Trader consensus on Polymarket prices a 40% implied probability for Seattle's highest temperature on May 14 at 58-59°F, slightly ahead of 60-61°F at 22%, driven by persistent onshore flow ushering cool marine air and morning rain that suppresses daytime heating via low stratus clouds. National Weather Service forecasts indicate a high near 61-62°F if clouds burn off by midday, but recent GFS and ECMWF model runs cluster outcomes in the 58-62°F range, with ensembles favoring slower clearance amid the marine layer—echoing yesterday's cooler-than-average highs. This pattern shifted from early May warmth due to high pressure retrogression, keeping conditions below the 65°F climatological norm; real-time Seattle-Tacoma Airport (KSEA) observations this afternoon will clarify the peak amid inherent forecast uncertainty.
