Current National Weather Service and model guidance point to a Seattle high temperature near 75–78°F on August 19, driven by persistent onshore flow, a moderating marine layer, and weak ridging aloft that limits daytime heating. Ensemble spreads and local variations in cloud cover or wind direction keep the central outcomes from 72–81°F roughly equiprobable at market-implied odds near 25% each, while historical August climatology (average high ~77°F) and recent warmer-than-normal conditions support the modest tail probabilities above 82°F. Minor forecast revisions from the next model runs or afternoon sea-breeze strengthening could shift resolution among these tightly bunched bins.
