The primary risk is flash flooding, particularly in areas with already saturated soils, such as Kentucky, which recently experienced Flash Flood Emergencies. Communities in the Ohio and Tennessee Valleys are at the highest risk, with potential for localized rainfall exceeding 5 inches. Training thunderstorms, where storms repeatedly pass over the same locations, will exacerbate the flood threat. The Northeast will also see scattered showers and thunderstorms, though impacts are expected to be less severe. The flash flood threat may extend into next week as the front continues to move slowly south and east.
