Snow has changed to rain at the New York City area’s major airports, where more than 300 flights were canceled and air travel delays of more than an hour linger.
“Within the past hour many of our terminals have gone over to rain,” said Mike Layer, a National Weather Service meteorologist in Upton, New York. “LaGuardia, Kennedy and Newark and Islip are all reporting rain.”
The storm contributing to 723 flight cancellations in the U.S. as of 1:30 p.m. Eastern time, according to FlightStats Inc., a tracking company in Portland, Oregon. Most of the scrubbed trips were at Newark Liberty International Airport on New Jersey and LaGuardia in New York, with a combined 330.
Delays of more than one hour were reported at LaGuardia, Newark, John F. Kennedy International, Philadelphia International and Reagan Washington National, according to the Federal Aviation Administration.
A winter weather advisory stretches from southern Maine to central Pennsylvania, according to the weather service.
Boston, which was just overcast as of 2:30 p.m. East Coast time, was expected to receive less than 2 inches (5 centimeters) of snow from the storm, according to the Weather Service. New York got a sprinkling before the snow changed to sleet and then rain.
After today, temperatures along the East Coast are expected to rise, shaking off last week’s cold, said Tom Kines, a meteorologist with AccuWeather Inc. in State College, Pennsylvania.
Temperatures may reach 58 degrees Fahrenheit (14 Celsius) in New York and 57 in Boston in two days, according to the Weather Service. Philadelphia’s high may reach 60 and Washington’s 62.
The warmer air later opens the possibility of some “wild temperature swings” in the next two weeks, said Matt Rogers, president of Commodity Weather Group LLC in Bethesda, Maryland.
Temperatures in the U.S. Northeast may drop 3 to 5 degrees below normal from Feb. 2 to Feb. 6 before rising once again from Feb. 7 to Feb. 11, Rogers said.
Weather patterns that would bottle up the cold along the U.S. East Coast aren’t developing, so the chance the frigid air will linger are small, he said.
