Current National Weather Service and ensemble model consensus forecasts position the overnight low for Seattle on August 27 near 58°F, aligning with the market's leading 58-59°F bin at 45.5% implied probability. Radiative cooling under partly cloudy skies, combined with light southwesterly flow and moderating marine influence from the Puget Sound, supports mid-to-upper 50s readings slightly above the 1991–2020 climatological average low of 55.9°F. Recent model runs show minimal spread and no significant revisions from prior guidance, reinforcing trader focus on the 56–59°F range amid stable late-summer conditions.
