* 2003: A significant line of thunderstorms plowed through the Tennessee Valley on November 18th, resulting in significant straight-line wind damage. Damaging wind gusts can be just as destructive as tornadoes.
* 2002: The infamous Veteran's Day Tornado Outbreak produced an F3 tornado in Cullman County, which damaged more than 150 structures (check out the storm survey here).
* 2001: Six of the eight tornadoes that hit Northern Alabama this year occurred with the November 24th outbreak. This event broke a record for the number of tornadoes that occurred during a 24-hour period in the state of Alabama.
* Of course, the infamous 1989 Huntsville tornado occurred in November as well. This F4 tornado (207-260 mph winds) tore through south Huntsville on November 15, 1989, touching down on Redstone Arsenal at 4:30pm. The tornado eventually killed 21 people, injured more than 460 people, and caused more than $250 million in damages.
