An upper level low (Shaded “U” shape with blue arrows) returned and pushed a frontal system through the Pacific Northwest, thus returning our rain chances. Over the weekend another weak frontal system should move in. It looks like there will be a dry spell for a while next week until a frontal system shows up next Friday.
