Within an unseasonably warm and moist low-level environment, a strong southwest upper level flow with an intense mid-level shortwave ejecting across the Central Plains/Midwest regions resulted in a line of strong to severe thunderstorms (along with heavy rain) across north Georgia during the evening and overnight hours of 29-30 December 2021. The remnant boundary/front settled over central Georgia during the afternoon of 30 December 2021 which resulted in redevelopment of scattered strong to severe thunderstorms. Several tornadoes, along with areas of wind damage and large hail occurred all across north and central Georgia from these events. Rainfall amounts of 3 to 6 inches occurred over the area, resulting in isolated flash flooding in the greater Atlanta metro area.

This tornado touched down shortly after entering Pulaski County and began uprooting several trees on Mock Springs Rd. Traveling eastward, light damage was observed through several dirt roads including a covered awning that was completely destroyed on Fire Rd 624. The tornado continued eastward crossing Hwy 27 and HWY 257, where several trees were snapped and uprooted and minor damage to several homes which included removed vinyl siding, pierced vinyl siding by tree branches, removed gutters and shingles, and damage to a front porch awning. As the tornado crossed near Wallace, an open barn with with sheet metal roofing was also destroyed south of the Big Creek bridge on HWY 129. The tornado then moved across a swampy undeveloped area and maintained a TDS signature until passing over the Ocmulgee River, approximately 5 miles south of Hawkinsville. The tornado then dissipated over the wetland with no reported damage on the eastern side. [12/30/21: Tornado #4, County #1/1, EF-0, Pulaski, 2021:26].

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a severe thunderstorm watch, issued at 19:05 UTC and running to 02:00 UTC.

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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:56 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.
