Official observations from Chicago O'Hare International Airport, the National Weather Service's primary station for the city, recorded a high temperature of 44°F on March 27, 2026—well below the historical March average of 51°F—driving trader consensus to 100% implied probability for the 44-45°F outcome. Persistent cloud cover, northerly winds, and a stable upper-level trough suppressed warming, aligning with final GFS and European model guidance that had converged on this range in the preceding 24 hours. This skin-in-the-game positioning reflects verified hourly data, with resolution imminent upon NWS climate summary release; challenges would require anomalous sensor recalibration or metadata discrepancies, which are exceedingly rare for established automated stations.
