**Persistent warm, humid air under southwest flow is supporting overnight lows in the mid-70s for Chicago on August 31.** Official National Weather Service guidance and multiple forecast models show partly cloudy to partly sunny conditions with continued southerly winds, limiting radiational cooling and keeping minimum temperatures elevated well above the late-August climatological average of ~64°F. Dew points in the mid-to-upper 60s combined with the warm advection from a passing warm front have produced the current consensus around 74–77°F. Traders are weighting the tightly bunched 74–77°F outcomes most heavily because ensemble spreads remain modest and no significant frontal passage or increased cloud cover is expected to alter the thermal profile before resolution. Historical precedent for such warm August lows is limited, reinforcing the market’s focus on the narrow range implied by current model agreement.

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 31 Aug '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.
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.**Persistent warm, humid air under southwest flow is supporting overnight lows in the mid-70s for Chicago on August 31.** Official National Weather Service guidance and multiple forecast models show partly cloudy to partly sunny conditions with continued southerly winds, limiting radiational cooling and keeping minimum temperatures elevated well above the late-August climatological average of ~64°F.
