Persistent high pressure over the Pacific Northwest is sustaining mild early-October conditions in Seattle, with official forecasts from NOAA and European models projecting an overnight low near 52–55°F on October 3 under partly cloudy skies and light northerly flow. This setup limits strong radiative cooling while preventing cooler marine air intrusion, keeping temperatures well above the historical average low of 49.4°F yet far from extreme warmth. The near-even market split between a 45°F-or-below outcome and 64°F-or-higher reflects genuine short-term uncertainty in cloud cover and boundary-layer mixing, which can shift minimum readings by several degrees. Updated NWS model runs and surface observations over the next 48 hours will clarify whether clearer skies allow deeper nocturnal cooling or if residual moisture maintains milder readings.
