Recent National Weather Service and model guidance indicate a cooling trend for the Pacific Northwest, with scattered showers and onshore flow expected to moderate temperatures in Seattle on August 22, 2026. This follows a warmer-than-average summer driven by persistent ridging, now giving way to a Pacific front that favors marine air intrusion and cloud cover limiting daytime heating. Official forecasts cluster daily highs near 72–75°F, consistent with climatological late-August norms around 75°F but tempered by the approaching disturbance. Trader consensus heavily weights the 70–73°F range because these align with ensemble outputs showing limited instability and marine-layer influence, while higher bins reflect only slim upside risk if the front stalls. Upcoming NWS updates and morning model runs will refine landfall timing and cloud cover, the key variables that could shift implied probabilities before resolution.
