A strong upper level storm moving across the Mississipi Valley brought a dry line and cold front into north Alabama during the afternoon and early evening hours. Several classic supercell thunderstorms developed by early afternoon in northwest Alabama, sweeping across the remainder of north Alabama during mid to late afternoon hours. Many of the storms produced very large hail, up to baseball and softball sized, producing significant damage, especially from Decatur through Madison and northwest Huntsville. One of the supercells produced a long track tornado producing damage of up to EF-3 intensity which struck northeastern Marshall County, crossed Lake Guntersville, and moved into southern DeKalb County.
