Current forecasts from the National Weather Service and models like those referenced by WeatherBug indicate a Thursday high near 88°F for Chicago, with scattered thunderstorms possible amid partly cloudy skies and southwest flow. This setup, following hotter 90s readings earlier in the week, supports trader consensus around the 86–89°F range as the leading outcomes. Lake-breeze effects could cap temperatures in the lower 80s near the shoreline while inland areas reach the upper 80s, and storm timing introduces uncertainty in peak readings. Historical September averages near 80°F provide context, but short-term model consensus and moisture levels differentiate the closely matched probabilities more than longer-term trends. Updated NWS briefings and afternoon observations ahead of resolution will likely refine these odds.

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 3 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 forecasts from the National Weather Service and models like those referenced by WeatherBug indicate a Thursday high near 88°F for Chicago, with scattered thunderstorms possible amid partly cloudy skies and southwest flow.
