Current National Weather Service and model guidance point to persistent warm advection under southwest flow, sustaining mid-70s overnight lows for Chicago on September 3 amid late-season heat and humidity, with scattered thunderstorms offering limited nocturnal cooling. This setup supports market-implied odds clustering in the mid-70s to low-80s while the 35% probability on 67°F or below captures residual uncertainty from potential model shifts, convective outflows, or a faster frontal passage. Historical September 3 averages near 63°F underscore how anomalous the current pattern remains, and traders weigh upcoming forecast updates against climatological baselines when assessing resolution thresholds.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
