Flight-Grounding Snow Ends in New York and Washington

Dec. 10 (Bloomberg) -- Snow is ending in New York after a quick-moving storm caused hundreds of flights to be canceled around the Northeast, left travelers delayed for hours and shut down government offices in Washington.

About 2.5 inches (6.4 centimeters) fell in the Bronx and 1.4 inches in Central Park, according to the National Weather Service in Upton, New York.

“New York City has just about seen the last of it,” said Gary Best, a meteorologist with Hometown Forecast Services Inc. in Nashua, New Hampshire. “They may see some snow showers during the evening commute.”

The storm, which triggered warnings and advisories from Tennessee to Massachusetts, contributed to 1,363 U.S. flight cancellations, according to FlightAware, a Houston-based airline tracking service.

Delays of more than an hour were reported at the New York area’s three major airports and in Philadelphia at 2 p.m. East Coast time, according to the Federal Aviation Administration website. Earlier in the day, Newark Liberty International Airport reported delays exceeding five hours.

“Anytime we have any kind of storm up this way, and visibility goes down, they have to space the airplanes out more than normal,” said Adrienne Leptich, a weather service meteorologist in Upton, New York. “You have backlogs.”

In addition to the delays, 280 flights through Newark were canceled, as well as 211 at LaGuardia and 253 in Philadelphia, according to FlightAware.

Freezing Weather

Temperatures along the U.S. East Coast will fall below freezing tonight and turn standing water to ice, Best said. Tonight’s low in New York will be 22, according to the weather service, which forecast sunny skies from Washington to Boston tomorrow.

Much of the eastern U.S. from the Great Lakes south to Texas and up into the Northeast will be about 8 degrees or more below normal until Dec. 14, said Matt Rogers, president of the Commodity Weather Group LLC in Bethesda, Maryland.

Temperatures across Canada will be from 8 to 15 degrees below normal.

Below-normal temperatures, especially in eastern and Midwestern cities, tend to increase energy consumption as more people heat homes and businesses. Gas is used to heat about 49 percent of U.S. households.

The normal average temperature in New York on Dec. 11 is about 40 degrees, according to MDA Weather Services in Gaithersburg, Maryland. In Boston, it’s 37; in St. Louis, 36; Dallas, 48; Houston, 55; Chicago, 29; Burbank, California, 54; and in Calgary, it’s 21.

Best said there is a chance for another round of light snow this weekend from New York to Boston. He said snow may start in New York on Dec. 14 before changing to rain.

In Boston, it could be mainly snow.
