A very warm and moist air mass developed over Central Alabama on Monday, December 16th. Afternoon temperatures warmed into the lower and middle 70s, which was 15 to 20 degrees above normal for the middle of December. A surface low tracked north of Alabama Monday night and pushed a strong cold across the state. Several bands of strong to severe storms developed across Mississippi during the afternoon and moved into west Alabama that evening. Most of the severe weather damage across Central Alabama was associated with a long track supercell that started in Mississippi and tracked into southwest Alabama. The supercell entered southern Sumter County and tracked northeast to Shelby County.

National Weather Service meteorologists surveyed damage in extreme northwest Marengo County and determined that it was consistent with an EF2 tornado, with maximum sustained winds near 120 mph.
The tornado first touched down along County Road 28 where minor tree damage was noted on the east side of the road. The tornado tracked northeast over mainly forested areas of Marengo County for several miles producing sporadic tree damage. The tornado widened and strengthened rapidly as it continued northeast toward Highway 80. The tornado reached its widest point near Highway 80. Substantial tree damage was noted on both the north and south sides of Highway 80 along and near the intersection of County Road 57. A home sustained roof damage along County Road 57.  On the north side of Highway 80, property and structural damage was extensive. Several homes sustained roof and structural damage. One brick home sustained complete roof loss and partial wall collapse.
Just east of that location, a single-wide and double-wide manufactured home on the same property were completely destroyed with the undercarriage of both blown a substantial distance. Inspection of both dwellings indicated little to no anchorage of the structures. Three people were reported injured at this location with one being airlifted for more serious injuries. Tree damage in this area was extensive with large old growth hardwoods snapped. The combination of the damage to the conventional brick home, along with the tree damage and manufactured home destruction, prompted the maximum wind rating of 120 mph. The tornado continued its northeast movement damaging additional structures north of Highway 80 before narrowing and weakening south of the Sumter County line, just west of downtown Demopolis.
