Recent National Weather Service forecasts indicate mostly cloudy skies and a daytime high near 64°F for Seattle on October 1, aligning closely with climatological norms for early October. Trader consensus, however, assigns the highest implied probability to 66-67°F, reflecting model variability in short-range guidance and potential for modest warming under variable wind patterns or reduced cloud cover. Lower bins around 62-63°F and below capture downside risks from persistent marine influence or stronger onshore flow, while warmer outcomes above 68°F remain possible if ridge amplification occurs. Key variables include steering winds, diurnal heating under partial clearing, and updates from the next model runs ahead of resolution.
