As Thanksgiving approaches, travelers across the eastern United States are facing the prospect of challenging weather conditions. A major storm system has descended upon the region, bringing heavy rain, thunderstorms, and even snow in some areas. The inclement weather is expected to cause delays, both in the air and on the ground, during one of the busiest travel periods of the year.

The storm, which began on Monday, unleashed tornadoes and damaging thunderstorm winds in Louisiana and Mississippi. It also brought heavy rain to the Mid-South and Tennessee Valley, offering some respite to drought-plagued regions. However, this relief may come at a cost for Thanksgiving travelers.

Tuesday and Tuesday night are expected to be the most affected by the storm, with soaking rain anticipated in the drought-stricken Appalachians and Mid-Atlantic. In the Southeast, thunderstorms are expected, while the interior Northeast may experience snowfall. This combination of adverse weather conditions could lead to significant disruptions in travel plans.

On Wednesday, the storm's focus will shift to New England, where rain and mountain snow may cause interference with travel. Some downpours are also possible along the Southeast coast and in Florida. However, as Thanksgiving arrives, most of the country should experience settled weather, except for the northern Rockies and adjacent High Plains. These areas may face a significant snowstorm due to a blast of cold air.

Despite earlier concerns, the likelihood of another disruptive storm in the East during the weekend has diminished. However, some rain is possible along the northern Gulf Coast and in Florida, which may affect travel plans for those in the area.
