Recent forecasts from meteorological models, including those aligned with National Weather Service guidance, position Seattle's September 26 high temperature in the low to mid-60s°F, driving the strong market-implied odds for 62-63°F and 64-65°F outcomes. A cooling trend following recent highs near 66°F, combined with increasing cloud cover, northwest winds, and typical late-September marine air influence, supports this range, which aligns closely with climatological averages around 67°F but reflects current atmospheric conditions. Trader consensus reflects these model runs, though inherent forecast uncertainty from evolving pressure patterns could shift final observed highs slightly higher or lower by resolution.
