Trader consensus on Polymarket reflects near-even implied probabilities for Seattle-Tacoma International Airport highs of 52-53°F or 54-55°F on April 2, driven by the latest GFS and ECMWF ensemble forecasts converging around 53°F amid climatological normals of 54°F. A recent cold snap with near-freezing morning lows and persistent marine stratus from Puget Sound has capped daytime heating, but an approaching upper-level ridge signals potential partial clearing during peak afternoon hours, differentiating the outcomes. Key uncertainties include boundary layer mixing and rain timing, with NWS guidance showing rain chances near 80% but highs near 50°F conservatively estimated; updated model runs and hourly forecasts today could refine this before resolution.
