National Weather Service forecasts and major models including the GFS and ECMWF currently favor a Denver high of 78–81°F on May 16, driven by a strong upper-level ridge promoting subsidence, clear skies, and strong daytime heating from overnight lows near 55°F. Dry soils across the Front Range are enhancing surface warming well above the mid-May climatological normal of 73°F, with light south-southeast winds supporting peak readings in the late afternoon. This setup explains the tight clustering of market-implied probabilities around the 78–79°F and 80–81°F bins. An approaching weak shortwave trough adds modest uncertainty that could limit highs to the mid-70s, prompting traders to watch the next 00z model runs for any refinements before resolution.
