Recent National Weather Service forecasts and local model consensus for Seattle on August 21 point to a high near 79–81°F under weak ridging and moderate onshore flow from the Pacific, anchoring trader sentiment around the 80–83°F range. This setup limits afternoon heating compared to typical August peaks near 79°F, with the marine layer and light northwest winds moderating temperatures. El Niño strengthening in the tropical Pacific contributes to broader warmer baseline conditions across the Northwest but shows limited direct influence on this short-term pattern. Key upcoming data include the next NWS model runs and afternoon updates, which could shift probabilities if instability or clearer skies develop.
