The episode as NWS HUN wrote it up.
A band of low topped supercell thunderstorms developed in north central Alabama during the morning hours along a pre-frontal trough line. The near storm environment was characterized by deep layer wind shear, but very limited instability. The cells tracked northeast into northeast Alabama producing small hail up to dime size and gusty winds. The strongest thunderstorm developed a mesocyclone which produced wind damage between the towns of Henagar and Ider in DeKalb County just after 11:00 am CDT.
