Forecast models and National Weather Service guidance point to a Denver high temperature in the low to mid-70s on September 20, driven by increasing cloud cover and scattered thunderstorm activity as a weak disturbance moves through the region. This setup limits surface heating compared to recent days in the upper 70s and low 80s, with northeasterly flow and higher humidity reducing diurnal temperature range. Key variables differentiating the closely bunched 70–71°F, 72–73°F, and 74–75°F outcomes include exact storm timing, cloud optical depth, and boundary-layer mixing depth, all of which remain sensitive to the latest model runs and observational updates through the weekend. Historical September variability in Front Range upslope moisture supports this modest cooling.

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.
