The National Weather Service's official observation at Chicago O'Hare International Airport (KORD) recorded a high temperature of 48°F on April 19, 2026, driving trader consensus to a 100% implied probability for the 48-49°F outcome as the market nears resolution. This below-normal peak—against an April 19 average of 60°F—stemmed from a cool upper-air mass, gusty winds limiting surface heating, and lingering effects of recent frost advisories, overriding pre-event forecast models that clustered around 49-51°F. Verified airport Automated Surface Observing System data confirms the reading, with no significant hourly deviations above 48°F. Resolution could only shift via rare NWS data correction, pending final climatological report.
