Recent National Weather Service forecasts and supporting model guidance position the highest temperature in Chicago on September 18 around 71–74°F, with trader consensus favoring 72–73°F. Persistent cloud cover, easterly winds off Lake Michigan, and limited daytime heating from a stable air mass are expected to hold highs below the late-September climatological average of roughly 75°F. Official outlooks cite mostly cloudy skies and a high near 71°F under east winds of 5–15 mph, while private guidance clusters in the low-to-mid 70s. This setup explains the narrow distribution around the 72–73°F bin and limited probability assigned to warmer or cooler outcomes, pending any last-minute forecast adjustments before resolution.

This market will resolve to the temperature range that contains the highest 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 highest 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 and supporting model guidance position the highest temperature in Chicago on September 18 around 71–74°F, with trader consensus favoring 72–73°F.
