Recent National Weather Service and ensemble model guidance points to overnight lows in the low-to-mid 60s for Chicago on September 19, with persistent cloud cover, widespread showers and thunderstorms, and southerly flow limiting radiative cooling. These conditions support the market's heaviest positioning on the 62-63 °F and 64-65 °F bins. The system’s arrival has already raised minimum temperatures several degrees above the late-September climatological average of 57 °F, while steering patterns and high dew points reduce the chance of a sharper drop. Updated model runs tonight and early-morning observations will be the next key inputs before the daily minimum is recorded.

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.
