Recent National Weather Service and AccuWeather guidance points to a high in the upper 70s to low 80s for Chicago on August 21, consistent with the market’s heaviest weighting on the 78–81 °F bins. This positioning reflects a post-derecho pattern that has brought cooler, northeasterly flow and enhanced lake-breeze moderation from Lake Michigan, suppressing daytime maxima several degrees below the 82 °F climatological normal. Ensemble guidance shows limited diurnal heating under partly cloudy skies with only modest southwesterly return flow by afternoon. Model consensus remains tight around these values, though minor shifts in boundary-layer moisture or timing of any lake-breeze front could adjust the peak by 1–2 °F. Updated NWS short-range forecasts and morning sounding data tomorrow will provide the final inputs for 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 21 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 and AccuWeather guidance points to a high in the upper 70s to low 80s for Chicago on August 21, consistent with the market’s heaviest weighting on the 78–81 °F bins.
