Oncoming Storms Expected to Cause Travel Delays Before Thanksgiving

The U.S. seems poised for a rough Thanksgiving with severe weather across a range of regions: According to CNN, an Arctic air mass will probably keep temperatures 15 to 20 degrees below normal along the East Coast through Thursday. But even without snow, forecasters are expecting fierce winds that could make air travel difficult.

The central and western parts of the country have already seen rough weather that caused significant travel delays: Airlines flying in and out of Dallas/Fort Worth International Airport "pre-canceled about 300 departures to reduce the number of stranded travelers" Sunday in anticipation of the harsh weather, the airport's official Twitter account said. And 10 percent of flights at Oklahoma City's Will Rogers World Airport were also canceled because of the weather Sunday. New Mexico, meanwhile, could see up to eight inches of snow accumulating through Monday.

According to NBC, the mountains of Utah and Colorado have already seen a foot of snow, and 13 people have been killed in weather-related incidents, including a 4-year-old girl who was killed in a rollover crash on an icy road in New Mexico.

For the upcoming holiday, NBC expects 43 million travelers with 3.1 million expected to fly. Air travel could be delayed in New York, Boston, Washington and Baltimore. The storm is expected to leave up to a foot of snow across the Buffalo and Syracuse, N.Y., areas, and up to eight inches in Pittsburgh. The Weather Channel is predicting a thin band of sleet and freezing rain north and west of Interstate 95 from Maine to northwest Virginia.

But there is hope: Wednesday night, virtually all precipitation will have ended, with the exception of wrap-around snow over northern New England, Upstate new York, and some lingering lake-effect snow. And CNN expects that the worst weather will be over by Thanksgiving Day, though much of the Northeast will still get a layer of snow Thursday.
