Trader consensus on Polymarket assigns 100% implied probability to a highest temperature of 54-55°F in Seattle on April 16, backed by official National Weather Service observations from the Automated Surface Observing System at Seattle-Tacoma International Airport (KSEA), which recorded a peak of 55°F around late afternoon under partly cloudy skies. This positioning stems from forecast model consensus from NOAA and NWS predicting a modest daytime high near 55°F amid a cool Pacific marine air mass, morning lows of 36-37°F under frost advisories, and light southerly winds capping warming below April climatological norms of about 58°F. While final quality-controlled data from the National Centers for Environmental Information could prompt minor revisions, such changes are exceedingly rare for routine observations, solidifying the outcome.
