Recent National Weather Service forecasts and supporting model guidance indicate minimum temperatures for Seattle on October 16 will likely fall in the low to mid-50s Fahrenheit, driven by building high pressure, light winds, and clear to partly cloudy skies that permit moderate radiational cooling overnight amid mild Pacific air. This setup contrasts with historical October averages near 46°F and supports the market's emphasis on sub-50°F bins, though spread across multiple outcomes reflects model uncertainty in exact overnight lows and potential for slight forecast revisions. Key upcoming updates from NWS and NOAA will refine these projections ahead of resolution.
