Here's the Area Forecast Discussion from the Meteorologists at the National Weather Service office in Sacramento. They forecast for most of the North State.
This is where you can dive deeper into the WHY of what the weather is doing. They'll explain the meteorology of our current weather pattern, and what will cause it to change. If you want to learn a lot more about our weather I highly recommend reading these over the course of a week (or longer!) to get a true understanding of what our weather is doing.
Click here for a variety of graphical forecasts from the National Weather Service: High & Low Temperatures, Wind (direction, speed, and gusts), Rain (percentage chance & total amounts), Snow (percentage chance & total amounts), Dry or Severe Thunderstorm chances, and other products. Click on the location you want the forecast for. Change the forecast with the dropdown that says Maximum Temperature in the upper left. The slider to the right of that will change your time... it runs in 6 hour segments, so you may have to do a few to get a storm total.
