Latest National Weather Service and local forecasts position the 76-79°F range as the clear market leader for Denver’s September 19 high, reflecting model consensus on a seasonal-average peak near 77–79°F amid scattered afternoon thunderstorms. These conditions, driven by moderating northeast flow and increased cloud cover, limit daytime heating compared with the prior week’s warmer readings. Historical climatology shows a 77.8°F average high for the date, providing additional context for trader positioning. Updated model runs and any shifts in storm timing or intensity ahead of the 24-hour verification window remain the key variables that could nudge probabilities within the narrow 76–81°F band.

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 19 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.Latest National Weather Service and local forecasts position the 76-79°F range as the clear market leader for Denver’s September 19 high, reflecting model consensus on a seasonal-average peak near 77–79°F amid scattered afternoon thunderstorms.
