Current National Weather Service guidance and ensemble model consensus indicate a high near 84°F for Chicago on August 8 under mostly sunny skies with light south winds, supporting the near-even market split between 82–83°F and 84–85°F outcomes. Surface observations from Midway and O’Hare show morning temperatures in the upper 60s to low 70s amid moderate humidity, while short-range guidance highlights limited diurnal range due to weak steering flow and minimal cloud interference. Historical August normals near 83°F provide context, yet small shifts in boundary-layer mixing or afternoon timing of any weak front could tip the daily maximum by 1–2°F. Updated model runs and hourly observations through midday remain the key near-term drivers for trader positioning.

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 8 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.
