Latest National Weather Service forecasts and ensemble model guidance indicate sunny, stable conditions over Seattle for August 7, with daytime highs centered in the mid-80s, driving the near-even market-implied odds between the 84–85°F and 86–87°F bins. Persistent high pressure and light northwest flow are expected to limit marine influence and cloud cover, supporting modest warming above the long-term August average high of roughly 77–79°F at Sea-Tac. Minor spread among short-range models reflects typical uncertainty in boundary-layer mixing and any residual smoke effects, while the overall pattern aligns with the broader 2026 summer signal of above-normal temperatures across the Pacific Northwest. The market will resolve on the official highest temperature recorded at Seattle-Tacoma International Airport.
