Snowstorm to blanket DC to New York City, Boston; Roads to turn slushy, snow-covered

A storm with snow will make for slushy and snow-covered roads in much of New England and in coastal areas of the mid-Atlantic during the first part of this weekend.

The storm will take a northward turn and track close enough to the Atlantic coast to throw moisture in the form of snow over the Interstate 95 corridor. This is the same storm that has been producing snow from Texas to North Carolina into Friday.

Snow will ramp up over parts of Virginia on Friday, before spreading farther north over the mid-Atlantic during Friday night. The storm will affect the upper part of the mid-Atlantic Saturday into Saturday night.

Where more than an inch or two of snow falls, roads will transition from wet to slushy to snow-covered. Slippery spots are likely even where a small amount of snow falls.

However, the first areas to become slippery will be elevated surfaces such as bridges and overpasses.

2017 winter weather predictions

This year's Farmer's Almanac predicts less precipitation in the Pacific Northwest and Upper Midwest, but other areas might not be so lucky ...

The National Oceanic and Atmospheric Administration predicted La Nina will potentially emerge this winter season, bringing with it above-average precipitation and below-average cold temperatures.

But if La Nina does hit, it will impact each U.S. area in a different way ...

For example, the Rockies would likely be rocked with abundant snowfall, while the Midwest would be plagued with blasts of cold air.

Another more wonky model from Atmospheric and Environmental Research predicts that colder temperatures could hit the East Coast if there is a stratospheric polar vortex disruption.

Changes in the jet stream have a direct impact on weather patterns, and in the earliest days of December Americans could see a cold front and snow in the Plains and upper Great Lakes.

Averaging 44 inches of snow each winter, Boston is known to get slammed with tough weather. This year, NOAA predicts the historic city will see within 10 inches of that average.

The storm has had a history of producing such conditions as far south as Houston on Friday morning.

"Where it snows at a decent rate, it can accumulate on roads this time of the year, including in the major cities," according to AccuWeather Senior Snow Warning Meteorologist Brian Wimer.

As the storm progresses, slushy conditions will develop even in the urban areas along the I-95 corridor.

The snow will also cling to trees. Since some of the trees are holding onto leaves, some tree limbs may bend or break and cause sporadic power outages.

Since the storm is not terribly strong, winds are not likely to kick up enough to lead to widespread power outages.

Airline passengers should expect delays due to deicing, poor visibility and a low cloud ceiling. Some flight cancellations may occur if runways become slippery.

Up to a few inches of snow is likely to fall on the major cities from Roanoke and Richmond, Virginia, to Washington, D.C., Baltimore, Philadelphia and New York City early on during the storm.

Boston and Worcester, Massachusetts; Providence, Rhode Island; Hartford and Bridgeport, Connecticut; Concord and Portsmouth, New Hampshire; and Portland, Bangor and Houlton, Maine, are likely to be on the receiving end of several inches of snow.

"While a 3- to 6-inch snowfall is most likely in New England, that sort of snowfall may extend all the way down to parts of New Jersey, Delaware, southern Maryland and central and southeastern Virginia," according to AccuWeather Senior Meteorologist Bernie Rayno.

"Temperatures will be a little lower in New England, when compared to Virginia, but there may be just as much moisture available on a straight line from eastern Maine to southeastern Virginia," Rayno said.

Little snow is likely to fall from the Adirondacks and Catskills in New York state to the Poconos in Pennsylvania and Allegheny Mountains in West Virginia.

Rain and/or a wintry mix will cut down on accumulations in southeastern Virginia, the lower part of the Delmarva Peninsula, eastern Long Island, southern Rhode Island and southeastern Massachusetts.

A second storm will swing in from the west later this weekend.

This clipper storm will have much less moisture to work with but can bring accumulating snow showers to some areas that escaped snow from the coastal storm.

The clipper storm is likely to bring a small amount of snow to northern and western New York to northern and western Pennsylvania to western Maryland and West Virginia.
