Recent National Weather Service and AccuWeather guidance points to a highest temperature in the upper 70s to low 80s for Chicago on August 20, aligning with the market's emphasis on the 78–79°F bin. Seasonal normals near 82°F are tempered by persistent post-derecho moisture, variable cloud cover, and potential lake-breeze moderation from Lake Michigan, which can suppress afternoon highs by several degrees in urban areas. Model consensus currently favors limited warming under partly sunny conditions, though any reduction in onshore flow or clearing skies could push readings toward the 80–81°F range. Traders are monitoring the next NWS forecast updates and short-range model runs for shifts in boundary-layer moisture and wind patterns 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 20 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.
