Recent National Weather Service forecasts and model consensus indicate a high of 89–91°F for Denver on September 7, 2026, under mostly cloudy skies with scattered thunderstorms possible, driven by a warm air mass and light easterly flow that limits afternoon mixing. This places the outcome firmly above the 1991–2020 climatological average high of 82.4°F for the date, consistent with the ongoing early-September warmth that has produced daily highs in the low-to-mid 90s. Ensemble guidance shows limited spread around these values, with any stronger instability or clearer skies as the main variables that could push readings into the low 90s. Updated model runs and NWS briefings over the next 48 hours will refine the final maximum before the market resolves.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Buckley Space Force Base Station in degrees Fahrenheit on 7 Sep '26.
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.Recent National Weather Service forecasts and model consensus indicate a high of 89–91°F for Denver on September 7, 2026, under mostly cloudy skies with scattered thunderstorms possible, driven by a warm air mass and light easterly flow that limits afternoon mixing.
