Recent National Weather Service and model guidance point to a moderating marine layer and increasing cloud cover over Puget Sound, holding the Seattle overnight low on August 28 near 55–58 °F. Light southerly to southwesterly winds and dew points in the low-to-mid 50s limit radiational cooling, while patchy showers and overcast conditions further reduce nighttime temperature drops compared with clearer prior nights. This places the 56–57 °F and 58–59 °F bins in close contention as traders weigh subtle differences in model timing of cloud arrival and wind strength. Historical August minima average near 56 °F, providing context for the narrow spread across leading outcomes. Updated forecast discussions expected later today could shift sentiment if model consensus tightens around a specific threshold.
