Recent National Weather Service forecasts for the Seattle-Tacoma area indicate sunny conditions and highs in the mid-to-upper 80s°F on August 6, positioning the 88–89°F bin as the market leader with 36% implied probability. Model consensus from official sources shows limited cloud cover or marine influence, supporting modest daytime warming consistent with the ongoing warmer-than-average summer pattern across the Pacific Northwest. Key variables include potential patchy smoke reducing insolation and subtle steering patterns that could shift the high by a degree or two, while historical August climatology at Sea-Tac Airport averages near 77°F with rare exceedances above 90°F. Traders appear to weight the latest deterministic runs heavily given the proximity to resolution, with lower-probability tails reflecting uncertainty in boundary-layer mixing and any late forecast adjustments.
