Recent National Weather Service guidance points to a high in the upper 80s for Chicago on September 4, with the market favoring 86–87 °F as the most likely peak amid a humid airmass following several days above 90 °F. Lake Michigan’s moderating influence is expected to keep shoreline readings several degrees cooler than inland sites, while increasing easterly flow and a 40–50 % chance of morning showers or thunderstorms could reduce afternoon insolation and cap maximum temperatures. Ensemble model consensus shows limited spread around this range, though subtle differences in cloud cover timing or lake-breeze strength could shift the daily high by 2–4 °F. Updated short-range model runs and National Weather Service briefings in the next 48 hours will provide the clearest signals ahead of market resolution.

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 4 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 guidance points to a high in the upper 80s for Chicago on September 4, with the market favoring 86–87 °F as the most likely peak amid a humid airmass following several days above 90 °F.
