Persistent ridging and subsidence under a strong Bermuda high are sustaining above-normal temperatures across the Southeast, with Atlanta forecast to peak several degrees above the 89°F August climatology. Model consensus from NWS and private guidance centers on a 94–97°F range for August 18, driven by clear skies, light winds, and strong diurnal heating, yet afternoon convection or subtle moisture return could cap the maximum by 1–3°F. Equal market-implied odds across the 88–97°F bins reflect this narrow but uncertain envelope, where small differences in boundary-layer mixing or timing of any showers determine which bin resolves while extremes remain low-probability outliers.
