Current NWS and ensemble model guidance points to overnight radiative cooling under partly to mostly cloudy skies with light southwest winds, producing a minimum temperature in Denver on August 29 most likely between 60–65 °F. This range aligns with market-implied probabilities clustered around the 64–67 °F bins, reflecting trader assessment of limited nocturnal mixing and the moderating influence of residual moisture from afternoon thunderstorm chances. Late-August climatology shows an average low near 55.5 °F, yet the current warmer pattern—driven by a persistent upper-level ridge—has kept recent overnight minima several degrees above normal. Key variables differentiating the closely matched outcomes include exact cloud-cover timing, any shower-induced temperature resets, and the urban heat-island effect at official reporting stations. Updated model runs and the next NWS forecast discussion will provide the primary near-term catalysts for shifts in these probabilities.

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.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
