The middle part of June was unusually stormy across the area. Numerous rounds of strong to severe storms impacted the region with multiple squall lines that produced severe winds as well as supercells that produced large hail and tornadoes. Heavy rain also occurred over a multi-day period, which saturated the ground and led to some instances of flash flooding. ||The synoptic pattern featured well above average 250 mb zonal wind anomalies, which were traceable back to an active subtropical jet stream. Greater than average instability was also present, in part due to anomalously warm Gulf of Mexico SSTs. This combination of above average shear from the active subtropical jet and above average instability from the warmer than average SSTs provided a synoptic environment favorable for severe weather as upper level shortwaves moving through the area. This pattern persisted for many days, leading to an unusually large amount of severe weather.

This tornado touched down in a wooded area west of U.S. Highway 431 and uprooted some trees. It then demolished half of a large out building right along the highway removing the roof and collapsing the walls. An adjacent small office building had substantial roof damage. The tornado then crossed Highway 431 and snapped several hardwood trees. As the tornado approached Singletary Road, it destroyed some outbuildings and removed substantial roofing material from two adjacent homes. One of the homes also had some siding removed and the porch was damaged. Several trees were also uprooted in this area. The tornado crossed the other end of a curving Singletary Road, snapping and uprooting more trees. Near the intersection of Singletary Road and W. Washington St., the tornado toppled several concrete memorial monuments. After crossing Washington St. The tornado toppled trees on Marianna Drive and Alberta Drive. Finally, the tornado snapped or uprooted several trees in the vicinity of a cemetery on East Washington St. before lifting short of Eufaula Highway. Damage along the entire path was estimated to be consistent with EF-1 damage with maximum sustained winds around 100 mph.

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 Moderate Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 12:54 UTC.

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.
