Latest National Weather Service guidance projects a high near 60°F in Seattle on April 5 under mostly sunny skies with light north winds, following the second-wettest April 1 on record that brought cooler, rainy conditions through April 2. Trader consensus on Polymarket, however, implies 64-65°F as the leading outcome at 36.5% probability, reflecting ensemble forecasts from GFS and ECMWF models showing a building high-pressure ridge over the Pacific Northwest that favors above-normal spring temperatures per NOAA's 40-50% outlook for warmer-than-average April conditions. Seattle's climatological April 5 high averages around 58°F, but clear skies could boost peaks absent persistent marine stratus; new model runs and NWS updates expected today may shift odds as resolution approaches in 48 hours.
