Recent National Weather Service forecasts and GFS model guidance point to a minimum temperature in the mid-60s Fahrenheit for Chicago on September 11, driven by clear skies, light southerly flow, and minimal overnight radiational cooling ahead of a gradual seasonal transition. Trader sentiment remains split near even odds between sub-52°F and 70°F-plus outcomes because ensemble spreads show potential for stronger northerly advection or cloud cover that could shift the low by several degrees. Historical climatology places the September 11 normal low near 61°F, providing context for how deviations in steering patterns or dewpoint profiles could resolve the market, with updated model runs and NWS briefings expected to narrow the range before resolution.

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.
