Recent National Weather Service guidance indicates highs near 76°F for Chicago on August 3 under persistent northeasterly flow and partial cloud cover that limits daytime heating below late-summer norms of 83–84°F. Ensemble model spreads introduce modest uncertainty around intensification of the onshore breeze or earlier clearing, supporting market-implied odds clustered at 78–81°F while keeping lower bins (76–77°F) viable. Surface observations and lake-modified air masses further temper peak readings, with any shift in steering patterns or reduced cloudiness the key variables that could tip resolution between the two leading temperature bins.

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 3 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.
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.Recent National Weather Service guidance indicates highs near 76°F for Chicago on August 3 under persistent northeasterly flow and partial cloud cover that limits daytime heating below late-summer norms of 83–84°F.
