Official National Weather Service and NOAA forecasts for Chicago O'Hare on September 6, 2026, project a daily high in the upper 70s amid northeast to east winds of 5-10 mph, increasing cloud cover through the afternoon, and a stable post-heatwave air mass. These conditions limit surface heating compared to the prior week's 90-plus readings, aligning with climatological norms near 79-80°F for early September. Market-implied odds heavily favor 78-79°F or 76-77°F bins, reflecting trader assessment of model consensus on modest daytime maxima without significant warm advection or clearing skies. Updated runs show low precipitation risk and steady dew points supporting this narrow range, with resolution hinging on the official 24-hour maximum observation.

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 6 Sep '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.
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.Official National Weather Service and NOAA forecasts for Chicago O'Hare on September 6, 2026, project a daily high in the upper 70s amid northeast to east winds of 5-10 mph, increasing cloud cover through the afternoon, and a stable post-heatwave air mass.
