**Official National Weather Service forecasts for Chicago issued on September 12, 2026, project an overnight low near 64–65°F under partly cloudy skies with light northwest winds, supporting the strong market consensus around 66–67°F as the daily minimum.** This aligns with observed conditions featuring mild southerly flow earlier in the period transitioning to clearer, drier air that limits further cooling, keeping temperatures above the late-summer climatological average low near 60°F. National Weather Service point forecasts and ensemble guidance show limited spread, with minimal risk of radiational cooling below 63°F given the expected cloud cover and wind. A realistic challenge would require unexpected clear skies and calm conditions promoting stronger surface cooling, or a shift in the official station reading (typically O’Hare) that places the minimum in the low 60s. Updated model runs or post-sunset observations could refine this before final resolution.

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 12 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.**Official National Weather Service forecasts for Chicago issued on September 12, 2026, project an overnight low near 64–65°F under partly cloudy skies with light northwest winds, supporting the strong market consensus around 66–67°F as the daily minimum.** This aligns with observed conditions featuring mild southerly flow earlier in the period transitioning to clearer, drier air that limits further cooling, keeping temperatures above the late-summer climatological average low near 60°F.
