Persistent northeast winds and extensive cloud cover from a lingering weather system are suppressing daytime heating in Chicago, with National Weather Service forecasts calling for a Monday high near 64°F and only a slight shower chance. This aligns with recent observations of mid-60s readings under similar breezy, overcast conditions, well below the late-September climatological average of roughly 74°F. Model consensus shows minimal additional warming potential before peak afternoon temperatures, positioning the 64-65°F outcome as the market leader while the 66-67°F bin reflects residual uncertainty in exact peak timing or localized heating. Updated NWS guidance and hourly temperature trends ahead of resolution will be the key near-term drivers.

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.Persistent northeast winds and extensive cloud cover from a lingering weather system are suppressing daytime heating in Chicago, with National Weather Service forecasts calling for a Monday high near 64°F and only a slight shower chance.
