National Weather Service and ensemble model guidance from the GFS and ECMWF currently converge on a Denver high near 78–80 °F for May 16, driven by a persistent upper-level ridge over the Four Corners region that favors strong subsidence, clear skies, and efficient daytime heating after overnight lows in the mid-50s. This pattern exceeds the mid-May climatological normal of 71–73 °F and supports the market’s tight clustering around the 78–81 °F buckets. Minor uncertainty stems from possible afternoon cirrus or isolated convective clouds that could trim insolation by a few degrees, while light southeasterly winds limit mixing; hourly readings at Denver International Airport will determine the precise peak before resolution tonight.
