Recent National Weather Service and ensemble model guidance for Chicago points to a daytime high in the upper 70s to low 80s on August 19, with trader probabilities clustered tightly on the 78–81°F bins. Persistent cloud cover and residual moisture from upstream systems are limiting solar insolation and capping afternoon temperatures below the 82°F seasonal normal. Small differences in forecast high hinge on the precise timing of any scattered showers, boundary-layer mixing depth, and the degree of clearing behind a weak frontal passage. These variables create genuine uncertainty across adjacent temperature bins, keeping market-implied odds closely matched as traders weigh the latest model runs ahead of 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 19 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.
