The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
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 east central Bibb County and determined that it was consistent with an EF0 tornado, with maximum sustained winds near 70 mph.||The tornado began northeast of the city of Centreville in an inaccessible area east of Gary Springs Loop Road, where a well-defined tornado debris signature was observed by the KBMX radar. The tornado tracked eastward and crossed County Road 57 and Pine Tree Road before dissipating near Tucker Road. A few trees were uprooted along the path.
National Weather Service meteorologists surveyed damage in east Bibb County and determined that it was consistent with an EF1 tornado, with maximum sustained winds near 90 mph.||The tornado began on the eastern edge of Brierfield Ironworks Park where several trees were uprooted. The tornado continued eastward and crossed State Route 139. At this location, dozens of trees were snapped and uprooted in the immediate vicinity of Mahan Creek. The tornado tracked eastward and damaged a barn on the Bridlewood Farms property before dissipating just west of County Road 1053.

The forecast that day
The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 00:37 UTC.

What this means
Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
