along much of the Atlantic Seaboard from the Carolinas to southern New England.
Bands of heavy lake-effect snow will continue over the Upper Midwest and will resume in the wake of the storm over the lower Great Lakes and central Appalachians Monday night and Tuesday. Given the magnitude of the cold air moving in next week, there is the potential for some areas to receive between 1 and 3 feet of snow from lake-effect.
