Current National Weather Service forecasts and ensemble model guidance place Chicago’s August 31 high in the upper 80s to low 90s under southerly flow ahead of a warm front, with afternoon clearing and rising dew points supporting peak readings near 88–90 °F. This consensus underpins the near-even market split between the 88–89 °F and 90–91 °F bins. Key uncertainties include exact timing of warm-air advection, boundary-layer mixing depth, and any lingering morning cloud cover that could cap temperatures. Updated NWS point forecasts and next model cycles will refine these variables ahead of resolution.

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.
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.
