Official National Weather Service observations from Chicago-O'Hare, the primary reference station, recorded a maximum temperature of 87°F on August 31, 2026—well above the 80°F normal but below historical extremes like the 99°F record from 1953. A late-summer heat dome drove the warmth through southerly flow and elevated dew points, yet daytime showers, thunderstorms, and cloud cover limited further intensification. This aligns directly with the market-implied 86-87°F outcome at near-certainty. Resolution could shift only in the unlikely event of station-specific data revisions or alternative measurement protocols overriding the official report.

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 which 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 can not resolve until the first data point for the following date has been published on the resolution source.
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.
