Recent National Weather Service and private model runs project a high near 87–89°F in Denver on September 8, 2026, with partly cloudy skies and only isolated afternoon thunderstorms unlikely to suppress peak readings. This aligns with the market’s leading 88–89°F bin (41.5% implied probability) and the next tier at 86–87°F. Early-September climatology shows an 81.9°F average high, but a warm spell with daily maxima in the low-to-mid 90s through September 5 has kept temperatures elevated; steering flow and downslope warming continue to favor readings several degrees above normal. Updated guidance issued within the past 24 hours has remained stable, limiting upside risk to the 90–91°F tier (20.5%) and keeping lower outcomes below 20% combined. Traders are therefore pricing the narrow 86–89°F window as the most probable outcome ahead of final verification.

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.
