Latest National Weather Service forecasts and ensemble model guidance for Seattle on August 14 point to a high near 80°F under mostly sunny skies, with minor variations in predicted peak values across runs driving the tight clustering of market-implied odds around 78–83°F. Subtle differences in the strength of onshore marine flow, timing of daytime heating, and any residual effects from the strong Pacific high-pressure ridge sustaining Seattle’s warmer-than-average summer explain the spread between the leading bins. Historical August climatology shows typical highs near 77°F, but current conditions favor a modest exceedance. Updated model cycles and the next NWS forecast discussion represent the next likely catalysts for shifts in trader positioning.
