Latest National Weather Service forecasts and ensemble model runs indicate overnight lows for Chicago on August 27 will likely settle in the mid-60s under clearing skies and light northeast winds following daytime highs near 78°F. Radiational cooling overnight, moderated by Lake Michigan’s thermal influence, favors readings around 66–67°F at official stations like O’Hare, while slight variations in wind direction or cloud timing could shift the minimum into the 64–65°F or 62–63°F bins. Historical late-August averages near 65°F provide context, yet current guidance shows limited spread across GFS and ECMWF solutions, with any deviation hinging on precise dewpoint trends and boundary-layer mixing through the pre-dawn hours.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kord
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
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.
