Persistent northeast winds off Lake Michigan, reinforced by a recent cool front and widespread weekend rainfall, are suppressing daytime heating and positioning Chicago's September 21 high firmly in the low-to-mid 60s. National Weather Service guidance and ensemble forecasts show broad agreement on a maximum near 63–65°F under cloudy skies and continued onshore flow, well below the late-September climatological average of about 74°F. Limited solar insolation from persistent cloud cover and the moderating influence of the lake further reduce the likelihood of exceeding 67°F or dropping below 62°F. With resolution occurring within hours, the market-implied distribution closely tracks this forecast consensus, reflecting traders' assessment of minimal upside risk absent an unexpected shift in steering patterns or model trends.

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.Persistent northeast winds off Lake Michigan, reinforced by a recent cool front and widespread weekend rainfall, are suppressing daytime heating and positioning Chicago's September 21 high firmly in the low-to-mid 60s.
