Recent National Weather Service and local model consensus points to a clear, sunny Saturday with Denver's overnight low settling in the mid-50s, driven by high pressure, light winds, and efficient radiative cooling under dry September conditions at 5,280 feet elevation. This setup typically produces 5–10°F of nocturnal temperature drop after daytime highs near 84°F, with minimal cloud cover or moisture to retain heat. Traders' near-even split between sub-45°F and 64°F+ outcomes reflects short-term forecast sensitivity to any late model shifts in wind or humidity, though current guidance shows little divergence and aligns with climatological norms for late-September Denver nights. Final resolution will hinge on official observations once the calendar day closes.

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.
