Official National Weather Service forecasts for Atlanta on August 28 point to a daytime high near 90–91 °F under partly sunny skies, with patchy morning fog giving way to light northwest winds and a 30 % chance of afternoon showers or thunderstorms. This consensus from the Peachtree City office and supporting model guidance underpins the strong market weighting on the 90–91 °F bin. Thunderstorm timing and coverage remain the chief variables that could trim the peak by a degree or two if convection arrives earlier or produces more widespread cloud cover and outflow. Current observations show temperatures climbing from the low 70s at dawn, consistent with the projected afternoon maximum on the Saffir-Simpson–adjacent heat scale for late-summer conditions in the region.
