Official observations from the National Weather Service's automated surface observing system (ASOS) at Seattle-Tacoma International Airport (KSEA)—the market's authoritative data source—confirm a high temperature exceeding 62°F on April 20, 2026, solidifying 100% trader consensus on that outcome amid negligible 0.1% odds for 60-61°F. This reflects the persistence of a strong upper-level ridge over the Pacific Northwest, delivering clear skies, light winds, and well above-normal warmth following 74°F on April 19, far surpassing the late-April climatological average of around 60°F. Model consensus from NOAA's Global Forecast System (GFS) and High-Resolution Rapid Refresh (HRRR) had anticipated this mild pattern with highs in the 70s. Post-event, only an unprecedented data revision from preliminary METAR reports to the final climatological summary could challenge resolution, a scenario deemed implausible given consistent hourly readings.
