Official National Weather Service observations at Seattle-Tacoma International Airport (KSEA) recorded a high temperature of 81°F on May 4, 2026—well above the 74°F threshold—driving the 100% market-implied probability for "74°F or higher," with traders pricing out the 72-73°F outcome amid confirmed data. This marked a record-breaker, surpassing the prior May 4 mark of 77°F from 1992, fueled by a persistent high-pressure ridge promoting subsidence warming, clear skies, and warm air advection atypical for early May's climatological average near 63°F. Preliminary hourly data supports sustained peaks in the upper 70s to low 80s°F; final CLI report quality control could theoretically revise downward if anomalies detected, though such changes rarely alter highs by more than 1-2°F absent equipment failure. Traders await NWS certification for resolution.
