Tuesday was another mostly sunny and mild day around the North State. We won't see much change tomorrow, but rain will return by the end of the week.
High pressure remains in place over California, keeping our skies mostly clear and our temperatures mild. Not much change tomorrow, but clouds will thicken Thursday ahead of our next storm coming our way.
Friday should be a rainy day, as an Atmospheric River (another name for a Pineapple Express) targets northern California. This will be a long band of subtropical moisture originating from near Hawaii that soaks us. The Sacramento Valley could get rain shadowed a little, but I still expect 1/2" to 1" of rain for us. The mountains should really get soaked, and look for a lot of rain on the Ridge. Since this moisture is from near Hawaii, it'll be warm... so snow levels will be high, starting around 6000'.
This plume will work southward by Saturday, leaving us with scattered showers. Cold air should work in by then, so snow levels will fall to near 3500'... but it'll just be a few snow showers in the mountains by then, not too much anymore.
Sunday is still undecided. One model wants to leave us completely dry, while another good one is soaking us with a potent storm! The actual solution probably lies somewhere in the middle, but we'll have to wait another day or two for consensus between the Euro and GFS models for a good handle on what will happen.
Another storm could target us next Tuesday. Overall, the extended forecast continues to look wet!
