Forecast models from the National Weather Service and local outlets currently project a Denver low of 53–56°F on September 23, driven by mostly cloudy skies and light southerly flow that limits nocturnal radiative cooling. This places the outcome near the middle of the distribution, yet market-implied odds remain nearly even between 70°F or higher and 51°F or below because traders weigh residual uncertainty in cloud thickness, dewpoint depression, and any late-day shower activity that could alter the overnight minimum. Historical September averages near 46°F provide context, but the current warm bias stems from a stable high-pressure ridge holding through midweek. Updated model runs and NWS briefings on steering patterns and boundary-layer moisture will likely tighten the range ahead of resolution.

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 23 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.Forecast models from the National Weather Service and local outlets currently project a Denver low of 53–56°F on September 23, driven by mostly cloudy skies and light southerly flow that limits nocturnal radiative cooling.
