Current short-term forecasts from the National Weather Service and ensemble models project overnight lows in Seattle on September 7 near the long-term average of 54.5°F, with most guidance clustering between 52–57°F depending on cloud cover, wind patterns, and marine influence from Puget Sound. This keeps the implied probabilities tightly bunched across the 50–57°F bins while assigning the highest weight (29%) to 66°F or higher, reflecting the limited but real chance of a warmer night under clearer skies or stronger southerly flow. Historical data show daily minima on this date rarely drop below 48°F or exceed 60°F in early September, so the market distribution largely tracks normal seasonal variability rather than any anomalous atmospheric setup. Updated model runs and local observations over the next 48 hours will narrow the range as the exact timing of any marine layer or wind shift becomes clearer.
