An upper level trough digs out into the West with several areas of low pressure pushing over northern California between now and Wednesday.
The first is already here and rain will continue into the early overnight, locally heavy at times with the .50-1” potential (some locations could see as much as two inches).
SE winds will be locally gust with the system. Another low tracks into the area right on the heels of the first with more rain and about the same potential, another .50-1” of rain with locally higher amounts (graphics with potential are posted on KSBY and Dave Hovde’s social media @TVDave).
More SE winds prior to the next system also allow a connection to deep moisture, which helps explain the higher potential rain accumulations with the two systems.
After the second system pulls out Wednesday some high pressure builds in, this will help clear out the skies near the coast but some areas of dense valley fog may also result from trapped low-level moisture.
There is a third cold front, which looks to push into the area either late Friday or early Saturday for more showery rain.
I know the big question after that is the Christmas forecast and right now it looks pleasant as high pressure builds into the region.
