Trader consensus on Polymarket assigns 100% implied probability to Seattle's highest temperature on March 25 reaching 50-51°F, supported by verified observations from the National Weather Service station at Seattle-Tacoma International Airport (Sea-Tac), which recorded a daily high of 51°F amid persistent marine stratus clouds and cool northerly flow. Leading up to the date, NOAA's Global Forecast System (GFS) and European Centre models converged on subdued temperatures below seasonal norms (March average ~54°F), driven by a strong Pacific high-pressure ridge blocking warmer air. No significant deviations occurred, with cloudy skies capping daytime heating. This positioning faces minimal challenge; only an official data correction from NWS—extremely rare post-preliminary reporting—could alter resolution, as final verified records are authoritative.
