Persistent cloud cover, showers, and northeast winds off Lake Michigan are moderating overnight radiative cooling in Chicago on September 17, keeping the daily minimum near the mid-60s rather than allowing a sharper drop. Official NWS and model guidance show lows around 66°F amid high humidity and limited clear-sky periods, though localized variations near the lake or brief clearing could push readings lower. Historical September averages near 58°F highlight how the current pattern deviates from typical fall cooling. With market-implied odds nearly even between the 66-67°F bin and 59°F or below, traders are weighing the strength of this marine influence and any late-day forecast adjustments against the possibility of greater overnight clearing.

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 17 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.Persistent cloud cover, showers, and northeast winds off Lake Michigan are moderating overnight radiative cooling in Chicago on September 17, keeping the daily minimum near the mid-60s rather than allowing a sharper drop.
