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 14 May '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 overwhelmingly favors a high temperature of 56°F or higher in Chicago on May 14 (99.5% implied probability), driven by the National Weather Service Chicago's latest forecast discussion issued early May 13, which projects highs in the 60s to low 70s inland and 50s to near 60°F along Lake Michigan shores under a moderating airmass following a recent cold frontal passage. Model consensus reflects a building surface high-pressure ridge promoting light winds, clearing skies, and radiational warming after yesterday's cooler conditions, aligning with May 14 climatological normals of 69.9°F high. Easterly onshore flow may cap lakefront readings near 60°F, but scenarios challenging 56°F—like unexpectedly stronger lake breezes or persistent low clouds—remain low-probability per current guidance. Next NWS updates this afternoon could refine details ahead of resolution at official observing sites.
