Official National Weather Service observations at Seattle-Tacoma International Airport (KSEA) confirm the highest temperature on April 21, 2026, reached 58°F at 4:53 PM local time, driving trader consensus to 100% on the 58-59°F outcome as final data solidifies. This aligns closely with pre-event forecast model consensus from the National Weather Service, which projected highs near 59°F amid persistent marine layer clouds and cool onshore flow typical for Pacific Northwest spring conditions, suppressing temperatures below seasonal averages (normal max around 57°F). While data revisions are rare post-validation, a realistic challenge would require an official correction from ASOS instrumentation errors or overlooked peak readings, though hourly timeseries show no such anomalies. Traders await full daily climate summary for closure.
