Official observations from the National Weather Service's Automated Surface Observing System (ASOS) at Hartsfield-Jackson Atlanta International Airport (KATL), the authoritative station for such metrics, recorded Atlanta's highest temperature on May 13, 2026, at 80.1°F around 5:00 PM EDT, peaking after steady afternoon warming from 75.9°F at noon amid partly cloudy skies and light northwest winds. This aligns precisely with pre-event National Weather Service forecasts predicting highs near 80°F under similar conditions, cooler than the 81°F climatological normal due to lingering cloud cover and frontal influences. Trader consensus at 100% implied probability for 80-81°F reflects this verified data, with resolution imminent via final daily climate summary; challenges would require rare data corrections from equipment audits, historically infrequent for ASOS readings.
