Official National Weather Service observations for Denver on September 22, 2026, recorded a minimum temperature of 51°F shortly after dawn, placing the daily low firmly in the narrow 52-53°F band that commands 99.6% market-implied odds. This reading aligns with model guidance and surface observations showing limited overnight radiational cooling under partly cloudy skies and light winds, well above the 1991-2020 normal low of 48°F. Trader consensus reflects the finality of the verified climatological report, with only trace probability assigned to lower bins that would require an unreported station reading or post-hoc adjustment. A realistic challenge would need a revised official minimum below 52°F from the primary Denver station, an event historically rare once preliminary data are issued.

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 22 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.Official National Weather Service observations for Denver on September 22, 2026, recorded a minimum temperature of 51°F shortly after dawn, placing the daily low firmly in the narrow 52-53°F band that commands 99.6% market-implied odds.
