A strong upper low pressure system and associated surface front brought a squall line of storms across the area during the late afternoon and evening hours of Wednesday, November 18. While instability for storm development was low, there was strong wind shear in place which increased the threat for isolated tornadoes and damaging winds. Three tornadoes formed in the northern part of a pronounced bowing segment along the squall line as it tracked across northern Coweta County and southern Fulton County shortly before 5 PM and into DeKalb County around 5:45 PM. The first two tornadoes resulted in EF-1 rated damage, with one near Palmetto and another near Fairburn. The final tornado was a very brief EF-0 in DeKalb County near Tucker (specifics listed below). These storms still dumped heavy rainfall and produced damaging winds in isolated locations across the remainder of the Atlanta metro area.
Coweta County:
A very short-lived tornado touched down in the Wynn Manor subdivision off Tommy Lee Cook Rd in northern Coweta county. Structural damage to at least five homes was noted along George Wynn Rd with the most significant damage occurring to house on the corner of Lea Way and George Wynn. At this location, a portion of the roof and front porch were lifted and thrown nearly 50 yards away. This is where maximum winds of 105 mph were reached which resulted in the EF-1 rating.
Additional damage included fences blown over with 4 by 4 beams snapped near the base. Several smaller trees were snapped but these homes were not surrounded by a wooded area. The tornado was only down for less than a minute as the storm moved northeast toward the Coweta/Fulton county line.

Fulton County:
A secondary tornado spun up from the same system and initially touched down near Creekside High School where minor damage was seen at the football field to the goal posts and bleachers. Around Durham Lakes Country Club, several large pine trees were uprooted as the tornado became better organized. Near the intersection of Virlyn B. Smith Rd and Dynasty Dr, there was roughly a 120-yard wide area where numerous large trees were snapped and uprooted around several homes. The homes only sustained minor roof/siding damage. There was a small unsecured shed that was ripped apart by the winds. Just ahead along Tell road, additional large trees (mainly pines) were snapped near their bases. The tornado continued to track northeast snapping trees along Rivertown Rd just north of Clarence Duncan Park. Along White Bird Way which turns into Tall Deer Dr, trees were snapped and uprooted with several homes sustaining significant damage from falling trees. The same damage was seen along Small Elk Ct. The tornado likely reached its peak intensity between this location and Virlyn B. Smith Rd with maximum winds estimated around 95 mph, leading to its EF-1 rating. The tornado rapidly weakened and lifted before reaching West Campbellton St, just north of Fairburn city limits

Dekalb County:
A very brief EF-0 tornado touched down near Tucker in DeKalb County at 5:47 PM EST and was on the ground for less than a minute. This tornado caused structural damage to two locations along Hammermill Road just off US-78E. The front part of a north-facing wall was ripped apart at one location, while part of the roof and metal siding were peeled back on another building directly across the street. The only other damage in this area consisted of two uprooted pine trees. Maximum sustained winds were estimated at 75 mph, consistent with the EF-0 rating.
