Northwesterly winds advecting cooler Canadian air masses, combined with Lake Michigan's thermal moderation, are the dominant factors anchoring Chicago's August 23 high in the mid-70s and driving the 58.5% implied probability on the 76-77°F bin. National Weather Service guidance currently projects a sunny high near 76°F under these conditions, with limited afternoon mixing keeping values below seasonal normals around 82°F. Recent model consensus shows minimal spread, though any late-day southerly shift or reduced cloud cover could push readings into the upper 70s. Official observations from O'Hare and Midway will resolve the market by evening, with traders weighting verified maximum temperatures over forecasts.

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 23 Aug '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
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Northwesterly winds advecting cooler Canadian air masses, combined with Lake Michigan's thermal moderation, are the dominant factors anchoring Chicago's August 23 high in the mid-70s and driving the 58.5% implied probability on the 76-77°F bin. National Weather Service guidance currently projects a sunny high near 76°F under these conditions, with limited afternoon mixing keeping values below seasonal normals around 82°F.
