Current National Weather Service and ensemble forecasts project Seattle's October 6 overnight low near 50–52 °F under building high pressure and light northerly flow, placing the daily minimum in the middle bins. Clear to partly cloudy skies overnight support moderate radiational cooling, while any increase in onshore marine influence or low-level cloud cover could limit temperature drops and keep readings above 52 °F. Conversely, drier air and calm winds would enhance surface heat loss, raising the chance of readings at or below 45 °F. Model runs remain sensitive to small changes in 850 hPa temperatures and boundary-layer moisture, with the next 48-hour updates from NOAA likely to sharpen resolution of these variables before market close. Historical October minima average near 49 °F, underscoring how modest deviations from the current ridge pattern could shift outcomes across the tightly priced extremes.
