The market's unanimous 100% implied probability for an 80-81°F high in Chicago on August 22 aligns with official National Weather Service station observations confirming that exact maximum. Late-summer atmospheric conditions, including moderate humidity levels and absence of strong high-pressure systems, produced a typical diurnal range without exceeding seasonal norms near 82°F. This outcome matches historical climatological baselines for the period, where daily highs frequently settle in the low 80s absent heat-wave advection. Minor variations in measurement timing or station microclimates remain possible but are unlikely to alter the resolved threshold given cross-verified data from primary reporting sites.
