Official observations from Atlanta-area stations, including Hartsfield-Jackson International Airport, recorded an overnight minimum of approximately 60–61°F on October 13, 2026, under clear skies, light northwest winds, and surface high pressure that limited radiational cooling. This aligns with National Weather Service climatological data showing typical early-October lows near 56°F but elevated by persistent warm advection and dew points in the mid-50s that moderated temperature drops. The near-100% market consensus on the 60–61°F bin reflects these verified readings, with minimal model or observational uncertainty. A colder outcome would have required stronger northerly flow or clearer, drier conditions promoting greater heat loss, scenarios not supported by the observed pressure and wind patterns.
