Trader consensus on Polymarket assigns a 100% implied probability to a highest temperature of 66°F or higher in Denver on May 13 at Buckley Space Force Base, backed by National Weather Service forecasts projecting a peak near 90°F—the hottest day of 2026 so far and nearing the 1915 record of 90°F against a normal high of 70°F. This positioning stems from a robust upper-level ridge over the Rockies inducing subsidence, clear skies, and light winds, with morning readings already climbing past 60°F under mostly sunny conditions; major models like GFS and ECMWF show tight agreement on upper-80s to low-90s peaks. Realistic challenges include unexpected afternoon thunderstorms or marine layer influx capping heating, though current guidance pegs precipitation odds below 20%, with intraday observations determining final resolution.
