Persistent cloud cover and a steady northeast wind flow are positioning the overnight low in Chicago near 56–60°F on September 21, limiting radiational cooling while advecting cooler air from the Great Lakes region. National Weather Service guidance and ensemble model runs show the minimum occurring under overcast skies with light precipitation tapering overnight, keeping temperatures from dropping into the lower 50s despite the seasonal climatological average low near 56°F. Recent upstream observations confirm this pattern has held through the past 48 hours, with minimal model spread supporting the 56–60°F range as the most probable outcome and explaining the market’s concentration on the 56–61°F bins.

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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
