Current National Weather Service and ensemble model guidance points to a September 7 high in Chicago of 77–82 °F, aligning with the market’s leading 78–81 °F bin at 36.5 % implied probability. Northeast flow off Lake Michigan is expected to moderate peak readings near the lakefront while allowing slightly warmer conditions inland, keeping values close to the 1991–2020 normal of 79 °F. Limited model spread and stable synoptic pattern support the tight clustering around 76–81 °F, yet the two-day forecast horizon leaves room for minor shifts in cloud cover or wind direction that could alter the daily maximum by a degree or two before official observations finalize at O’Hare.

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.
