Clouds have been increasing overnight and we're starting out chilly again for your Friday morning. An area of low pressure to our north will provide a quick moving wave of moisture over northern California starting this afternoon and lasting through early Saturday. A Winter Weather Advisory is set to go into effect in Northern Trinity County from 1pm this afternoon through 1am Saturday morning down to 4000', where up to 8 inches of snow will be possible. Northwest Shasta County areas under 2500' will be under a Winter Weather Advisory from 1pm this afternoon through 7am Saturday, and will have the potential for up to around 6 inches of snowfall during that time. The Sierra will be under a Winter Weather Advisory above 6000' from 4pm this afternoon through 10am Saturday and we'll have the potential for up to a foot of snow in that area through early Saturday. Snow levels will be at their lowest at the onset of the shower activity and will gradually rise through early Saturday morning. Sierra locations could see snow down to as low as 3500', but it is not expected to stick there. This winter weather will bring the potential for travel impacts to our region tonight through tomorrow, and a more substantial wet weather event will bring additional impacts late Saturday night through early Monday morning.

Clouds are increasing over northern California this morning, and we'll continue to see mostly cloudy skies through the day. Temperatures are starting out in the 30's to 40's in the valley and foothills, and in the teens to 20's in most mountain areas. Winds are starting out of the north to around 10mph, but will shift to the southeast later today. Showers will become possible as we head into your afternoon, and will become more widespread tonight. The heaviest showers will be in the mountains, with only a trace of rain expected in the valley through early Saturday morning. High temperatures will top out in the mid 50's in the valley today, in the lower 40's to around 50 degrees in the foothills, and in the upper 30's to upper 40's in the mountains this afternoon.

A break in the wet weather is expected after Saturday morning and is expected to persist through late Saturday night. A more substantial wet pattern will develop from Saturday night through early in the day on Monday. This will bring heavier rain and snow to our region, but will also have slightly higher snow levels. Valley areas could see up to an inch of rain through this weekend, while mountain areas have the potential for upwards of 2 inches in some locations from today through early Monday. Temperatures will end up warmer for the overnight hours, and will stay up to around average for this time of year for the afternoons through this weekend.

Dry weather is projected to return to our region on Monday, but that could be short-lived. Models are hinting at another wet system bringing modest showers into your Tuesday into Wednesday forecast of next week. Models are currently split on the potential for more showers next week, but what does look very likely is temperatures staying warmer overnight and cooler for the afternoons. Make sure you've got your jacket and umbrella handy, and don't forget to take it easy on those wet roads over the next few days.

Strong wind continues to blow through the valley this afternoon, and will last through the evening. Thursday will still be a fairly breezy day, but the wind won't be as strong and our temperatures will be warmer. More wind is coming Friday and Saturday.
