Recent National Weather Service and NOAA ensemble forecasts for Seattle indicate overnight minimum temperatures of 58–61°F on August 23, driven by a cooler maritime air mass and increasing cloud cover that limits radiational cooling over Puget Sound. This setup aligns with late-August climatology, where average lows hover near 57°F but can rise under weak onshore flow or residual moisture from scattered showers earlier in the period. Trader consensus in the 60–61°F bucket at 41% reflects the latest model runs favoring the upper end of the typical range, with secondary support for 58–59°F and 62–63°F as uncertainty in exact cloud timing and wind remains. Updated NWS guidance and next model cycles will refine these probabilities ahead of the daily minimum observation at Seattle-Tacoma International Airport.
