National Weather Service forecasts for Denver on August 21, 2026, call for a high near 99°F under mostly sunny skies with a 20% afternoon thunderstorm chance, directly supporting the tight market split between 96-97°F and 98-99°F outcomes. Strong solar heating under high pressure, combined with light winds and Denver's mile-high elevation reducing atmospheric thickness, favors peak readings in the upper 90s, while any early cloud build-up or scattered convection could cap the maximum slightly lower. Model consensus from recent runs shows minimal spread, with historical August norms around 87°F providing context for the above-average conditions. Updated NWS briefings and real-time observations near peak heating hours will offer the clearest signals for resolution.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Buckley Space Force Base Station in degrees Fahrenheit on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Buckley Space Force Base Station, available here: https://www.wunderground.com/history/daily/us/co/aurora/KBKF.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
