AAA says 3.5 million will fly this Thanksgiving, the highest level since 2007, and another 41.3 million will travel by automobile.  The only problem is that the weather on Wednesday along the I-95 corridor from Maine to South Carolina could include rain, sleet, and accumulating snow depending on a coastal low developing, and a mass of cold Canadian air that will push temperatures down, and the likelihood of snow up.

NOAA precipitation prediction shows a strong low off pressure system off the Eastern Seaboard for Wednesday November 26th, 2014.

Initially, the storm is forecast to spread steady rain and thunderstorms across the Florida Peninsula on Tuesday through Tuesday evening. Then the predictions is that on Tuesday night through the start of Thanksgiving the storm will turn northward and impact the rest of the East Coast. The precise impacts from the storm will be determined by the exact track the storm takes along the East Coast.

Bottom Line:

There is a lot of uncertainty surrounding this storm, and computer forecast models vary widely.  If your travel plans this Thanksgiving week include the East Coast, be sure to check weather.com, AccuWeather.com, or the National Weather Service for more specific impacts as we head towards one of the busiest travel periods of the year.
