Excessive rain in northwest Alabama led to a few reports of flash flooding.  In addition, before the thunderstorms developed, a funnel cloud descended from a building shower near the southern portion of Lake Guntersville in Marshall County.  Multiple photos of the funnel were shared via social media.
