**National Weather Service forecasts for Denver on September 3 project a high near 93°F under mostly sunny skies with light southeast winds, positioning the 90-91°F and 92-93°F ranges as the dominant market-implied outcomes at 57% and 24% respectively.** These align with above-normal late-summer warmth, as the seasonal average high sits near 84°F, while model consensus and recent clear conditions support peak temperatures in the low-to-mid 90s. Minor forecast spreads across sources (87–93°F range) reflect typical uncertainties in afternoon heating rates, boundary-layer mixing, and exact wind shifts that can trim or boost the daily maximum by 1–2°F. Traders appear to weigh the official point forecast against historical variability and the resolution criteria tied to official station observations, with limited probability assigned to extremes outside the 88–95°F window given stable synoptic patterns. Updated NWS guidance and real-time temperature trends through peak heating hours will refine these implied probabilities.

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.
