Current National Weather Service and ensemble model guidance points to a mild overnight low near 52–53°F for Seattle on October 5, supported by persistent high pressure, offshore flow, and clear to partly cloudy skies that limit radiational cooling. This setup follows a sunny, above-average weekend with daytime highs in the upper 60s to low 70s, keeping the marine layer suppressed. The implied probability favoring 64°F or higher reflects trader assessment of limited cooling potential, while bins clustered in the low-to-mid 50s align with climatological norms (historical Oct 5 average low of 49°F) and the absence of incoming troughs or stronger northerly winds that could drop readings further. No significant model shifts have occurred in the past 48 hours, and the next NWS update or 00Z/12Z runs will provide the final resolution data.
