Latest National Weather Service and model guidance for Seattle-Tacoma International Airport points to a daily high near 78°F on July 19, reflecting moderate onshore flow from the Pacific and a stable marine layer that limits daytime warming in the Puget Sound region. Ensemble forecasts cluster most likely outcomes between 76–81°F, consistent with climatological July averages around 78°F and the absence of strong high-pressure ridging or offshore winds that could push temperatures higher. Recent model runs show minor spread due to subtle variations in cloud cover and boundary-layer moisture, keeping the 78–79°F bracket as the market leader while assigning meaningful probability to adjacent ranges. Updated NWS briefings and afternoon model releases tomorrow morning will provide the final inputs before resolution.
