The National Weather Service's official climatological report confirms Atlanta's highest temperature at Hartsfield-Jackson Atlanta International Airport (KATL) reached exactly 70°F on March 28, 2026, at 3:53 PM EDT under clear skies, light winds, and dry conditions amid a Red Flag Warning, driving trader consensus to 100% on the 70-71°F outcome. This aligns precisely with pre-event ensemble model consensus from NOAA's GFS and NAM forecasts projecting upper 60s to low 70s, just 1°F above the 1991-2020 March climatological normal of 69°F following an unusually warm month trending 20°F above average earlier. Scenarios challenging this near-certainty, such as rare post-validation data revisions from supplemental observations, remain highly improbable given validated official measurements.
