Dense fog has developed in many areas overnight and a Dense Fog Advisory is in effect for portions of the valley from Butte and Glenn Counties to the south through 11am. Visibility down to a quarter mile of less is possible early today. Temperatures are mostly starting out in the 30's in the valley, in the 30's to 40's in the foothills, and in the teens to lower 30's in the mountains for the start of your Thursday. Clouds will be increasing throughout the day, but we are expecting to stay dry until tonight. Winds will be out of the northwest to 10mph in the valley, with gusts up to 20mph possible this afternoon. The Sierra and foothills will mostly have winds out of the east to 10mph. High temperatures are projected to top out in the mid 50's to lower 60's in the valley, in the upper 40's to mid 50's in the foothills, and in the lower 40's to lower 50's in the mountains this afternoon.

A wet system moving into the Pacific Northwest will bring another round of rain and snow showers to our region tonight through mid to late in the afternoon on Friday. A Winter Weather Advisory will be in effect in portions of Trinity County from 7pm tonight through 10am Friday, and for Siskiyou County areas down to 4000' from 10pm tonight through 10am Friday. 4 to 8 inches of snowfall will be possible from this system in those areas. We'll also have 3 to 6 inches of snowfall possible in the Sierra and Southern Cascades from late tonight through Friday evening. Snow levels will be down to around 4000' in the Northern Mountains, and down to around 4500' in the Sierra for most of this time frame. Mountain travel impacts are likely early Friday, and Friday evening. Temperatures will be slightly warmer for the start of your Friday, and a little cooler in most areas on Friday afternoon. We'll also have a Wind Advisory in effect in Modoc County from 4am through 4pm Friday, with the potential for gusts up to 45mph out of the southwest during that time.

High pressure is projected to build back into our region this weekend, and that will result in dry and warmer weather on the way. Valley areas will mostly dip into the mid to high 30's overnight, and then top out in the upper 50's to lower 60's through this weekend. Foothill areas will dip into hte 30's to 40's in the mornings and end up in the upper 40's to mid 50's, and mountain areas will dip into the teens to 20's and top out in the 40's to low 50's on Saturday and Sunday.
