Official National Weather Service forecasts and supporting model guidance indicate a high in the upper 60s for Chicago on September 20, driven by lingering cloud cover, scattered showers, and persistent northeast winds of 15–20 mph with gusts to 30 mph that limit surface heating and advect cooler air. This setup follows an active Saturday system and deviates below the 1991–2020 average high of 74°F. The near-even market split between 68–69°F and 70–71°F reflects minor uncertainties in exact precipitation timing, cloud breaks, and boundary-layer mixing that could nudge the peak by a degree or two. Updated model runs and NWS briefings ahead of the daytime period will provide the clearest signals for 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 20 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.Official National Weather Service forecasts and supporting model guidance indicate a high in the upper 60s for Chicago on September 20, driven by lingering cloud cover, scattered showers, and persistent northeast winds of 15–20 mph with gusts to 30 mph that limit surface heating and advect cooler air.
