Recent National Weather Service forecasts indicate an overnight low in the mid-60s for Chicago on September 18, with model consensus centering around 64–68°F amid persistent cloud cover, scattered showers, and easterly flow off Lake Michigan. These conditions limit radiational cooling and maintain higher dew points near 60°F, elevating minimum temperatures above the 1991–2020 climatological average of 57.7°F. Trader-implied odds cluster tightly on the 64–69°F bins because ensemble guidance shows only modest spread in boundary-layer moisture and wind speeds, with little evidence for stronger cold advection. Key resolution factors include the precise timing of any clearing overnight and official thermometer readings at O’Hare or Midway, both of which will be finalized by early September 19.

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 18 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.Recent National Weather Service forecasts indicate an overnight low in the mid-60s for Chicago on September 18, with model consensus centering around 64–68°F amid persistent cloud cover, scattered showers, and easterly flow off Lake Michigan.
