Wider weather episode

Scattered thunderstorms impacted Middle Tennessee during the afternoon and evening hours of June 16, 2025. With above normal atmospheric moisture values, these thunderstorms were capable of producing very heavy rain. This combined with very slow storm motions led to a flash flooding threat. The heaviest rain recorded was in southern Maury County where radar estimates and gauges in the area measured four to five inches of rain. This caused flash flooding in the Culleoka and McCain areas. Heavy rain also impacted Robertson and Sumner counties which caused additional flooding, mainly along creeks and in low-lying areas.
