Trader consensus heavily favors a high temperature of 52-53°F in Seattle on March 26 (44% implied probability), propelled by the National Weather Service's latest forecast predicting a daytime peak near 52°F amid partly cloudy skies, light onshore winds, and a persistent cool upper-air trough over the Pacific Northwest. Ensemble models from GFS and ECMWF reinforce this, converging on low-to-mid 50s with minimal spread, consistent with Seattle's March climatology—average highs around 54°F but skewed cooler this season by lingering La Niña influences and recent observations showing highs in the upper 40s. Nearby 50-51°F and 54-55°F bins capture adjacent model runs, while extremes fade due to stable marine layer moderation.
