As showers and storms move across Central Florida on Christmas Eve, the lines at Orlando International Airport's security checkpoints moved at a mostly steady pace Wednesday, but on the big board, many flight delays were shown out of the Northeastern U.S.

Only a handful of departures from Orlando were delayed Wednesday, but dozens of arrivals coming in from all over the country, from Chicago to Atlanta, were not on time.

While it may not be the weather in Orlando that causes delays in the skies, snow in the northern states, as well as other harsh storms, could pose more problems for travelers.

"I'm flying to Baltimore, Maryland, and I'm a little bit nervous, because I'm supposed to work tonight," said Charlene Adolphe, waiting for her flight out of Orlando. "I heard there were some storms in the area, so I'm hoping for no delays."

"We're flying to Washington, D.C.," said Pat Harlow. "We're going home for the holidays, and we expect the weather to be very rainy, but no delays at this point. We're keeping our fingers crossed."

For those traveling to colder climates, snow threatened the Great Lakes, and interstate highways from Colorado to Kansas were shut down Wednesday due to high winds and snow.

The potential for tornadoes from severe thunderstorms in the Gulf States threatened Mississippi, Georgia and Louisiana.

The mid-Atlantic and New England states saw rain Wednesday, and flight delays began early in Philadelphia.

Along with anxious travelers hoping their flights out of Orlando were on time, many were left waiting for their loved ones to arrive.

"We're standing here, anxiously awaiting our daughter, son-in-law and stepdaughter to get off the plane from Nashville, Tennessee," said Sandy Usher. "The board says that she's on time, so she should get off the board at any time. So, we're kind of anxious right now."

Other families had some fun while they waited at the airport, including Christine Thomas and her family, from Ottawa, Canada.

"In our family, we started everybody having onesies for Christmas, so now my brother's arriving from Rochester, New York," explained Thomas, adorned in plaid, red holiday pajamas. "We're trying to get here, and he's going to be really surprised."

But not everyone had smooth sailing, including Stephanie Bamberger, who was heading home to Baltimore.

"We don't know why, but this morning they delayed us," said Bamberger. "It was a 4:05 flight, and now I think 5:40 or 5:45, we're supposed to take off."

AAA predicted a peak in holiday travelers this year, the highest recorded since 2001.
