FORECAST DISCUSSION:

Another storm system is drenching California. Some of the moisture from this system is rotating northward into Washington. As the system moves off to the east the showers will diminish. We should be between weather systems on Tuesday for a mainly dry day. However, there might be a couple of showers to deal with.
 
Another system will pass to the south on Wednesday. That system will pull in some cooler air that will lower the snow level to 500 to 1,000 feet. later in the day. A few wet snowflakes may mix in with the rain. That will continue on Thursday as well. At this point, no accumulation is expected. 
 
The rain and snow showers will end early Friday. We should see a dry start to the weekend. Then, high pressure will build in. After some morning fog, we'll see the sun return. It will still be cool with highs in the mid 40's.
