Heavy rains and thunderstorms in the south and snow in the Pacific Northwest may impact post-Thanksgiving travel as millions hit the roads and descend on airport terminals this weekend.
Most of the country was free of severe weather warnings Saturday morning, and a storm in the south appears to be the most likely source of travel trouble.
The National Weather Service forecast a slight risk of excessive rainfall over parts of the western and central Gulf Coast through Sunday morning, potentially causing localized flash flooding.
On Saturday afternoon, coastal Louisiana and Mississippi faced threats of damaging winds and possible tornados, the regional weather service office said on Twitter.
By Sunday morning, the rain is expected to move into the Ohio and Mississippi Valleys and Central Appalachians before continuing northeastward to the Great Lakes, Northeast and Mid-Atlantic.

Most major cities clear of severe weather
The Thanksgiving travel rush was back on this year, as people caught planes in numbers not seen in years, setting aside inflation concerns to reunite with loved ones and enjoy some normalcy.
As of Saturday morning , the majority of the contiguous U.S. was free of severe weather, with few storm watches or warning, according to forecasts from the weather service.
The East Coast was mostly free of severe weather, as was California on Saturday, the weather service said.
The busiest travel days during Thanksgiving week are usually Tuesday, Wednesday and the Sunday after the holiday. This year, the Federal Aviation Administration expects Tuesday to be the busiest travel day with roughly 48,000 scheduled flights.
But with flightaware.com reporting only a few dozen cancellations of flights within, into or out of the U.S. as of Saturday morning, air travel is starting the weekend without major disruptions.
