Recent forecasts from the National Weather Service and models indicate a high near 64–65°F for Chicago on September 21, driven by a cooler northeast flow behind a frontal passage and widespread cloud cover that limits daytime heating. Persistent showers or drizzle, combined with gusty northeast winds of 15–20 mph, further suppress the maximum by enhancing mixing and reducing insolation. This setup contrasts with the seasonal average high of roughly 74°F, reflecting a stronger-than-normal maritime influence from the Great Lakes region. Traders’ near-even split between the 62–63°F and 64–65°F bins captures residual uncertainty in the precise peak, which hinges on the timing and intensity of any morning showers versus partial afternoon clearing. Updated model runs and National Weather Service briefings in the next 48 hours will likely narrow the range.

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 21 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 forecasts from the National Weather Service and models indicate a high near 64–65°F for Chicago on September 21, driven by a cooler northeast flow behind a frontal passage and widespread cloud cover that limits daytime heating.
