Recent National Weather Service and model guidance indicate a high of 65–68°F for Seattle on September 14, driven by lingering marine influence and light southerly flow following overnight rain on the 13th. Overcast to partly sunny skies with minimal daytime heating and dew points in the mid-50s limit afternoon warming, keeping readings near or slightly below the seasonal average of 71°F. Ensemble forecasts show tight clustering around this range, with only modest potential for brief clearing to push toward 68–69°F. Trader consensus reflected in the 49.5% and 36.5% probabilities on the 66–67°F and 68–69°F bins aligns closely with these official projections, while lower-probability outcomes account for typical forecast uncertainty in coastal temperature verification.
