A very moist and unstable environment and strong directional and speed wind shear resulted in an environment favorable for supercell thunderstorms as a warm front tracked northeast through the area. Several supercell thunderstorms erupted during the early afternoon across northwest and north central Alabama, with storms redeveloping through early evening across northeast Alabama. Many of these storms exhibited storm tops that climbed to over 55,000 feet. Nearly all of the storms exhibited a mesocyclone of weak to moderate strength, posing a tornado threat. Numerous photographs were taken by television viewers or newspapers of these storms. The photos indicated recognizable storm structures usually documented by supercell storms including mesocyclones and wall clouds. However, only three tornadoes were confirmed in the Huntsville National Weather Service service area by storm survey, spotter report or photographs.
