National Weather Service forecasts and major model ensembles like GFS and ECMWF show strong consensus for Denver's high temperature on May 15 exceeding 80°F, well above the 74°F threshold, driving the 99.6% market-implied probability for 74°F or higher. This positioning stems from a robust upper-level ridge over the Rockies promoting mostly sunny skies, light winds, and adiabatic heating at Denver's elevation, following a dramatic pattern shift after the record-breaking May 5-6 snowstorm that dumped up to half a foot in the city. Trader sentiment reflects high-confidence model agreement with minimal precipitation odds under 10%. Realistic challenges include unexpected low-level moisture influx causing clouds or a faster-moving shortwave trough, though current guidance shows low risk; watch final NWS updates and morning soundings for any shifts.
