Ash Anthracnose, which is an uncommon problem in this area, has been seen in Tennessee. If you have Ash trees, look for leaf damage. This disease could defoliate your tree. "Additional symptoms include brown to black blotches on leaf margins, causing leaf distortion and small purple to brown spots in the middle of leaves. Several successive years of heavy defoliation may cause twig and branch dieback. Trees that lose leaves in spring will often grow new leaves." Refoliated leaves are often smaller and the crows of affected trees may appear thin."
