National Weather Service forecasts for Seattle on May 15 project a high temperature near 52-55°F under mostly cloudy skies with a chance of showers, driving the 97% market-implied probability for 57°F or below as traders price in strong model consensus from GFS and ECMWF ensembles. This positioning stems from a recent cool-down after early May's record heat, with persistent marine stratus, cool air advection from the Pacific, and a weak upper-level trough suppressing warming—conditions well below the historical May 15 average high of around 65°F. Ensemble spreads show limited upside risk, though unexpected clearing of low clouds or a model forecast bust could challenge this, with the next NWS update expected Thursday evening providing further clarity on boundary layer stability.
