Official measurements from the National Weather Service station at Atlanta Hartsfield-Jackson International Airport recorded a daily maximum of 87°F on October 14, 2026, under clear skies and a ridge of high pressure that delivered unseasonably warm conditions. This value falls squarely in the market's 86-87°F bin, producing the observed 100% trader consensus as preliminary climatological data (CF6 reports) aligned with forecast model outputs showing afternoon peaks near that threshold. Historical context places the reading above the 1991-2020 average high of roughly 74°F for the date. Potential challenges remain limited but include final quality-control revisions by NOAA that could adjust the official maximum by a degree or reassign the peak reading to an alternate station within the metro area.
