Recent National Weather Service and NOAA guidance for Denver points to an overnight low near 60°F on September 8 amid isolated thunderstorms that could limit radiational cooling under partly cloudy skies and light winds. Model consensus favors this range, yet small shifts in cloud cover, dew points, or frontal timing can alter minimum temperatures by several degrees, producing the tight spread across 60–65°F and warmer outlier bins. Historical September climatology shows typical lows in the low 50s, but the current warmer pattern supports the market-implied clustering around 60–63°F while leaving room for higher readings if mixing persists. Updated model runs and evening observations will refine the outlook ahead of resolution.

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=kbkf
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.
