Accuweather offers report on impending blizzard

Accuweather has issued the following update…

State College, Pa. — 7 February 2013 — AccuWeather reports New York City and the northern mid-Atlantic are on the edge of a major storm that will hit New England as a blizzard Friday and Friday night.

The storm will bring at least a few inches of snow and a period of high winds from central New Jersey to the lower Hudson Valley.

Even though the area from central New Jersey to southeastern New York state will not be in the epicenter of this storm, enough snow will fall to cause travel problems and winds can be strong enough for a time to cause downed tree limbs and sporadic power outages.

Only if two storms, an Alberta Clipper from the west and a storm from the South, merge very quickly will there be more than a manageable amount of snow in New York City, northern New Jersey, southwestern Connecticut, Long Island, northeastern Pennsylvania and upstate New York.

According to Winter Weather Expert Rob Miller, “While this is a possibility, it would be difficult for a storm to do this without a blocking area of high pressure to the northeast.”

Such an area of high pressure would slow the forward speed of the storm down long enough to cause it to strengthen into an intense area of low pressure.

Warm air will be the issue in the New York City metropolitan area and Long Island causing part of the storm to be rain or a wintry mix.

Odds favor wet roads around the New York City to a few slippery spots north and west for morning rush hour Friday. However, as more snow starts to mix in later in the day and a change to all snow likely by Friday evening, road conditions could rapidly deteriorate for the drive home Friday.

Low cloud ceilings and increasing winds during Friday may lead to building flight delays and cancellations even if snow were to stay away from the several major airports in the New York City area.

Farther south, the warm air may bring all or mostly rain to Philadelphia, Baltimore, Washington, D.C., southern New Jersey, the Delmarva Peninsula, much of the Maryland mainland and much of Virginia.

Depending on the speed of the merger of the two storms, a few inches of snow could fall on parts of southeastern Pennsylvania and southern New Jersey. Regardless of how quickly the two storms come together, at least several inches of snow will fall over northeastern Pennsylvania, northern New Jersey and southeastern New York state.
