Official National Weather Service forecasts for Chicago on September 18 project a high in the mid-70s under mostly cloudy skies with light northeast winds and only a slight afternoon shower chance, limiting daytime heating. Persistent onshore flow off Lake Michigan and widespread cloud cover from recent synoptic patterns have suppressed temperatures relative to earlier September warmth, aligning with model consensus around 74–76 °F. Key differentiating factors include the exact timing of any partial clearing versus lingering stratus or showers, which could shift the daily maximum by a few degrees; historical September variability around the 75 °F climatological average further informs the tight clustering in the 72–77 °F range. Traders appear to weigh these near-term observational and model constraints heavily while assigning modest probability to outlier warming scenarios.

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 18 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.Official National Weather Service forecasts for Chicago on September 18 project a high in the mid-70s under mostly cloudy skies with light northeast winds and only a slight afternoon shower chance, limiting daytime heating.
