Trader consensus on Polymarket has locked in 100% implied probability for a 68-69°F high in Chicago on April 27, driven by official National Weather Service observations at O'Hare International Airport (KORD), the resolution station, which recorded a maximum temperature of 68°F at 5:51 PM local time. This measurement from the automated surface observing system aligns with post-event data releases confirming partly cloudy skies, windy conditions with gusts to 36 mph, and no precipitation, slightly above the climatological average high of around 64°F for late April. While final daily climatological summaries rarely revise ASOS readings, a realistic challenge could arise from an official data audit uncovering sensor issues or quality control adjustments, though such corrections are exceedingly uncommon after initial validation.
