National Weather Service guidance and short-range forecast models indicate a high temperature in Chicago on September 18 in the low to mid-70s, driven by easterly flow, extensive cloud cover, and limited daytime heating following recent frontal activity. This setup favors 72-73°F as the leading resolution range, consistent with observed trends and climatological norms for mid-September under similar synoptic patterns. Market-implied probabilities align closely with this consensus, with 70-71°F and 74-75°F as secondary outcomes reflecting minor model spread and potential for slight warming if skies clear earlier than expected. Updated NWS briefings and afternoon observations will provide the final verification data for 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 18 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.National Weather Service guidance and short-range forecast models indicate a high temperature in Chicago on September 18 in the low to mid-70s, driven by easterly flow, extensive cloud cover, and limited daytime heating following recent frontal activity.
