Recent National Weather Service forecasts and model runs point to a moderating airmass with northerly flow and periods of clouds and showers limiting daytime heating for Chicago on September 17, keeping the daily maximum most likely in the mid- to upper-70s. Early September warmth from a persistent high-pressure ridge has given way to cooler Canadian air and increased moisture, with historical averages near 76°F providing context for the current setup. Key variables separating the tightly bunched 74–79°F outcomes include the precise timing of any afternoon clearing, Lake Michigan breeze strength, and minor differences among ensemble members regarding boundary-layer mixing and solar insolation. Updated model guidance and NWS briefings over the next 48 hours will refine these details ahead of market 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 17 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.Recent National Weather Service forecasts and model runs point to a moderating airmass with northerly flow and periods of clouds and showers limiting daytime heating for Chicago on September 17, keeping the daily maximum most likely in the mid- to upper-70s.
