This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 4 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kord This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent National Weather Service guidance and ensemble forecasts show Chicago-area highs on September 4 most likely reaching the upper 80s to low 90s, with morning clouds and scattered thunderstorms giving way to partial clearing and moderating southwest-to-west winds. Lake Michigan’s influence keeps shoreline readings several degrees cooler than inland sites such as O’Hare, while any lingering convection or increased cloud cover can suppress peak values by 2–4 °F. Historical September 4 averages near 80 °F provide context, but the current warm, humid air mass supports the market’s tight clustering around the 88–93 °F bins; traders weigh the latest model runs and lake-breeze timing against the risk of stronger afternoon heating if storms remain limited.
