Current forecasts from NWS-aligned sources place Denver's September 22 low in the low-to-mid 50s°F, aligning with the market's tight clustering around 48–55°F bins. Seasonal transition into fall reduces daytime heating while clear to partly cloudy skies overnight promote radiational cooling under light winds and low humidity typical of the Front Range. Scattered thunderstorm chances on the 22nd introduce the main uncertainty, as increased cloud cover could limit overnight temperature drops by several degrees compared to clearer scenarios. Model consensus and historical late-September diurnal ranges support this narrow band, with traders weighting the balance between potential intensification of cooling versus any moisture or wind shifts that could raise the minimum.

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.Current forecasts from NWS-aligned sources place Denver's September 22 low in the low-to-mid 50s°F, aligning with the market's tight clustering around 48–55°F bins.
