Scattered showers persisted across northern California through early this morning, and fog was an issue in some northern areas early on today. Dry weather and clearing skies then returned for your afternoonand temperatures warmed up to several degrees above average. Valley areas topped out in the mid 50's to low 60's this afternoon and mountain areas mostly ended up in the low to mid 40's. Winds have been moslty light and out of the South this afternoon. Fog is expected to develop overnight tonight and could be dense in some areas on Thursday morning. The break from the rain will continue through around mid day on Thursday and then the next wet system will move into northern California between the afternoon and evening. There are models hinting at showers returning to the mid valley before noon, but those seem to be the outliers. Snow levels will be high and moisture amounts will be limited with this wet system. Snow levels will be above 7000'. The current outlook brings around a tenth of an inch of rain to the valley and up to around a third of an inch of rain to the mountains through early Friday afternoon. Temperatures will stay warm and will be similar to what we had outside today through Friday.
Another warm system is expected to arrive in our region late Friday night into early Saturday. Showers will mostly impact areas closer to the coast on Saturday morning and will then spread through the remainder of northern California through Saturday afternoon. This system will be much wetter than the Thursday into Friday system, and is expected to persist through Sunday. Most of the showers are expected to be in the form of rain as snow levels will be above 6000' on Saturday. On Sunday snow levels are projected to drop to around 4500', so snow is in the forecast for the latter part of your weekend. Up to around an inch of rain can be expected in the valley this weekend and mountain areas can expect up to around 2 inches of rain. Between 4 to 8 inches of snow will be possible down to around 7000', with more limited amounts below that. High temperatures are not expected to change much if at all through your weekend, but overnight low temperatures will be warmer. Valley areas may even stay in the low 50's on Sunday morning.
We're expecting to dry out in the valley early next week, but some mountain showers could very well linger into your Monday forecast. High pressure will build back into the West Coast Monday into Tuesday and that should bring the return of dry weather to most areas early to mid week. Temperatures are projected to stay above average through your extened forecast, but may end up slighty cooler than your weekend early next week.
