Latest National Weather Service guidance and ensemble models point to a peak temperature near 72°F at Seattle-Tacoma International Airport today, driven by clear skies, light northerly flow, and building high pressure that limits marine-layer cooling from Puget Sound. The close split between 70-71°F and 72-73°F outcomes reflects minor model spread on afternoon mixing depth and the precise timing of any residual onshore breeze, both of which can alter the daily maximum by 1–3°F. Ongoing seasonal warming above the 69–74°F June climatology supports the market’s tight clustering around these bins, while lower-probability tails capture tail risks from unexpected cloud build-up or stronger sea breeze. Updated model runs and the 4 p.m. local observation will provide the final resolution data.
