A ridge of high pressure delivered beautiful weather to northern California on Friday. The weekend will also begin in a quiet and mild way, but changes including rain, snow and wind are coming over the next week. Friday night and early Saturday morning will be clear and seasonably cool with areas of valley fog possible. Overnight lows will range from the 20s and 30s in the mountains to the 40s and 50s in the valley and foothills. Saturday will be mostly sunny and mild... only slightly cooler than Friday... with highs from the 50s in the mountains to the upper 60s in the valley.
A Pacific storm will begin approaching the West Coast on Sunday, and we can expect increasing clouds. There will be a slight chance of showers Monday along with breezes and a cooldown. Tuesday and Wednesday will be dry but still breezy at times. A larger storm will arrive next Thursday and Friday, with valley rain and mountain snow arriving Thursday, followed by stronger wind Friday. We'll also have a noticeable cooling of our days. Valley lows will range from the upper 30s to the mid 40s, while valley highs will fall from the upper 60s to the lower and mid 50s by late next week.
