Latest National Weather Service and ensemble model guidance positions an 80-81°F high as the most probable outcome for Chicago on August 18, reflecting near-normal August conditions tempered by moderating lake breezes and possible cloud cover or scattered showers that limit peak heating. Chicago’s proximity to Lake Michigan frequently generates onshore flow that suppresses afternoon temperatures below climatological normals around 82°F, while regional pressure patterns and dew point trends influence boundary-layer mixing and radiative heating. Official observations from Chicago O’Hare and Midway airports, along with updated short-range model runs, will determine the daily maximum used for market resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Chicago O'Hare Intl Airport Station, available here: https://www.wunderground.com/history/daily/us/il/chicago/KORD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
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.
