Event Narrative

National Weather Service meteorologists surveyed damage in Bibb County and assessed damage that was consistent with a tornado.

Episode Narrative

In response to a strong upper level shortwave, a surface low developed over the northwestern Gulf of Mexico and rode along a previously stalled front across northwest Central Alabama, Thursday, December 22, 2011. Much of Central Alabama resided in an unseasonably warm airmass, with dewpoints near 70 degrees and CAPE over 1000 J/kg. As the surface low passed over northwest Central Alabama and low level winds backed, helicity increased. Rotating supercells within several thunderstorm complexes produced six tornadoes and isolated wind damage.
