What's Ahead:
Another chilly night with temperatures in the upper 20s and low 30s! Clear skies for much of the night will lead to patchy fog in the morning which will clear to mostly sunny skies. Throughout the day Friday, clouds will increase as our big ridge of high pressure weakens. High temperatures will be in the 40s.
A weather system approaching from the northwest will bring rain Saturday first to the Canadian border and north coast. The rain will develop for all of western Washington Saturday night and showers will continue Sunday.
