Trader consensus on Polymarket favors a Seattle high temperature of 56-57°F at 41% implied probability, driven by the latest National Weather Service forecasts and ensemble model runs projecting mid-50s peaks on April 7 amid a cool upper-level trough over the Pacific Northwest. Persistent marine stratus clouds and light onshore flow are capping daytime heating, consistent with early April climatology where Seattle's average high hovers around 57°F and historical analogs from recent rainy, chilly periods (per Old Farmer's Almanac outlook for April 1-7). Lower odds for warmer outcomes reflect limited ridging potential, while cooler bins account for possible increased cloudiness; watch NWS Seattle's daily updates and ECMWF/GFS model refreshes for shifts ahead of resolution based on official Sea-Tac Airport observations.
