Official forecasts from the National Weather Service and local outlets project a high near 84°F for Denver on September 12 under mostly sunny to fair skies with light winds and minimal precipitation chances. This aligns with the market's leading 84-85°F bin, reflecting trader weighting of model consensus around radiative daytime heating at high elevation amid dry late-summer air masses. Recent warmer days (highs in the low 90s) have given way to modest cooling from increased cloud cover and easterly flow, narrowing the range while historical averages near 80°F provide baseline context. Minor model spreads in afternoon mixing and boundary-layer moisture sustain probability across adjacent bins, with resolution hinging on the official daily maximum recorded at Denver International Airport.

The resolution source for this market will be information from NOAA, specifically the highest 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.
