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 20 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Buckley Space Force Base Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket overwhelmingly favors a high temperature of 40°F or higher in Denver on April 20 (99.5% implied probability), driven by the latest National Weather Service forecasts projecting sunny skies and daytime highs near 73–79°F at Denver International Airport, the market's resolution site. This positioning reflects model consensus from NOAA's short-range guidance, showing a high-pressure ridge building over the Rockies after recent snow showers on April 17–18 cleared out, enabling strong solar heating at Denver's 5,000-foot elevation amid light southwest winds. Historical April 20 highs average 60°F, with rare dips below 40°F requiring freak cold outbreaks. Realistic challenges include an unexpected late-season front or persistent cloud cover delaying warmup, though current ensemble models show minimal spread and high confidence through the next update.
