Trader consensus on Polymarket has locked in 70-71°F at virtually 100% implied probability for Atlanta's highest temperature on April 19, driven by official observational data from the Hartsfield-Jackson Atlanta International Airport (KATL) station, as reported by Weather Underground—the market's resolution source. Verified hourly records show a peak in this range amid cooler conditions, with overnight temperatures dropping to the mid-50s°F, following a frontal boundary that suppressed daytime heating after warmer precedents like 83°F on April 18. National Weather Service timeseries corroborate the maximum around early afternoon. With data finalized, challenges would require rare measurement revisions from auditing agencies; no significant discrepancies have emerged. Climatologically, this sits slightly below April's average high of ~74°F due to persistent cloud cover and northerly winds.
