Official National Weather Service observations from Chicago O'Hare recorded a daily maximum of 83°F at 2:32 PM CDT on August 28, 2026, aligning precisely with the market's dominant 82-83°F outcome. This reading sat just 2°F above the 1991-2020 normal high of 81°F under mostly sunny skies and light southerly flow, with no late-day convective activity or lake-breeze cooling to suppress the peak. Preceding forecasts consistently projected lower-80s highs, and the climatological report issued at 4:33 PM confirmed the value before sunset. While minor station-to-station variations or final quality-control adjustments remain theoretically possible, the official maximum has already been observed and documented, leaving negligible scope for outcomes outside the narrow 82-83°F band.

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.
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.Official National Weather Service observations from Chicago O'Hare recorded a daily maximum of 83°F at 2:32 PM CDT on August 28, 2026, aligning precisely with the market's dominant 82-83°F outcome.
