**National Weather Service forecasts for Seattle on August 10 center on a high near 77°F under mostly sunny skies, consistent with the tight market clustering around 76–79°F.** Recent days brought slightly warmer readings in the low 80s amid stronger high pressure, but a modest onshore flow and increasing marine influence are expected to moderate afternoon heating. Key variables separating the leading bins include the precise timing of any morning cloud cover, wind speeds that enhance or limit mixing, and small differences among model runs for boundary-layer moisture. Historical August averages near 76–78°F provide context, while the absence of strong offshore winds or clear-sky amplification keeps probabilities for 80°F+ relatively low. Updated NWS and model guidance over the next 24 hours will likely refine the exact peak before resolution.
