National Weather Service forecasts and supporting model consensus indicate a high in the mid- to upper 70s for Seattle on August 24 under partly to mostly sunny conditions. This stems from an upper-level ridge building over the Pacific Northwest as an offshore low weakens, fostering northerly flow and subsidence that promotes warming and clear skies. Recent runs show tight clustering around 76–78°F with limited upside from localized effects, aligning trader sentiment with the 78–79°F bin at 43.5% implied probability, followed by 80–81°F and 76–77°F. Historical August norms near 75°F and the absence of strong marine influences further anchor these outcomes ahead of final observations.
