A little update for today, but time is a little limited.
Northwest: More snow will fall in Oregon today, specifically from Eugene to Portland and moving east. New snowfall totals from this second storm are going to average 3 to 6 inches west of the Cascades with the Eugene area at least seeing a changeover to sleet, freezing and snow tonight but mostly all snow farther north. Three to six inches are also likely through the Columbia Gorge to the Redmond/Bend region. Snow developing tonight continues into part of Saturday in the Tri-Cities area with Pendleton and surrounding areas probably getting 2 to 6 inches. Saturday, Saturday night and Sunday in northwest Oregon temperatures modify enough for mixed precipitation but also light precipitation as all the real storminess stays south. However, roads will continue to be slick and a little ice on top of the snow is not much of an improvement.
California: Not much change in my thinking from yesterday so you can go back to yesterday's posting to see what was said. Here are two interesting graphics though. The first is Total Precipitable Water in the atmosphere across the Pacific and into the West as derived by satellite.
Notice the nose of high TPW (greens) aimed right at northern California. And this is the reason the models all are consistent on bringing this area the heaviest precipitation through Sunday night. Here is what the GFS has for total precipitation from Friday morning to Monday morning.
I will try to do some tweeting over the weekend but I also will be enjoying some down time with the grand kids and wife. After this week, the down time is definitely needed.

A rather extended period of unsettled weather will be occurring over parts of California and the Southwest
The remainder of the week a large building ridge of high pressure takes over
There will be more showers and thunderstorms are likely that can produce very heavy downpours in Arizona.
This rain caused problems with flash flooding producing some damage and there were a few swift water rescues.
Computer models are insistent that a rather strong piece of energy will move through California Tuesday, bringing more widespread rainfall.
