Recent National Weather Service and model consensus forecasts a sunny Tuesday in Seattle with light southwesterly winds, favoring strong daytime radiative heating and modest warm-air advection that supports a maximum temperature near 84–85 °F. This places the outcome squarely between the two leading market bins (84–85 °F at 34.5 % and 82–83 °F at 33.5 %), where traders weigh the precise balance between clear-sky insolation, urban heat retention, and the moderating marine influence of Puget Sound. Southerly flow replacing earlier northerly winds has lifted guidance from the mid-70s observed on August 24, while low humidity and minimal cloud cover reduce the chance of significant cooling. Remaining uncertainty centers on exact wind timing and any late-day marine-layer return that could cap the peak a degree or two lower.
