**Official National Weather Service observations from Chicago O’Hare recorded a maximum temperature of 81°F on September 5, 2026, at 2:37 p.m. CDT, directly supporting the market’s 100% consensus on the 80–81°F bin.** This followed several days of abnormally high readings in the low-to-mid 90s driven by a warm, humid air mass, with the September 5 moderation resulting from a shift to northeast winds, increased cloud cover, and patchy fog that limited daytime heating. The value sits just 2°F above the 1991–2020 normal high of 79°F. Realistic challenges to this outcome remain minimal, as any revision would require an unlikely official data correction from NOAA or use of a non-standard station; traders’ skin-in-the-game alignment with verified measurements has produced near-certainty once the climatological report was released.

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.
