Official forecasts from the National Weather Service and local outlets project a high near 93°F in Denver on September 4 under mostly sunny skies with light winds and minimal precipitation chances around 20%. This exceeds the 1991–2020 daily average high of 83.6°F, driven by persistent high pressure and southerly flow typical for early September. Model consensus supports a peak in the low 90s, with limited spread across runs, aligning with the market-implied 55.5% probability on 92–93°F and 25% on 94–95°F. Traders appear to weigh the strong forecast agreement against minor uncertainties in afternoon heating or boundary-layer mixing that could nudge readings slightly higher or lower. Updated NWS guidance remains the key near-term catalyst.

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.
