**Persistent high pressure over the Southeast is sustaining a late-summer heat wave, keeping Atlanta under mostly sunny skies with strong daytime heating and minimal cloud interference expected through August 19.** Official NWS and model guidance converge on a high near 94–97 °F, roughly 5–8 °F above the 89 °F August climatological normal at KATL. Key differentiating factors include the strength of subsidence warming, boundary-layer moisture that modulates afternoon convective cloud development, and light steering winds that limit mixing. Any increase in scattered thunderstorms or a slight westward shift in the ridge axis could cap the maximum 1–3 °F lower, while clearer conditions and stronger downslope flow would favor readings at the upper end of the guidance envelope. Updated NWS point forecasts and afternoon model runs will provide the next clear signal ahead of market resolution.
