Christmas Day Tornadoes of 2012

Event Summary for Central Alabama

As part of a two day event, with severe weather stretching from Texas to North Carolina and heavy snowfall across the center of the country, Central Alabama experienced a wide range of severe weather on Christmas Day.  Late Christmas Eve, a well amplified upper level trough dug into the southern plains.  In response, a surface low developed Christmas morning over southern Texas.  As the upper low deepened it tilted negatively and helped to deepen the surface low as it moved eastward.  By Christmas afternoon, a swath of severe weather swept across the deep south, with discrete supercells and a broken line of thunderstorms in trail.  These thunderstorms moved across east Texas, Louisiana, and south Mississippi during the afternoon hours, and then into south and central Alabama during the evening hours, bringing with them strong straight line winds, numerous tornadoes, as well as flooding.  The tornado accounts below are specifically for the counties of Central Alabama.

The tornado damage "swaths" as depicted in the image above, and on the individual tornado links, are an estimate of the damage widths along the track.  In other words, the track width may not represent the actual damage in all locations, as we interpolate the values between actual surveyed damage points.  These maps are soley for the purpose of showing the general track of each tornado.  Remember, tornadoes do not always move in straight lines, and the intensity does not remain constant.  It is also possible to have other thunderstorm wind-related damage in close proximity to the tornado tracks from such features as inflow and rear flank downdrafts, which can produce tornado-like damage.
