I plant a modest fall crop of potatoes about Labor Day for an early December harvest here in Gainesville, Florida. I then plant my main crop of potatoes (using freshly bought seed potatoes) in mid January for a late May harvest. Anything harvested from my main crop that is starting to sprout by Labor Day gets planted for the fall crop since fresh seed potatoes are not available locally at that time of year.

The first frost of the autumn generally occurs here between Thanksgiving and the first week in December, which allows about 90 days for my fall potatoes to mature. You would need to adjust your summer planting date accordingly -- I would guess around mid to late July for the Atlanta area. Just don't count on a huge crop of fall potatoes. I use them as a supplement to my main crop, which is planted in January. If you want to grow lots of potatoes, then plan for that to be the spring crop.

If finding seed potatoes in mid summer is problematic for you, you can always try grocery store potatoes that have sprouted or stash some spring bought seed potatoes in the refrigerator until you are ready to plant them in July.
