Showers are returning to the Northern California this afternoon and will continue through early Friday. This wet system is not expected to pack much of a punch, but almost everyone will see at least a little shower activity before it tapers off early to mid day tomorrow. Up to around a quarter of an inch of rain can be expected in the valley, but most areas will see closer to a tenth of an inch. Mountain areas are projected to get up to around 2/3rds of an inch of rain through early to mid day tomorrow. Snow levels are expected to stay well above 7000', so this will almost exclusively be a rain shower event. The potential for some light and scattered showers will linger into early Friday, but it does look like we'll get a break from the wet weather on Friday afternoon. Patchy fog will also be possible for the start of your Friday, so you may want to give yourself a little extra time to get to where you're going in the morning. Low temperatures will dip into the mid 40's in the valley overnight, and mountain areas can expected to start out in the mid 30's on Friday morning. High temperatures are projected to end up in the mid to high 50's in the valley, and in the mid 40's in the mountains on Friday afternoon.
The next wet system will arrive along the coast between late Friday night and early Saturday morning. This system will be another warm one with high snow levels, but is expected to bring a lot more moisture to our region. The current outlook puts showers along the Northwest portion of Northern California early on Saturday and then has them slowly tracking Southeast across our entire region for the remainder of the day. The heaviest rain and snow can be expected at night on Saturday. Snow levels will be very high on Saturday, with most projections putting them between 7000' to 8000', but they will dip down to around 6500' overnight into Sunday. Snow levels will then dip down to around 5000' through the day on Sunday. The heaviest rain and snow on Sunday is expected during the morning hours, with ligher amounts through the afternoon. Valley areas could see up to around an inch and a half of rain through this weekend, and mountain areas will see up to around 2 inches of rain. Snow totals are expected to be very modest since snow levels will be high for most of the weekend, but we could end up with 4 or more inches of snowfall above 7000'. Temperatures are not expected to change much through your weekend in the valley, but mountain areas will have slightly cooler overnight low temperatures.
Scattered mountain showers will be likely as we head into your Monday, but valley areas are expected to be mostly dry. Skies will be cloudy and temperatures will be slightly cooler than what we had over the weekend. The current longer range outlook keeps the north state cloudy, but mostly dry from Tuesday through the middle of next week.
