Recent National Weather Service and local forecast guidance for Denver on August 19 point to a high in the upper 80s to low 90s, driving the market's strong preference for the 88–91°F range as the consensus outcome. This aligns with climatological normals near 87°F for the date and a warm late-summer pattern persisting after earlier August heat records, though increasing afternoon thunderstorm chances and potential cloud cover introduce modest cooling risks. Model runs show limited spread, with traders weighting official observations from Denver International Airport and surface conditions heavily. Final forecast adjustments from the NWS Boulder office and updated model guidance ahead of the period will likely determine whether probabilities shift toward the 90–91°F bin or hold near the current implied odds.

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 19 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.
