Official National Weather Service forecasts project a high near 67°F for Seattle on October 6 under partly sunny skies after morning stratus and patchy fog clear, supported by northerly flow and high pressure over the region. This aligns with the market's strong preference for the 66-67°F bin at 57.5% implied probability. Model consensus and climatological norms for early October place typical highs in the low-to-mid 60s, but today's setup favors modest warming into the upper 60s without significant marine influence or cloud cover. Lower-probability outcomes above 68°F would require stronger offshore flow or clearer conditions than currently indicated, while cooler bins reflect risks of persistent low clouds. Updated NWS guidance and hourly observations through afternoon will refine these probabilities ahead of market resolution.
