Recent forecast guidance from the National Weather Service and local models points to an overnight low near 58°F in Seattle on August 26 under partly cloudy skies with light southerly flow, consistent with typical late-summer marine influences that moderate radiative cooling. Trader sentiment remains closely divided because ensemble spreads show potential for 3–5°F deviations depending on exact cloud timing and urban heat island effects, keeping probabilities balanced between sub-50°F outliers and warmer scenarios above 65°F. Historical August lows average 56°F with low variability absent strong frontal passages, and the absence of significant model updates in the past 24 hours sustains the equilibrium across resolution bands.
