Recent National Weather Service forecasts for Chicago on September 20 point to a high in the upper 60s under increasing cloud cover and a 60% chance of showers, driven by northeast winds and an approaching frontal system that limits daytime heating. Model consensus supports this cooler outcome relative to the 74°F historical average, though slight variations in shower timing and intensity across runs create uncertainty around whether the peak reaches the low or mid-70s. Traders weigh these atmospheric details against climatological baselines, with the tight spread across 66–71°F buckets reflecting genuine forecast divergence rather than consensus on any single threshold. Updated model guidance ahead of the date will likely refine probabilities further.

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.Recent National Weather Service forecasts for Chicago on September 20 point to a high in the upper 60s under increasing cloud cover and a 60% chance of showers, driven by northeast winds and an approaching frontal system that limits daytime heating.
