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 13 Apr '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.National Weather Service forecasts project Chicago's high temperature at O'Hare International Airport, the official measuring site, reaching 77-78°F this afternoon under partly sunny skies with southerly winds aloft, propelling market-implied odds to full consensus on 74°F or higher. Current observations show midday readings climbing into the low 60s°F amid light showers clearing, aligning with model consensus from NOAA's High-Resolution Rapid Refresh runs that favor rapid warming well above the April 13 normal of 58°F. This positioning reflects strong scientific agreement on persistent warm air advection, though realistic challenges include intensified scattered thunderstorms capping insolation or an unexpected cold front surge, with final hourly data releases determining resolution by midnight.
