A tornado from a bow echo configuration first touched down just west of Greenwood Cemetery on Three Mile Branch in eastern Montgomery (city). The tornado was moving northeastward at approximately 50 mph and moved through the Forest Hills area downing trees and causing minor structural damage to some homes. The tornado crossed the Atlanta Highway and continued to down trees in the Johnstown area of eastern Montgomery. Much of the damage here occurred when trees fell onto structures. The tornado appeared to end on the south edge of Gunter Industrial Park. Several minor injuries were reported.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

6 minutes of warning. NWS BMX issued a tornado warning for this county at 15:16 UTC, 6 minutes before the tornado touched down, in force until 16:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 13:00 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

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.
