Air travelers hoping to spend Thanksgiving with loved ones in the northeast have endured hundreds of flight cancellations, thousands of flight delays, and over 100 accidents on snow-covered roads, reports NBC News.

The winter weather caused 748 flight cancellations Wednesday and delayed 4,794 more, with most cancelled flights affecting LaGuardia airport in New York, Newark Liberty airport in New Jersey and Philadelphia International, according to NBC News.

Albany, New York broke a single-day record on Wednesday evening when it received 6.7 inches of snow with more expected, according to the National Weather Service said. Bergen County, New Jersey, received more than 4 inches of snow. Areas of Maine accumulated 8 inches of snow. New England was predicted to have as much as a foot and a half of snow.

New Jersey Gov. Chris Christie declared a state of emergency. In neighboring Connecticut, state police reported over 100 accidents and more than 7,000 homes and businesses without electricity.

Thanksgiving drivers along the stretch of Interstate 95 from Washington, D.C., to Maine have experienced rain to the east and 7-18 inches of snow to the west.

Amtrak told NBC News it was operating and, so far, unaffected by the storm.

The Defense Department has offered to open unused military airspace along the East Coast, the Gulf of Mexico and the southwest for commercial flights through Sunday.

The good news is that the storm system passed without leaving high wind behind. New York City's Macy's Thanksgiving Day Parade floats have been able to soar high without interference from Mother Nature.

Much of the northeast has a 30 percent chance of rain showers or snow flurries Thanksgiving Day with temperatures in the high 20s to 30s, according to the National Weather Service.

The west coast is expecting heavy rain and a chance of snow through the weekend.
