Northeast winds and lingering cloud cover from a cool air mass are the main drivers keeping overnight lows in Chicago near the historical 56°F average for September 22. Official forecasts from NWS and model guidance converge on a low of 57°F under partly to mostly cloudy skies, with minimal radiative cooling overnight. This setup favors the tightly bunched 54–59°F outcomes that dominate trader positioning, as small shifts in wind speed or cloud thickness could easily tip the minimum into adjacent bins. Recent cooler-than-normal conditions have reinforced the pattern, though any clearing trend late in the period could allow modest warming toward the upper end of the range.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 22 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.Northeast winds and lingering cloud cover from a cool air mass are the main drivers keeping overnight lows in Chicago near the historical 56°F average for September 22.
