Recent National Weather Service and local forecasts indicate a Sunday overnight low near 63°F for Denver amid scattered thunderstorms, with highs around 91°F under partly to mostly cloudy skies that could limit radiational cooling. This aligns with the market's tight clustering around 62-65°F buckets while the elevated share for 57°F or below captures residual model spread on shower timing, wind, and cloud cover. Warmer-than-average early September conditions, driven by persistent southerly flow and above-normal dew points, have kept overnight minima several degrees above the 1991-2020 climatological low of 53°F, creating the current balance in trader-implied probabilities ahead of final observational data.

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.
