Forecast models from the National Weather Service and local stations indicate a September 5 overnight low in Denver near 62–64°F under partly cloudy skies, light northerly winds around 10 mph, and moderate humidity near 30–40%. These conditions limit radiative cooling compared with clear, calm nights that favor sharper drops toward the seasonal average of 54°F. Trader consensus clusters around 57°F or below and the mid-60s because small shifts in cloud timing or wind speed can alter minimum temperatures by 3–5°F, while the urban heat island effect and elevation keep extremes below 58°F or above 70°F unlikely. Updated model runs overnight and early-morning observations will refine resolution thresholds before the daily minimum is finalized.

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.
