Several ingredients, including:
- a warm and unstable airmass,
- wind shear in the low levels
- strong upper level winds
- and a cold front pushing into the state
...combined to bring severe thunderstorms and tornadoes to a large portion of North and Central Alabama Sunday night and early Monday morning. Several destructive tornadoes in the north half of the state caused widespread damage and numerous fatalities and injuries.
Meteorologists from the National Weather Service conducted extensive on-site surveys of the destruction caused by the tornadoes. While the initial estimate was 12 to 15 tornadoes, we now believe that 11 tornadoes actually occurred. The tornado count was reduced primarily because of the long track nature of two of the most intense storms.
The following table contains the essential information on each of the tornadoes, presented chronologically. The tornado names link to separate pages with details concerning each tornado, including damage path maps and photos.
