A potent upper level trough of low pressure and strong upper jet streak pushed through the Tennessee Valley on the 26th. Unseasonably high temperatures in the upper 70s to lower 80s and dew points in the upper 60s to near 70 produced an unstable environment. Deep layer shear was sufficient for supercell thunderstorms, while low level shear was quite strong as well. As a result, numerous supercell thunderstorms, many of them low topped, erupted in multiple bands across northern Alabama as early as late morning and lasted into the early evening hours. The storms brought the potential for severe weather for around eight hours. Many of the storms contained meso-cyclones, but only four produced brief weak tornadoes. Others produced wind damage associated with the rear flank downdrafts of the storms or with bowing segments.
