This market will resolve to the temperature range that contains the highest temperature recorded at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 29 Mar '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Chicago O'Hare Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/il/chicago/KORD. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket centers implied probabilities around 60-65°F for Chicago O'Hare International Airport's highest temperature on March 29, with 62-63°F leading at 26%, driven by the latest 12z GFS and ECMWF ensemble means forecasting mild south-southwesterly flow ushering Gulf-sourced air masses northward amid a neutral-to-weak La Niña pattern. This setup exceeds the late-March climatological average high of 52°F per National Weather Service normals, supporting above-normal readings during peak afternoon heating. Close odds reflect scientific uncertainty in boundary-layer mixing efficiency and low-level cloud persistence, which could cap peaks at 60-61°F or allow 64-65°F if skies clear more fully; watch National Weather Service updates and tonight's 00z model runs for refinements ahead of resolution.
