Persistent northeast winds and a stable cool air mass are anchoring Chicago temperatures in the mid-60s for September 23, aligning with National Weather Service forecasts of highs near 64–66°F. This pattern, featuring onshore flow from Lake Michigan and limited mixing, has suppressed readings several degrees below the late-September climatological average of roughly 73°F. Recent model runs show little day-to-day variability through midweek, with only modest afternoon warming possible if skies clear more than expected. Trader consensus therefore concentrates on the 64–65°F and 66–67°F bins, reflecting high confidence in official guidance while acknowledging minor uncertainty from cloud cover or wind shifts that could nudge the daily maximum by a degree or two.

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 23 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.Persistent northeast winds and a stable cool air mass are anchoring Chicago temperatures in the mid-60s for September 23, aligning with National Weather Service forecasts of highs near 64–66°F.
