Recent forecasts from NOAA-aligned sources and meteorological models indicate mostly clear skies and northerly flow under high pressure for Seattle on September 8, supporting daytime highs near the long-term average of 72.4°F at Sea-Tac. Subtle differences in boundary-layer mixing, dew-point suppression, and afternoon solar heating rates explain the tight spread between 72–73°F and 74–75°F bins, with traders assigning roughly equal weight to each. Light northerly winds around 5–9 mph and minimal cloud cover favor modest warming above climatology, though any increase in marine influence or earlier marine layer return could cap readings at the lower end. Updated model runs and local observations through September 7 will refine the exact maximum before resolution.
