Continuing on a northeastward path, the tornado crossed into Tallapoosa County just south of Sasser road. A few trees were snapped or uprooted along this section of the path. The tornado eventually lifted along Hix Road. In response to a strong upper level shortwave, a surface low developed over the northwestern Gulf of America 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. Start: 32.7438/-86.2996 End: 32.9902/-85.9920
