Recent National Weather Service guidance and ensemble model runs point to a Friday maximum near 83–87°F in Chicago, driven by an easterly wind shift off Lake Michigan that introduces cooler, more stable marine air and favors a pronounced lake breeze circulation. Morning cloud cover and a 30–50% chance of showers or thunderstorms—expected to clear by midday—further limit surface heating, while the lake’s thermal inertia typically caps shoreline readings several degrees below inland suburbs. This setup contrasts with the prior days’ 95–96°F readings under southwest flow, creating the observed market clustering around the upper 80s to low 90s as traders weigh model spread, exact observation site (O’Hare vs. Midway), and potential for delayed clearing or weaker onshore flow to push readings higher.

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 4 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 guidance and ensemble model runs point to a Friday maximum near 83–87°F in Chicago, driven by an easterly wind shift off Lake Michigan that introduces cooler, more stable marine air and favors a pronounced lake breeze circulation.
