**Forecast consensus points to an overnight low in the low-to-mid 70s°F for Atlanta on August 31, 2026, aligning with the tightly clustered market leaders at 72–73°F and 74–75°F.** Late-August high pressure and light easterly winds under mostly clear to partly cloudy skies favor moderate radiative cooling, though elevated dew points near 70°F and urban heat retention limit drops below the historical average low of ~69–71°F. Recent model runs show little spread in minimum temperatures, with guidance converging on 72–76°F depending on exact cloud timing and boundary-layer mixing. Traders appear to weight the most probable narrow range while discounting cooler outliers absent stronger cold advection or clearer skies. Updated National Weather Service guidance and evening observations will refine the final recorded minimum at official stations.
