Current forecasts from National Weather Service models and private sources project a Friday, August 28 overnight low for Chicago in the mid-60s Fahrenheit under mostly clear to partly cloudy skies with light southerly or variable winds. This consensus supports the market's tight clustering around 62–65°F outcomes, as radiative cooling overnight will be moderated by Lake Michigan's influence and typical late-August dew points. Minor model spreads arise from potential thin cloud cover or slight wind shifts that could raise or lower the minimum by 1–2°F, while historical averages near 65°F provide a stable baseline. No significant frontal systems or anomalous patterns are expected before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Chicago O'Hare Intl Airport Station in degrees Fahrenheit on 28 Aug '26.
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.Current forecasts from National Weather Service models and private sources project a Friday, August 28 overnight low for Chicago in the mid-60s Fahrenheit under mostly clear to partly cloudy skies with light southerly or variable winds.
