**Trader sentiment on Chicago's September 24 minimum temperature remains closely split between sub-48°F and 66°F+ outcomes because short-range forecast models show notable spread in expected overnight cooling.** Persistent northeast flow off Lake Michigan, combined with extensive cloud cover and dew points in the low-to-mid 50s, is limiting radiational cooling and keeping the thermal profile moderate. Current guidance from multiple sources points to a low in the mid-to-upper 50s, aligning with the September climatological average of 55°F, yet model runs differ on the exact strength of the onshore breeze and any breaks in cloudiness that could allow sharper drops. With resolution just 48 hours away, traders are weighting the potential for forecast revisions from the National Weather Service and updated model ensembles, as even modest shifts in wind or sky cover can swing the overnight minimum by several degrees. Historical records show September 24 lows ranging from the mid-30s to the low 70s, underscoring the genuine uncertainty at this lead time.

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 24 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.**Trader sentiment on Chicago's September 24 minimum temperature remains closely split between sub-48°F and 66°F+ outcomes because short-range forecast models show notable spread in expected overnight cooling.** Persistent northeast flow off Lake Michigan, combined with extensive cloud cover and dew points in the low-to-mid 50s, is limiting radiational cooling and keeping the thermal profile moderate.
