The radar
The Northeast Alabama radar (KHTX), 132 km from the middle of the area, began a volume at 00:56 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Peachtre/Fal Fld, GA (KFFC), launched 00:00Z, 0.9 hours before the alert went out and 136 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area Forecast Discussion National Weather Service Peachtree City GA 841 PM EDT Thu Oct 21 2021 .PREV DISCUSSION... /Issued 335 PM EDT Thu Oct 21 2021/ SHORT TERM /Tonight through Friday Night/... Cold front currently stretching from the central Great Lakes down through the Lower Mississippi River Valley. This front will continue to push eastward overnight and into Friday. High pressure will build in behind the front later on Friday. Scattered convection possible along and ahead of the front through the late evening/early morning hours. Currently, convection remains very spotty across the central and southern portions of the CWA. A few lightning strikes have occurred, but mainly south of CSG. Do think on/off sct shra with an isolated thunderstorm is possible this afternoon. The more organized precipitation is expected along the front later this evening into the early morning hours. Not much forcing aloft noted, so main forcing mechanism should the the front itself. Luckily, surface instability should be limited since the boundary is progged to move through after dark for much of the CWA. The far NW corner of the CWA would have the best potential for any stronger thunderstorms during the evening hours. Damaging wind gusts should be the primary hazard. QPF amounts remain very light. For now, pop chances remain too small to mention ahead of the front early tomorrow. Not much cooler air behind the front. Temps will remain around normal through Friday night. NListemaa LONG TERM /Saturday through Thursday/... A pleasant weekend is in store thanks to unexciting quasi-zonal upper-level flow and dry post-FROPA air, as a weak upper-level ridge over the central CONUS shifts eastward and places the CWA in a region of weak subsidence and surface high pressure. Highs will climb from the upper 60s to lower 80s on Saturday to the lower 70s to mid-80s on Sunday as the air mass moderates. The next opportunity for rain will come on Monday as an upper-level trough traverses the Great Lakes region/OH River Valley. The GFS is progging more of an open wave to race across this area amid quasi- zonal flow, while the ECMWF is progging a deeper trough amid meridional flow, and is thus slower with its progression. Maintaining chance PoPs on Monday with a slight chance of thunder. Model discrepancies continue through midweek with different timing/phases in the upper-level wave pattern, though both the GFS and ECMWF are depicting a deep trough traversing the eastern half of the CONUS, bringing another shot at rain across the CWA as Gulf moisture spreads in ahead of it. The GFS is faster than the ECMWF and moves the rain out of the CWA on Thursday night. Given this uncertainty, just carrying slight chance to chance PoPs area-wide Wednesday and Thursday. Martin && .AVIATION... 00Z Update... VFR to MVFR ceilings will become mostly MVFR with the frontal system moving south through the state tonight. The ATL area TAF should begin seeing Precip from this front by 03-04z and it should be done by 06z. Ceilings will lift back into the VFR range by 08z-10z with ceilings clearing by 15z-17z. The CSG, AHN, and MCN TAF sites will see the same thing just a few hours later because of the fronts NE to SW orientation. Winds are out of the SW and will turn to the NW with the frontal passage. Wind speeds will stay 10kt or less through the period. May see some higher gust to 20kt in and around any stronger storms along the front but they will be short lived. //ATL Confidence...00Z Update...
