There is a storm currently moving onshore pushing towards Tahoe. As it interacts with the ridge of high pressure currently in place it will split with the heaviest precip heading South down the CA coast. It looks like enough moisture will make it into the Tahoe Basin to bring 1-3 inches to the mountain during the day on Tuesday.
The ridge builds back in the second half of the week. Then over the weekend the ridge begins to shift West off the coast. That will open the door for some colder air to come down from the North and storms to come into the Pacific NW.
Depending on how far West the ridge shifts away determines how far South the storms could dive down the coast. Several models show a cold snow showery pattern setting up Sunday and into next week. The trend is in this direction so hopefully it continues and we will see more snow next week.
Looking long-range there is suggestion that the ridge continues to retrograde NW in the Pacific opening the storm door a little more. We will keep an eye on that and hope for good snowy second half to February. BA
