Recent National Weather Service and model guidance point to a high of 64–65°F for Chicago on September 21, driven by a cooler northeast flow behind Saturday’s system and widespread cloud cover that limits daytime heating. Persistent onshore winds of 15–20 mph with gusts to 25 mph, combined with a 30% chance of morning showers, are expected to cap afternoon temperatures in the mid-60s. This represents a notable cooldown from the mid-70s observed earlier in the weekend. Trader emphasis on the 62–65°F bins reflects tight model clustering around these values, with modest probabilities assigned to 66–67°F outcomes if skies clear earlier than forecast. Updated NWS briefings and hourly model runs over the next 48 hours will refine the precise maximum.

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 National Weather Service and model guidance point to a high of 64–65°F for Chicago on September 21, driven by a cooler northeast flow behind Saturday’s system and widespread cloud cover that limits daytime heating.
