Current forecasts from the National Weather Service and ensemble models indicate a low in the mid- to upper-50s°F for Seattle on August 28, consistent with the climatological average of 55.8°F. Overcast skies, light showers, and moderate marine airflow from the Pacific are expected to limit radiative cooling overnight while suppressing stronger temperature drops. Key variables include the timing of any clearing (which could enhance cooling under drier air) versus persistent cloud cover and wind mixing that moderates minima. Trader consensus centers on the 56–57°F bin as the most probable outcome, with elevated odds on 49°F or below reflecting model spread and tail risks from variable advection or humidity. Recent pattern shifts toward increased cloudiness have anchored probabilities near seasonal norms rather than extremes.
