National Weather Service observations at Hartsfield-Jackson Atlanta International Airport recorded a daily maximum of 89°F on May 20, 2026, under mostly sunny skies that gave way to scattered afternoon thunderstorms. This official measurement aligns precisely with the market’s 100% implied probability for the 88-89°F range, reflecting the strong consensus among traders monitoring real-time surface data and model guidance. Atlanta’s May climatology typically features highs around 84°F, so the observed value represented a modest positive anomaly driven by clear conditions and southerly flow. Only a significant revision in post-analysis quality control or an undocumented station error could alter the outcome, though historical precedents show such adjustments are rare for this reporting site.
