Forecasts from the National Weather Service and supporting model runs indicate a minimum temperature in the mid-60s for Chicago on September 11, driven by clear to partly cloudy skies overnight that promote radiational cooling under light easterly flow. This setup favors readings near 63–66°F at O’Hare and Midway, consistent with climatological September lows around 61°F but tempered by recent above-normal warmth and southerly moisture advection. Ensemble spread in guidance creates balanced trader positioning across the 62–63°F, 60–61°F, and adjacent bins, while the low probability assigned to 51°F or below reflects the absence of strong cold-air advection or frontal passage. Updated NWS briefings and next model cycles will refine the exact threshold before overnight observations finalize the market.

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.
