Round One Snow: Philly to NYC Friday Night, Saturday

 

  

 State College, Pa. — 15 February 2013AccuWeather.com reports a swath of snow will streak northeastward across the coastal mid-Atlantic to southern New England spanning late Friday night into Saturday, ahead of a major snowstorm for coastal areas of the Northeastern states a bit later in the weekend.

The snow will not fall along I-95 in the mid-Atlantic until after the evening rush hour.

The snow will start as rain in portions of the mid-Atlantic but will end as snow.

The disturbance producing the snow is an early part of a developing storm just offshore this weekend.

While the snow from the preliminary disturbance may not last long, the snowfall rate could be close to an inch per hour in a few locations, causing road conditions to change rapidly.

A quick 1 to 3 inches of snow can result in wet and slushy travel by Saturday morning along I-95 from Philadelphia, New York City and Hartford. A slushy coating of snow is possible around Washington, D.C., with a coating to an inch farther northeast around Baltimore, Md., and Wilmington, Del.

Many secondary roads and streets in the suburbs are likely to have conditions ranging from slushy to snow covered.

Mixed rain and snow showers will transition to snow showers Friday evening over the central Appalachians, which can also bring a coating to an inch and perhaps a bit more in the snowiest spots over the ridges.

The main storm will organize quickly Saturday afternoon and evening just off the Virginia Capes.

From this point, the storm may begin to put down accumulating snow in portions of northeastern North Carolina, southeastern Virginia, the Delmarva Peninsula, the Jersey Cape and central and eastern Long Island.

It is a close call with additional snow over the coastal mid-Atlantic from the main part of the storm Saturday night from Washington, D.C., to Philadelphia and New York City. Odds favor the heaviest and perhaps all of the snow during this time staying to the east of these cities.

However, areas from eastern Long Island and Cape Cod northeastward through Maine and the Canada Maritimes are most likely to experience a significant snowstorm with conditions trending nastier farther north. Blizzard conditions are possible from Maine northward.
