Recent National Weather Service and local model guidance point to an overnight low near 52°F in Denver on September 21, aligning with the market’s leading 52-53°F bin. Partly cloudy skies and light easterly winds are expected to limit radiative cooling while a moderating air mass keeps minimums in the low 50s, consistent with recent daily lows of 49–55°F. Key variables include cloud cover thickness, which reduces heat loss, surface wind speeds that enhance mixing, and any late-day showers that could raise dew points. Updated NWS forecast discussions and evening model runs will refine these thresholds 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 21 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 and local model guidance point to an overnight low near 52°F in Denver on September 21, aligning with the market’s leading 52-53°F bin.
