National Weather Service forecasts from Boulder project Denver's high temperature on April 13 reaching 70-77°F under a persistent upper-level ridge promoting subsidence warming and southwesterly downslope winds, aligning with GFS and ECMWF model consensus after record 86°F heat Saturday—the earliest such mark in 153 years of observations. Morning readings already in the mid-50s°F with clear skies reinforce this trajectory, well above the 61°F climatological normal, driving trader sentiment to a 98.3% implied probability for 64°F or higher. Realistic challenges include unanticipated cloud development or an accelerated cold front, though low-probability given current steering patterns; monitor hourly updates from Denver International Airport observations for final resolution.
