**Current forecasts from the National Weather Service and private models indicate overnight lows in the low-to-mid 70s for Chicago on September 4, driven by a lingering warm, humid air mass with dew points near 70°F that limits radiational cooling.** Persistent southwesterly flow, possible evening thunderstorms, and partial cloud cover further suppress temperature drops, while Lake Michigan’s moderating influence keeps lakeside readings from falling as sharply as inland areas. Historical September 4 lows average around 63°F, making the projected values well above normal and explaining trader emphasis on bins above 70°F. Model consensus remains tight on minimal overnight cooling, though slight variations in storm timing or wind shifts could nudge the official low a degree or two in either direction before the 24-hour observation window closes.

This market will resolve to the temperature range that contains the lowest 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 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.**Current forecasts from the National Weather Service and private models indicate overnight lows in the low-to-mid 70s for Chicago on September 4, driven by a lingering warm, humid air mass with dew points near 70°F that limits radiational cooling.** Persistent southwesterly flow, possible evening thunderstorms, and partial cloud cover further suppress temperature drops, while Lake Michigan’s moderating influence keeps lakeside readings from falling as sharply as inland areas.
