Recent National Weather Service and private model guidance points to a high near 64°F in Chicago on September 21 under persistent cloud cover and northeast winds, driving the market's heaviest weighting on the 64-65°F bin. A cool air mass following weekend thunderstorms has suppressed temperatures well below the 1991-2020 average high of roughly 74°F, with limited diurnal heating expected from overcast skies and onshore flow off Lake Michigan. Key variables include forecast cloud thickness, any morning shower timing that could further cap warming, and minor model spread in wind speeds. Traders see the distribution across 62-67°F ranges as reflecting lingering uncertainty in the final 48-hour guidance 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 21 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 and private model guidance points to a high near 64°F in Chicago on September 21 under persistent cloud cover and northeast winds, driving the market's heaviest weighting on the 64-65°F bin.
