Trader consensus on Polymarket prices a 57% implied probability for a 52-53°F high at Seattle-Tacoma International Airport (KSEA) today, closely tracking the latest National Weather Service guidance and converging GFS/ECMWF ensemble forecasts projecting peaks in the low-to-mid 50s amid persistent marine stratus and overcast skies. Yesterday's heavy rainfall—the second-wettest April 1 on record—entrenched cool, moist Pacific air masses, suppressing diurnal heating despite seasonal norms near 58°F. Morning METAR observations report temperatures around 45°F with light rain and onshore flow, limiting afternoon warming potential; clouds from an upper-level low over the offshore waters further cap maxima. Hourly observations through late afternoon will sharpen resolution as the market nears close.
