National Weather Service forecasts for Seattle on October 2 project a high near 70°F under partly sunny skies after morning clouds, driven by a stable high-pressure ridge over the Pacific Northwest that limits marine air intrusion and supports light southerly flow for afternoon warming. This aligns with trader consensus, where the 70-71°F bin holds the strongest market-implied odds at 48%, followed by 68-69°F at 33%. Model agreement across recent runs shows minimal deviation, with temperatures tracking slightly above early-October climatological averages. Key resolution thresholds center on official observations from Sea-Tac or downtown stations, and any late-day clearing or wind shifts could nudge the peak within the leading ranges.
