**Current forecasts from the National Weather Service and other models indicate an overnight low in the mid-50s for Seattle on the night of August 28–29, positioning 54–55°F and 56–57°F as the leading market outcomes.** Persistent cloud cover, light winds, and scattered showers expected through the period limit radiative cooling, keeping temperatures from dropping sharply below seasonal norms. Seattle’s marine-influenced climate, with Pacific moderation, typically produces August overnight lows averaging near 56°F; recent model runs show only modest cooling under the cloudy, moist regime. The NWS explicitly forecasts a Saturday night low around 53°F, while other guidance clusters in the lower-to-mid 50s, aligning closely with the 43.5% and 33.5% market-implied probabilities for those two bins. No major shifts in steering patterns or stronger high pressure have emerged to alter this outlook, though final model updates before midnight local time could refine the exact minimum.
