Heavy rain and thunderstorms are likely for the Southeastern United States this weekend, especially on Sunday. Warm, moist air from the Gulf of Mexico will begin moving northeast through Texas, Arkansas, and Louisiana Saturday and then through Mississippi, Alabama, Georgia, and Florida on Sunday.
The rainfall will be heaviest Sunday and Sunday night for most of the Southeast, resulting in a widespread 1 to 3 inches of rainfall but up to 6 inches in localized spots.
The impacts of this heavy rain will include water ponding on the roadways, minor flooding in low-lying areas, and rises on area rivers and streams. Avoid flooded roadways and turn around if the road ahead is covered in water. Some flooding may occur at night, making it harder to see.
Areas along the East coast should watch where this low pressure system goes after it leaves the Southeast, because it may be close enough to have a snowy influence in parts of the Northeast on Monday night. Right now, a light to moderate wintry mix or plain snow is possible on Monday night. Here’s what the map looks like on Monday afternoon.
As we get closer to next week’s forecast, we’ll have much more detail on the Northeast expectation and impacts.
