Forecast models from the National Weather Service and private sources project an overnight low near 54–56°F for Denver on September 14, driven by mostly cloudy skies, isolated thunderstorms, and light northwest winds under a moderating air mass following recent 80s–90s highs. This aligns with climatological norms of roughly 50°F average lows for the date while reflecting current steering patterns that limit rapid radiational cooling. Trader emphasis on the 59°F-or-below bin alongside the unrealistic 78°F-or-higher outcome highlights uncertainty around exact minimum thresholds, cloud-cover timing, and model spread in dew-point and wind forecasts. Upcoming NWS updates and real-time observations will clarify whether the low settles in the mid-50s or edges higher.

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.
