AccuWeather reports as millions of Thanksgiving travelers plan to travel by plane or driving, quick-hitting storms will cause slowdowns across different regions of the United States.

Nearly 51 million Americans will travel more than 50 miles away from home for Thanksgiving, according to AAA. This represents a small increase from 2016.

New information suggests the weather pattern is much less likely to lock into a cold and stormy pattern through the Thanksgiving weekend across the Northern states. Meanwhile, multiple days of unsettled conditions may evolve in the Deep South.

“Weather systems are now more likely to keep moving along, rather than stall across the northern half of the nation over the next week to 10 days,” according to AccuWeather chief meteorologist Elliot Abrams.

With this more progressive idea, there will still be blasts of chilly air and rounds of lake-effect snow. However, cold outbreaks will be limited to a couple of days and storms will tend to be weaker and swept along by the fast flow of air.

As Thanksgiving travel ramps up, one storm will sweep across the nation today to Sunday.

On Friday night and Saturday, drenching rain and locally heavy thunderstorms are forecast from the middle Mississippi Valley to the lower Great Lakes region.

Motorists may have to slow their commute and rely heavily on their windshield wipers. Airline passengers from St. Louis to Nashville, Cincinnati, Cleveland and Pittsburgh may face some turbulence and delays.

The same storm will race across the Eastern states Saturday night to Sunday. Over the Appalachians and in the coastal mid-Atlantic and New England, several hours of rain are in store. There may be a rumble of thunder.

People catching flights Saturday night to Sunday morning from Washington, D.C., to New York City and Boston may experience some delays.

In parts of the Appalachians, the rain may end as a brief period of snow.

East of the Appalachians in the South, a singular gusty shower may mark the arrival of the chilly air in lieu of long-lasting rain during Saturday night.

Gusty winds will force motorists to keep a firm grip on the steering wheel in the Upper Midwest and Northeast this weekend and could add to airline delays at some airports.

Wet weather may be in store for portions of the mid-Atlantic and New England coasts by Tuesday night, should a batch of rain be pulled in from the Atlantic.

“Any rain to start the day on Wednesday in the coastal Northeast is likely to end during the morning,” according to AccuWeather senior meteorologist Kristina Pydynowski. “However, this may be enough to put some airlines behind schedule for the day and may lead to ripple effects across the nation as the day progresses.”

During the middle part of next week, moisture is likely to gather around the Gulf of Mexico as a storm slowly brews.

Rainfall associated with this storm is forecast to expand northward and eastward but only to a certain point in the Southern states.
