Recent National Weather Service forecasts and ensemble model runs point to mostly sunny conditions with light variable winds over Seattle on October 16, supporting afternoon highs in the low to mid-70s under a building high-pressure ridge. This setup favors gradual warming after overnight lows near 50°F, with minimal cloud cover limiting radiative cooling. Trader-implied odds cluster tightly around 72–77°F because short-range models show small spreads in peak timing and boundary-layer mixing, while historical October normals hover near 60°F. The next model cycle and morning observations will likely refine the exact maximum before resolution.
