Trader consensus on Polymarket reflects tight clustering around 78-81°F for Denver's May 16 high temperature, driven by National Weather Service guidance and major model ensembles like GFS and ECMWF projecting peaks near 80°F under a building upper-level ridge promoting subsidence and clear skies. This follows a sharp rebound from the major May 5-6 snowstorm that dumped up to 6 inches in Denver metro, with dry soils and light SSE winds now favoring efficient daytime heating at the city's 5,280-foot elevation. Differentiating factors include model spread—GFS runs slightly warmer at 80-81°F with minimal cloud interference, while ECMWF hints at cooler 78-79°F via diurnally developing cumulus fields or stray late-afternoon thunderstorms (20-55% precip odds). New 00Z model runs tonight and morning soundings will refine this uncertainty before peak heating Saturday afternoon.
