Recent National Weather Service and commercial forecasts, including Weather.com's 10-day outlook, project Seattle's April 4 high temperature near 60°F under partly cloudy skies with light west winds and low precipitation risk, aligning with closely matched trader consensus on 58-61°F outcomes. This positioning stems from NOAA's spring outlook favoring above-normal temperatures for western Washington amid a developing upper-level ridge over the Pacific Northwest, tempered by persistent Puget Sound marine stratus that often caps spring highs in the late 50s. Ensemble spreads in GFS and ECMWF models—driven by variability in cloud cover, onshore flow strength, and ridge amplitude—create uncertainty differentiating the top bins, with daily updates through April 3 expected to sharpen guidance ahead of resolution based on official Seattle-Tacoma Airport observations.
