You can blame a ridge of pressure over the Pacific for pushing a layer of cool, cloudy marine air over western Washington, says KPLU weather expert Cliff Mass.
Saturday will be "the best day" of the weekend, as the sun is likely to burn through for at least part of the day.
After that, expect cloudy and occasional showers starting Sunday and through much of next week, with temperatures mainly in the upper 50s to lower 60s.
At least, for vegetable gardeners, the warmer temperatures that we've had over the past month raised soil temperatures, says Mass.
