Snowstorm to Snarl Travel from Washington D.C. to New York City and Boston On Thursday

A quick change to colder weather will be accompanied by accumulating snow from the central Appalachians to New England spanning Wednesday night into Thursday.

Just hours after record-challenging warmth occurs, temperatures will plunge 15 to 30 degrees Fahrenheit from the Midwest to the interior South and northeastern United States during Wednesday night and into Thursday morning.

The storm will begin with a brief period of rain in some areas, but will quickly change over to snow as temperatures plummet. Initially the snow will melt on paved surfaces. However, that can change in a matter of minutes as the rate of snow picks up.

Despite the warmth into midweek, snow will fall at a fast enough pace to lead to slippery roads and airline delays as the storm progresses.

“The wet, clinging nature of the snow will weigh down tree limbs and could lead to sporadic power outages,” according to AccuWeather Senior Meteorologist Henry Margusity.

Major cities at greatest risk for a period of accumulating snow include Pittsburgh, Philadelphia, New York City and Boston.

The storm will affect heavily-traveled stretches of Interstate 68, I-70, I-76, I-78, I-80, I-81, I-83, I-84 and I-95.

“Cold air will come in fast enough and the storm will strengthen enough to produce a swath of heavy, wet and accumulating snow from the mountains of northern Virginia and West Virginia to much of New England,” according to AccuWeather Meteorologist Mike Doll.

Major travel delays and disruptions to daily activities are likely from accumulations ranging from a slushy coating to as much as 12 inches. The snow could fall at the rate of 1 to 2 inches per hour. Thunder and lightning can accompany the snow in some locations.
