I try to answer comments as I get them but sometimes I miss them or they don't show up for a day or so. There was recent comment about the dry weather and chilling hours. If you are in the valley or low lying areas the dry air will cause colder than normal nights and therefore more chilling hours. Also when you couple dry air and low soil moisture you get colder nights. Normally you get more chilling hours during clear dry weather than cloudy wet weather. Another question was about what maps I use for mid and long range. I look at the models from the U.S. (GFS), Europe, UK, and Canada. I also use my experience (40+years) forecasting in Northern California.

Today will start off mostly sunny but clouds will increase during the afternoon. Temperatures today will be a little cooler than yesterday. This morning's satellite picture (below) shows what looks like an impressive storm approaching the coast. However, this system will be like Sunday nights system and weaken rapidly as it moves inland. Light to moderate rain will occur tonight and early Wednesday along the north coast and over Trinity, and Siskiyou counties. The storm will be dying as it moves east so the rest of the north state will see some clouds but only scattered light showers. Snow levels will be around 5000 feet. The storm will be east of our area by Wednesday afternoon and skies will be clearing. Thursday high pressure begins to build over the western U.S. and by the weekend is a fairly large system that covers the western U.S. (see map below) This will bring mostly sunny skies to our area with daytime temperatures 7 to 11 degrees above normal.
This high pressure area is over the western U.S. and to our east, while the previous one was along or off the coast to our west. This means storms will dissipate as they reach the coast and hit the high. So we will see some clouds at times during the next week to 10 days but other than maybe some sprinkles on the coast we will be dry and mild.
The longer range models show the high pressure area continuing to build northward during the first half of February. This means what will probably happen is the jetstream will eventually break underneath it and move into Northern California. If this happens it looks like it will be after the 10th of the month.
