Recent National Weather Service forecasts for Seattle on August 24 project a sunny high near 77°F under northerly flow at 10-15 mph, supporting the market's tight clustering around 76-79°F outcomes. Persistent high pressure and minimal marine layer influence favor clear conditions that allow efficient daytime heating, though subtle differences in wind timing or boundary-layer mixing could shift the peak by 1-2°F. Model consensus remains stable with low precipitation odds, yet the modest edge for 78-79°F reflects trader adjustments for potential slight under-forecasting in similar setups. New NWS updates and morning soundings will provide the final resolution inputs before trading closes.
