CHICAGO, Nov. 20 (UPI) -- Experts say weather-related airline delays in Chicago, New York and Philadelphia are expected to worsen and spread during Thanksgiving week.
Tom Moore, a senior meteorologist at The Weather Channel, said severe weather is expected to spread around the Rocky Mountains, the Gulf of Mexico and Vermont on Wednesday, the day before Thanksgiving and commonly one of the busiest travel days of the year, USA Today reported Tuesday.
"Wednesday is going to be a nightmare over a lot of the country," Moore said. "Although it's not going to be a colossal storm, there's going to be so much rain and low clouds, I would say there are going to be significant delays over large parts of the country."
Airlines have said the 12-day period surrounding the holiday is expected to mark a record number of passengers, with 90 percent of all airline seats filled.
Moore said Chicago is expected to experience snow Wednesday, as thunderstorms stretch from the Gulf Coast to Kentucky. Heavy storms are expected to hit New York on Thanksgiving, but the holiday is commonly one of the lightest travel days of the season.
