National Weather Service forecast models project a high near 69°F at Seattle-Tacoma International Airport (KSEA)—the market's official observing station—on May 1, driving the 99.1% trader consensus for 64°F or higher amid a dominant upper-level high-pressure ridge over the Pacific Northwest. This setup delivers mostly sunny skies, light northerly winds around 5-10 mph, and efficient solar heating, elevating temperatures 6°F above the May 1 climatological average of 63°F based on 30-year NOAA normals. Model ensembles from the past 24 hours show tight agreement with minimal spread. Realistic challenges include an unexpected marine stratus surge or abrupt onshore flow shift introducing clouds and cooling, though current guidance indicates low likelihood; watch hourly NOAA updates through evening for refinements.
