Latest National Weather Service guidance and ensemble model consensus from GFS and ECMWF project Seattle's highest temperature on April 1 clustering around 48-51°F, driving the tight race among top market outcomes as traders weigh marine layer persistence versus potential clearing. Following atmospheric rivers that soaked the Pacific Northwest through mid-March, a lingering cool, moist air mass under weak high pressure has capped daytime heating, with low stratus clouds limiting insolation—favoring 46-49°F if overcast dominates, but 50-53°F possible with afternoon breaks. NOAA's spring 2026 outlook signals 40-50% odds of above-normal temperatures amid La Niña-to-neutral ENSO transition, yet short-term uncertainty persists in cloud evolution and offshore winds. New model runs and NWS updates expected within 24 hours could shift probabilities further.
