Dense fog in the morning, and showers returning this evening. Fog is by far the biggest issue early on today, and will be in issue for commuters in the valley this morning. The majority of the valley has had visibility dip to around a quarter mile early on today. Drivers are advised to give themselves extra time to get to where they're going, extra space between vehicles, make sure your lights are on, but not to use your brights in the fog. Temperatures are stating out in the low to mid 40's in the valley this morning, and I the high 20's to low 40's in the mountains. Fog should mostly clear out by noon, and light showers will return for your afternoon. High temperatures are projected to end up in the high 50's to low 60's in the valley, and mountain areas will end up in the low to mid 50's this afternoon. Winds are expected to stay light.
The heaviest precipitation will be in store for later tonight through early Tuesday morning. around a half an inch to 6 tenths of an inch of precipitation is expected from this system. Snow levels will stay high, and are only projected to fall to around 7000'. Mostly dry weather will be in store for Tuesday afternoon through Wednesday. A cooling trend is on the way in your extended forecast. Valley areas will stay in the high 50's to low 60's through Wednesday, but will become much cooler later this week. Showers will return to the region on Thursday, and will last into Friday. That system will bring much lower snow levels, and more substantial precipitation to the region. Snow levels are projected to dip to as low as 2500' later this week, which means we could get some snow down into the foothills from Thursday through early Saturday.
Some drying is expected for Saturday afternoon, but another wet system will take aim at Northern California on Sunday. Valley areas will be down in the high 40's to low 50's by this weekend.
