Nov. 23 (Bloomberg) -- Heavy rains across the U.S. Northeast will probably end by midday, easing the threat of airline backups during one of the busiest periods of the year, forecasters said.
More than 2 inches (5 centimeters) of rain may fall in New York City before the showers taper off around 1 p.m., according to the National Weather Service in Upton, New York. As much as 10 inches of snow may fall on the northern New England states of Vermont, Maine and New Hampshire.
“It doesn’t look like a good travel day for some folks,” said Rob Carolan, a meteorologist with Hometown Forecast Services. “It is going to have a big impact” early and then “will ease off in the afternoon.”
Flight delays were reported at New York’s LaGuardia Airport, Newark Liberty in New Jersey and Philadelphia International, according to an e-mailed alert from LaGuardia and the Federal Aviation Administration’s website.
About 23.2 million people are expected to fly during the 12-day period surrounding tomorrow’s U.S. Thanksgiving holiday, a 2 percent drop from last year, according to the Air Transportation Association of America, a Washington-based airline advocacy group. From 1.3 million to 2.3 million people will fly each day, with travel peaking on Nov. 27 and 28.
The storm soaked the Ohio Valley yesterday. Flash-flood watches have been posted until later today for parts of New Jersey and eastern Pennsylvania, including Philadelphia, according to the weather service. A winter storm warning and advisory stretches from northern New York to Maine.
“We’re going to see a lot of heavy rain coming through the Northeast,” said Dave Samuel, a senior meteorologist at AccuWeather Inc. in State College, Pennsylvania. “Ninety-nine percent of the people won’t be dealing with snow.”
Behind the storm, conditions are good for much of the U.S., the forecasters said.
“Thanksgiving looks perfect in the East,” Samuel said. “The storm is long gone and there will be lots of sunshine.”
Temperatures are expected to be mild, melting the snow in northern New England, said Carolan.
“It will disappear fairly quickly,” Carolan said by telephone. “Parts of New England could be up to 60 degrees by this weekend.”
The high temperature in New York City is expected to be 51 tomorrow and 60 by this weekend, according to the weather service. In Boston, it will be 48 tomorrow and 61 this weekend; in Philadelphia, it will be 55 tomorrow and 63 by the weekend; and in Washington, the high will be 57 tomorrow and 63 this weekend.
