Recent National Weather Service guidance points to a Tuesday high near 77°F in Seattle under decreasing clouds and light variable winds, reflecting typical late-summer moderation from the marine layer over Puget Sound. This follows a brief early-August warming spell that produced highs in the low-to-mid 80s before a gradual cool-down, consistent with climatological norms where August averages hover around 77°F. Model consensus and ensemble spreads favor upper-70s readings with limited upside from reduced onshore flow, aligning with market-implied probabilities that cluster around 78–81°F while assigning low odds to extremes above 82°F or below 76°F. Updated short-range guidance and boundary-layer observations will refine these probabilities ahead of resolution.
