**Recent forecasts from NOAA-affiliated and private meteorological sources consistently point to an overnight low near 60°F for Seattle on the night of August 25–26, 2026, supporting the market’s heavy weighting toward the 58–59°F bucket (71% implied probability).** Persistent southerly flow and partial cloud cover associated with a lingering upper-level ridge have limited radiational cooling, keeping temperatures from dropping to the long-term August average low of 56°F. Model guidance and current observations show the temperature bottoming in the upper 50s to low 60s under mostly clear to partly cloudy skies with light southwesterly winds, aligning with the 56–57°F (24.5%) and 60–61°F (20.5%) outcomes also seeing notable trader interest. These conditions reflect a warmer-than-climatology pattern driven by offshore flow earlier in the week that moderated overnight minima, with little indication of stronger cooling before sunrise on the 26th. Upcoming official observations from Seattle-Tacoma International Airport and local stations will determine the final recorded low for market resolution.
