Current National Weather Service and local forecasts for Denver on September 11 project an overnight low of 58–61°F under partly cloudy skies and light variable winds, driven by a stable high-pressure ridge promoting clear radiative cooling overnight. This places the daily minimum in the upper 50s to low 60s, consistent with recent warm anomalies where daytime highs have reached the low 90s and prior nights have bottomed in the upper 50s. Key variables differentiating narrower bins include exact cloud timing, which can trap heat and raise the minimum by several degrees, versus clearer conditions enhancing cooling toward 55°F or below. Historical September normals near 51°F underscore the current elevated baseline, while model consensus remains tight absent incoming fronts.

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.
