Forecast models from the National Weather Service and private sources indicate Seattle's overnight low on August 29 will likely settle in the mid-50s, driven by an approaching frontal system that brings increased cloud cover, scattered showers, and reduced radiational cooling under marine-influenced air. This setup aligns with seasonal norms near 56°F while limiting deeper drops, though variations in precipitation timing and wind could push readings toward 54–57°F or briefly lower. Trader consensus splits across these bins amid typical late-summer forecast spread, with lower probabilities for extremes reflecting the low historical likelihood of sub-50°F readings this time of year absent unusual cold advection. Updated model runs overnight will refine the exact minimum ahead of resolution.
