National Weather Service observations and verification data from Denver’s official reporting station confirm a daytime high of 76–77°F on May 16, 2026, under a stable high-pressure ridge with light northerly flow that limited afternoon warming. Consensus runs from the GFS and ECMWF models, initialized 24–48 hours earlier, consistently projected peak temperatures in this narrow range after accounting for Denver’s high-elevation diurnal cycle and typical May climatology near 74°F. With the event now complete and official readings aligned precisely with those forecasts, trader consensus has converged on the 76–77°F outcome at essentially 100 percent implied probability. Only an unreported station anomaly or post-event data revision could alter resolution, scenarios considered highly unlikely given standard NOAA quality-control protocols.
