Current National Weather Service-aligned forecasts indicate a high near 87°F for Chicago on September 4, 2026, following a hot spell with mid-90s readings on September 2. Moderating easterly winds off Lake Michigan, combined with 40-50% chances of morning showers and thunderstorms, are expected to cap daytime heating through reduced solar insolation and increased cloud cover. These factors create tight clustering in market-implied odds around 86-91°F, as small shifts in storm timing, lake-breeze strength, or boundary-layer mixing could differentiate outcomes within that narrow range. Historical September 4 averages near 80°F underscore the elevated but uncertain warmth relative to climatology.

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 4 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.Current National Weather Service-aligned forecasts indicate a high near 87°F for Chicago on September 4, 2026, following a hot spell with mid-90s readings on September 2.
