Trader consensus on Polymarket tilts toward a Seattle high temperature of 60-61°F (39.5% implied probability), closely trailed by 58-59°F (31%), reflecting National Weather Service forecasts showing partly cloudy skies with highs near 59-60°F at Seattle-Tacoma International Airport after a recent cool-down from 70°F readings earlier this week. This positioning stems from a marine layer influx moderating temperatures via persistent stratocumulus clouds over Puget Sound, capping diurnal heating, while partial afternoon clearing in model ensembles (GFS, ECMWF) could push peaks into the low 60s. Historical April 12 highs average around 59°F amid spring variability; low precipitation odds (20-50%) and light onshore winds differentiate outcomes, with final NWS updates expected today clarifying burn-off timing before observations begin.
