Trader consensus on Polymarket has locked in a 100% implied probability for a highest temperature of 40-41°F in Chicago on April 1, 2026, driven by official National Weather Service observations from Chicago O'Hare International Airport (KORD), the market's resolution source, recording a daily maximum of 40°F. This outcome reflects verified surface measurements under persistent north-northeast winds at 15-20 mph and overcast skies, which suppressed solar heating and trapped a shallow cold air mass after late-March warmth peaked at record 87°F on March 30. Early April climatological normals hover around 53°F highs, making this reading 13°F below average amid model consensus for cooldown post-warm front. Scenarios challenging this would require rare NOAA data revisions from instrument audits or quality control, improbable given rigorous hourly METAR validations; markets await no further updates as resolution nears finality.
