Official observations from the Seattle-Tacoma International Airport (KSEA) Automated Surface Observing System confirm the highest temperature on April 14 reached 46-47°F amid overcast skies, light rain, and a persistent marine layer that suppressed daytime heating under Pacific Northwest spring patterns. National Weather Service forecasts had anticipated a high near 50°F with precipitation, but actual soundings showed cooler air masses and cloud-induced adiabatic cooling aligning with model consensus from GFS and ECMWF ensembles. This data, reported via Weather Underground and NWS daily climate summaries, drives the 100% trader consensus, reflecting verified measurements with minimal uncertainty. Revisions could arise only from rare quality-control adjustments to preliminary ASOS readings, though historical precedent indicates near-zero likelihood post-24-hour validation.
