National Weather Service observations at Chicago O'Hare International Airport (KORD) recorded a maximum temperature of 40°F on April 1, 2026, well below the 53°F climatological normal, driving the market's 100% implied probability for the 40-41°F outcome as traders locked in on verified Automated Surface Observing System (ASOS) data. This chill stemmed from a persistent cool air mass and windy conditions under partly cloudy skies that suppressed daytime heating after a mild, wet March pattern. Forecast models from NOAA had anticipated highs near 41°F in the preceding 24 hours, aligning closely with the outcome. Realistic challenges would require rare NWS data revisions due to sensor anomalies, but rigorous quality controls render this highly unlikely.
