Trader sentiment on Seattle's March 25 high temperature hinges on the National Weather Service's latest forecast pinning a peak near 51°F under partly cloudy skies, with ensemble models like GFS and ECMWF averaging 49-51°F amid cool marine air inflow. The razor-thin gap between 50-51°F (43%) and 48-49°F (38.5%) reflects uncertainty in morning stratus cloud persistence versus afternoon clearing, as low-level onshore flow limits solar heating in the Puget Sound region. Historical March 25 highs average 54°F, but this year's cooler anomaly from lingering Pacific cool pool tilts odds downward, with traders eyeing hourly observations for resolution.
