A stray shower or two is possible all across the Tennessee Valley through about 7 PM on our Wednesday evening. Those showers will be few, and most of the Valley will stay dry.
A storm system we have been tracking over the Great Plains is our next weather maker. It will bring rain to the Tennessee Valley starting Thursday. The morning will be dry. Rain will begin increasing between noon and 2 PM across the Shoals, then from 2 PM through 4 PM from I-65 around Athens and Decatur to Huntsville and Fayetteville, then between 4 PM and 6 PM across Sand Mountain. Rain may be somewhat spotty initially, so some areas may stay dry on Thursday. If you need to get yard work done on Thursday, before noon is best since rain will begin increasing in the afternoon.
Rainfall amounts through Tuesday will add up to 2-3".
Rain will become more widespread and track across the Tennessee Valley in waves on Friday. Expect these periodic bouts of rain with occasional dry breaks to last through Tuesday morning. Rain will break up Tuesday afternoon. The sun will return on Wednesday, and temperatures may take a hard drop.
