Recent National Weather Service guidance points to a high near 74°F in Chicago on September 17 amid persistent cloud cover, scattered showers, and northeasterly flow off Lake Michigan that limits daytime warming. Model consensus favors modest insolation under mostly cloudy skies, with lake-effect moderation keeping readings cooler near the shoreline than inland while any heavier rain bands could further suppress the peak. Historical September 17 averages near 76°F provide context, yet current synoptic patterns and dew points in the upper 60s support the market's tight clustering around 74–77°F bins. Traders appear focused on the exact official station reading amid these variables, with fresh hourly updates and any last-minute forecast adjustments likely to refine probabilities before resolution.

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 17 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 points to a high near 74°F in Chicago on September 17 amid persistent cloud cover, scattered showers, and northeasterly flow off Lake Michigan that limits daytime warming.
