Trader sentiment for Seattle’s August 14 high centers on National Weather Service guidance projecting an 80–82°F peak, driven by moderate zonal flow aloft and persistent onshore marine air that limits daytime heating despite the broader warmer-than-average Pacific Northwest summer. Recent model runs show limited spread, with sea-surface temperatures near normal and no strong offshore flow or subsidence to push readings into the mid-80s. Historical climatology places mid-August averages near 77°F, so current conditions represent a modest positive anomaly. Key resolution factors include the exact maximum recorded at official stations before any marine push strengthens overnight. Updated NWS and NOAA short-range guidance expected within the next 12–24 hours will provide the final inputs for market adjustment.
