Trader consensus on Polymarket assigns 100% implied probability to a 70-71°F high in Atlanta on March 28, backed by the National Weather Service's official climatological observation of exactly 70°F at Hartsfield-Jackson Atlanta International Airport (KATL) around 4 PM EDT, measured via the site's Automated Surface Observing System under fair skies with no precipitation. This outcome followed a remarkably warm early March 2026—featuring multi-day highs near 83°F amid a positive temperature anomaly 20°F above normal—but a cooling front ushered lighter winds and partial cloud cover, capping daytime heating as forecast by GFS and NAM ensemble models. Scenarios challenging this include rare data audits revealing sensor errors, though KATL records are authoritative and revisions are exceptional.
