The highest risk of flash flooding Tuesday and Tuesday night will be in parts of southern Kentucky, West and Middle Tennessee, northern Mississippi and northern Alabama, according to NOAA's Weather Prediction Center.

Isolated flash flooding is also not ruled in parts of the Northeast, where 1 to 2 inches of rain could fall through Tuesday night, particularly across the western Pennsylvania ridges, the Poconos of northeastern Pennsylvania, the eastern Catskills and Adirondacks of New York and the Green Mountains of Vermont.
