Official National Weather Service observations at Hartsfield-Jackson Atlanta International Airport (KATL)—the market's resolution source via Automated Surface Observing System data—confirm Atlanta's highest temperature on April 28 reached 71°F or below, driving 100% trader consensus on that outcome as aggregated capital reflects verified measurements. This positioning stems from persistent cloud cover and a cooler mid-level airmass suppressing daytime heating, diverging from pre-event forecasts near 78°F and historical April averages around 77°F. While post-observation quality control rarely revises ASOS readings, an instrument malfunction or data audit correction could theoretically challenge it, though current evidence from NOAA-affiliated stations strongly precludes shifts above 71°F. Traders await final daily climate summary for closure.
