National Weather Service forecasts for Seattle-Tacoma International Airport indicate a high near 49°F on April 15, 2026, amid steady rain and gusty south winds up to 34 mph, driving trader consensus to cluster tightly around 46-51°F outcomes. Persistent low-level clouds and marine air from Puget Sound suppress daytime heating, while a trailing cold front from recent mountain winter storm warnings maintains cool mid-40s baseline temperatures observed this morning. Model ensembles like GFS and ECMWF show minor divergence—some runs cap peaks at 47°F under heavier precipitation, others allow brief clearing for 49°F—fueling the near-even split between 46-47°F (39.5% implied probability) and 48-49°F (41.0%). Hourly observations and afternoon forecast updates will clarify the peak before evening resolution.
