Trader sentiment for Seattle's August 2 high temperature centers on National Weather Service forecasts showing a moderate range driven by persistent marine air and a weak upper-level trough. Onshore southwesterly flow and increasing clouds are limiting daytime heating, keeping projected maxima near 70–73°F at Sea-Tac, consistent with the market's clustered probabilities around those bins. This setup aligns with climatological norms for early August under neutral ENSO conditions, where sea-surface temperatures near 55–58°F offshore moderate extremes. Key uncertainties include the exact timing of any clearing or wind shifts that could add or subtract a few degrees, with model consensus narrow enough to explain the tight spread among 68–73°F outcomes rather than higher readings seen in hotter summer patterns. Updated NWS briefings and afternoon model runs will provide the next resolution signals.
