Clusters and line segments of heavy thunderstorms, a couple of which turned severe, overspread north Alabama during the predawn hours of the 25th.  These storms produced 2 to 3 inches of rain, mainly south of the Tennessee River, resulting in excessive runoff and flash flooding. Flash flooding closed a portion of I-65 in Cullman and several other roads were flooded or washed out in Cullman County. Also, isolated large hail and damaging winds were reported with a couple of these thunderstorms in northeast Alabama.  During the afternoon hours, additional strong thunderstorms produced additional excessive rainfall resulting in more flooding.  Rainfall totals were in the 3 to 5 inch range, generally south of the Tennessee River corridor.
