Official National Weather Service forecasts for Chicago on September 14 project a high near 72°F under mostly sunny skies following today's showers, with southeast winds and minimal cloud cover limiting additional warming. This positions the 72-73°F outcome as the market leader at 59.5% implied probability, consistent with model consensus and post-frontal cooling in the current air mass. Nearby bins at 70-71°F and 74-75°F capture residual uncertainty in exact peak timing and microscale variations, while higher or lower extremes remain low-probability given stable steering patterns and absence of significant warm advection. Traders are monitoring any late-model updates or observational shifts before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 14 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Official National Weather Service forecasts for Chicago on September 14 project a high near 72°F under mostly sunny skies following today's showers, with southeast winds and minimal cloud cover limiting additional warming.
