Official observations from Hartsfield-Jackson Atlanta International Airport (KATL), the standard measurement site, recorded a maximum temperature of 84°F on April 15, 2026, at around 4-6 PM local time under partly cloudy skies with light southwest winds and no precipitation. This aligns precisely with pre-event National Weather Service forecasts and NOAA model consensus, which projected low-to-mid 80s highs as a persistent upper-level ridge weakened ahead of an approaching cold front, tempering earlier record heat from April 13-14 (85°F). Well above the historical April 15 average of 74°F but below the record 87°F, the market-implied 100% odds on 84-85°F reflect verified ASOS data; challenges would require rare post hoc quality control revisions by NOAA.
