National Weather Service observations from Hartsfield-Jackson Atlanta International Airport (KATL), the official reporting station for such markets, recorded Atlanta's highest temperature on April 18, 2026, at 83°F around 3 PM EDT, driving trader consensus to 100% on the 82-83°F outcome as final data solidified overnight. This peak aligned with pre-event forecasts from NOAA models anticipating warm advection under partly cloudy skies with light southwest winds, amid an early-season heat surge above the April climatological average high of 74°F. While inherent uncertainties in real-time measurements like sensor calibration exist, revisions are exceedingly rare post-verification; only an official data correction from NWS could challenge this positioning, with no such indications in current reports.
