A First Alert Weather Day is in effect through Thursday evening as storms build across Middle Tennessee and southern Kentucky, with Nashville’s best chance for rain and thunderstorms coming from 7 p.m. to 10 p.m. The strongest storms could bring wind gusts over 50 mph, hail and heavy rain.
The greatest storm threat is expected to hit western Middle Tennessee and southwest Kentucky between 5 p.m. and 8 p.m., then move southeastward into the Nashville area and on toward the Cumberland Plateau later in the night. A few showers may pop up early Thursday, but the main concern is the late-afternoon and evening round of storms that could easily produce downpours.
Tornadoes are unlikely, but the weather risk stretches beyond Nashville to much of Middle Tennessee and southern Kentucky, where brief gusty wind and hail are fair game with any stronger cell. For Nashville, the key window is the evening commute into the night, when storms are most likely to arrive and the heaviest rain is most likely to fall.
By the time the system reaches the Cumberland Plateau between 9 p.m. and midnight, the worst of the threat should already be shifting east. The headline today is not that a major outbreak is expected. It is that a sharp line of storms could still pack enough punch to make Thursday evening messy, noisy and fast-changing across the region.
