National Weather Service forecasts project a high near 69°F at Seattle-Tacoma International Airport (KSEA) today under sunny skies and a strengthening high-pressure ridge over the Pacific Northwest, driving trader consensus to 100% implied probability for 68°F or higher. Morning observations from KSEA show temperatures climbing from mid-50s lows with clear conditions and light northerly winds aiding daytime heating, aligning with short-range model consensus (HRRR, RAP) for peak temperatures in the mid-afternoon. This exceeds the May 11 climatological normal of 66°F amid a recent warm trend following early-month records. Realistic challenges include sudden marine stratus intrusion or unforecasted Puget Sound cooling, though current satellite data indicates low risk; monitor hourly METARs and NWS updates through 4 PM PDT for confirmation.
