Over 650 flights have been canceled while more than 3000 were delayed due to a winter storm that affected much of the East Coast on Thanksgiving Eve, the busiest travel day of the year.

The Nor'easter brought heavy rain and snow accumulation on Wednesday. The storm began early Wednesday morning, dumping rain on drivers in Boston, New York, Philadelphia and Washington. By noon, the rain turned into snow in every state from Virginia to Maine.

"If this was any other day of the year, it would be a pretty big storm but nothing too out of the ordinary," said Kevin Roth, a meteorologist at The Weather Channel, according to NBC News. "But it's come at one of the worst possible times, the day before Thanksgiving. It's going to be very, very tricky for anyone planning to travel today."

Due to the weather conditions, some commuters decided to play it safe by changing their travel plans.

"I don't want to risk it," said Jenna Bouffard, a New York City public relations executive who headed for her family home in Massachusetts, a day earlier than planned to ABC News. "I'd rather be safe than sorry, and if it doesn't snow, then I just have an extra day at home with my family."

West Virginia, Pennsylvania, Maryland and New Jersey were expected to receive 3 to 6 inches of snow, while interior New England as much as a foot and a half.

Fortunately, the East Coast storm is expected to clear out by Thursday.

In New York City, the snow and rain are expected to be gone by Thursday morning, just in time for the annual Thanksgiving Day Parade in Manhattan. Temperatures will be around 40 degrees, but the wind chill factor will make the temperature feel around 20 degrees.
