Latest National Weather Service and ensemble forecast models, including GFS and ECMWF, project Seattle's high temperature on April 5 around 62°F, aligning trader sentiment with the 62-63°F outcome at 35.5% implied probability, followed closely by 60-61°F at 23.5%. This positioning reflects NOAA Climate Prediction Center's spring outlook favoring above-normal temperatures across western Washington—40-50% chance for April—with a developing high-pressure ridge suppressing marine layer clouds and enabling daytime heating beyond early April climatological normals of 57-58°F. Recent model runs over the past 48 hours show consistent mild conditions post-wet March, though uncertainty persists from potential jet stream shifts or lingering stratus; watch NWS updates Friday for refined guidance ahead of resolution.
