Snowstorm to snarl travel from DC to New York City and Boston Thursday

A quick change to colder weather will be accompanied by accumulating snow from the mid-Atlantic to eastern New England into Thursday night.

The cold and snow follows on the heels of record warmth across the Northeast on Wednesday.

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

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

Major travel delays and disruptions to daily activities are likely from accumulations ranging from a slushy coating to as much as 12 inches.

Airline delays will increase exponentially, due to aircraft deicing operations and slippery runways. Flight cancellations will continue to mount.
