Current National Weather Service and ensemble forecasts indicate a Friday night low near 56°F for Chicago on September 25, driven by persistent easterly flow off Lake Michigan, extensive cloud cover limiting radiative cooling, and a stable air mass with dew points in the low 50s. These conditions align closely with climatological averages of 54–55°F for the date while suppressing both sharp cold advection that could push readings to 47°F or below and warm southerly flow needed for 66°F or higher. Model consensus shows low spread through the event, with traders pricing uncertainty around minor timing shifts in cloud breaks or wind direction that could alter the overnight minimum by a few degrees.

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 25 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.Current National Weather Service and ensemble forecasts indicate a Friday night low near 56°F for Chicago on September 25, driven by persistent easterly flow off Lake Michigan, extensive cloud cover limiting radiative cooling, and a stable air mass with dew points in the low 50s.
