Trader sentiment for Denver's March 25 high temperature clusters tightly around 80-89°F bins at 17% implied odds each, driven primarily by the latest NOAA Global Forecast System (GFS) and ECMWF ensemble models projecting peaks in the mid-to-upper 80s under a persistent high-pressure ridge over the central Rockies. This setup favors adiabatic warming from downslope chinook-like winds, with clear skies and low soil moisture amplifying temperatures well above the 57°F climatological average. Differentiation among leaders hinges on frontal boundary timing—earlier passage caps at 80-83°F (17%), while delays push toward 86-89°F (17%) per 00Z runs. Historical late-March outliers, like 2012's 81°F, support upside risk, though 2.5% odds below 77°F reflect minimal trough intrusion probability.
