CBS affiliate WJZ  is saying the Thanksgiving travel trouble will be thanks to a storm that will develop off the Carolina coast and the I-95 corridor is in the bulls-eye.  

The Washington Post's Capital Weather Twitter feed reports we will have snow on the East Coast, but how much has not been totally hammered out days before drivers hit the roads.

Despite the forecast, millions of Americans, about 46.3 million of them will be more than 50 miles from their homes this Thanksgiving weekend, AAA is projecting.  That's the highest volume since 2007 and up more than four percent over last year. 

There is a glimmer of good news though: Gas prices are at the lowest average price in five years -- $2.89 a gallon, AAA reported.

Airports, as is the norm, will be crowded this week.  AAA said that this year will rank as the highest since 2007 for air traffic with 3.55 million people swooping into airports across the country.

And thanks to the potential severe weather blanketing much of the country, air travelers will want to check their flight status, as well as airport statuses, leading up to take-off.

Leave for the airport early, travel experts told the Journal-News.

Greg Wingham suggested in a recent Journal-News article,  if you're a person who leaves an hour before a flight, give yourself at least two hours, give yourself extra time to get through security.

Wingham also suggested to take something to do while waiting, either in line or if your flight is delayed.  Items like magazines, snacks and the ever-present iPad (or other tablets) can help ease the pain of waiting at the airport.

And if the predicted storm does blow in Wednesday, flight delays and cancellations from affected airports could have a ripple effect across the country, even in areas that won't see a flake of snow or a drop of rain.
