Recent National Weather Service forecasts and ensemble model runs point to a daily minimum near 58–60 °F for Denver on September 11 under partly cloudy skies and light southerly flow. Clear nocturnal conditions would enhance radiative cooling and favor readings at or below 53 °F, while increased cloud cover, stronger winds, or downslope warming could hold the low above 72 °F. Historical September climatology shows an average minimum of 51 °F, yet the current warm, dry high-pressure ridge has kept recent overnight lows in the upper 50s. Traders appear to weigh these competing factors—model consensus on mild conditions versus potential for rapid radiative drops or advection shifts—producing the near-even split between the extreme outcomes. Updated model guidance and local observations in the next 48 hours will likely refine the implied probabilities.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Buckley Space Force Base Station in degrees Fahrenheit on 11 Sep '26.
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.Recent National Weather Service forecasts and ensemble model runs point to a daily minimum near 58–60 °F for Denver on September 11 under partly cloudy skies and light southerly flow.
