Latest National Weather Service guidance and ensemble model runs project a mostly sunny to partly cloudy day with highs centered in the mid-90s Fahrenheit for Atlanta on August 15, driven by weak westerly flow, moderate Gulf moisture, and daytime heating under a building ridge. The near-even split between the 94-95°F and 96-97°F bins reflects uncertainty over whether scattered afternoon convection will initiate early enough to cap temperatures or whether clearer conditions will allow additional warming. Key differentiators include the precise timing and coverage of thunderstorms, boundary-layer mixing depth, and urban heat-island effects around the official observing site; any delay in storm development or stronger insolation could push readings into the upper half of that range while earlier or more widespread activity would favor the lower half.
