Recent National Weather Service and ensemble forecasts position Chicago’s August 28 high near 79–82 °F under mostly sunny skies and light easterly flow, with the official O’Hare reading likely tempered by Lake Michigan’s moderating influence. This places the 82–83 °F bin as the market favorite at 58 percent implied probability, consistent with climatological norms (historical average high 81 °F) and the absence of strong warm advection or clear-air subsidence that would push readings into the mid-80s. Model consensus shows only modest spread, limiting upside risk to the 5 percent chance assigned to 86–87 °F, while cooler lake-adjacent zones support the 18.5 percent weighting on 80–81 °F. Updated guidance later today will refine the exact maximum before 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 28 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
