Recent ensemble forecasts from the National Weather Service and major models indicate Chicago's August 17 high temperature will likely fall in the upper 70s to low 80s, driven by post-derecho stabilization, northerly flow off Lake Michigan, and variable afternoon cloud cover that caps peak heating. Lake moderation and lingering moisture from mid-August storms create tight clustering between 78–81°F outcomes, with small shifts in timing or insolation able to tip the maximum by 1–2°F. Trader consensus reflects this narrow uncertainty band ahead of final observational data.

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 17 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.
