Recent National Weather Service forecasts indicate a cooler post-frontal air mass arriving after Friday’s trough, driving trader consensus toward 58-59°F as the leading outcome for Seattle’s October 10 daily maximum. This aligns with model consensus showing highs near 59°F under partly cloudy skies following light morning showers and a shift to northerly flow. Seattle’s Pacific marine influence and the seasonal retreat of the North Pacific High typically moderate temperatures this time of year, with historical October 10 averages around 62°F but current guidance reflecting a stronger-than-normal jet stream dip. Upcoming NWS updates and any model shifts on steering patterns or cloud cover could refine probabilities before resolution.
