**High pressure building over the Pacific Northwest is supporting mostly sunny skies and above-average warmth for Seattle on October 3, with National Weather Service forecasts calling for a high near 68°F.** This stems from offshore flow and subsidence that limits cloud cover and enhances daytime heating, though morning marine influence and light northerly winds may cap the peak. Latest model guidance and NWS point forecasts cluster in the mid-to-upper 60s, several degrees above the 1991–2020 climatological average high of 64.7°F for the date, while still well below record territory near 80°F. Trader sentiment remains split across the 68–75°F bins due to typical short-range forecast spread in boundary-layer mixing and exact wind timing, with new NWS updates and model runs expected to refine the outcome before resolution.
