Recent National Weather Service and model guidance for Chicago on August 31 shows a warm southwesterly flow advecting a moist air mass, supporting daytime highs in the upper 80s to low 90s under partly to mostly cloudy skies. This positions the 90-91°F bin as the market favorite at 35% implied probability, followed closely by 88-89°F, as variable cloud cover and any light shower timing could trim peak solar heating by 1-3°F. Ensemble spreads from GFS and ECMWF runs reflect this narrow range, with urban heat island effects and typical late-summer humidity providing a modest boost over rural baselines. Traders are watching the next NWS forecast updates and afternoon model runs through August 30 for any shift in cloud or wind trends ahead of 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 31 Aug '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.
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.
