Inclement weather extended the Christmas break for thousands of Americans.
Winter storms caused at least 1,500 flight cancellations on Wednesday and more are already being called off Thursday.
Road travel is not much better. Slick conditions have travelers hunkering down and staying put.
The powerful winter storm that's been pounding the country's heartland headed northeast Thursday. It's classified as a nor'easter, bringing with it high winds, snow, and sleet.
The massive storm system has already wreaked havoc in areas from Arkansas to Indiana, dropping record amounts of snowfall.
"We tried to get out of the parking spot over here in front of my apartment and we're spinning in circles," Indiana resident Tanya Collins said.
The storm even led to a Christmas outbreak of rare winter tornadoes. Mobile, Ala., was hit particularly hard.
"You kind of forgot it was Christmas there for a while," Mobile resident Ricky Cauly said.
"The power went out and we could hear it coming and then we ran and jumped into the bathtub," another resident said.
Forecasters are calling for 12 to 18 inches of snow from New York to Maine Thursday, with the heaviest snowfall landing in Pennsylvania, upstate New York, and some other New England states.
"If you could stay out of it, stay out of it," motorist Steve Moore advised.
The winter weather conditions are extremely hard on travelers looking to return home after the holidays.
"We're trying to get home; or plan B, we go spend more time with the grandkids here," one holiday traveler said.
"Every flight to Dayton canceled today. (We) may or may not make it," another traveler said.
Officials warn travelers to stay off the roads if possible. Heavy traffic makes it difficult for snow plows to get through.
The storm system is expected to taper off into a mix of rain and snow as it nears the coast.
