Sierra picked up another 7 inches yesterday as the storm rotated across the Tahoe basin. That brough the storm total to 8 inches. The March total is already up to 2 feet with more snow in the forecast this weekend and maybe a lot more snow next week.
Low pressure is going to setup in the Northeast Pacific by Saturday and will send the jestream underneath into the Pacific NW this weekend. Several waves will come onshore starting Saturday. The first one will stay to our North but the second for Sunday is trending further South and could bring several inches Sunday into Monday.
Then as another low sets up in the Northeast Pacific a strong jetstream aims a hose of moisture at Northern CA. Some of the forecast models show a SW to NE oriented jet sitting over Northern CA which could dump tons of rain on Northern CA to our Northwest. Other models have a more W to E oriented jet pointed right at Tahoe with continues waves of moisture through the week.
The first solution would bring the chance for several inches or more the end of next week after the storm on Sunday/Monday. The second would bring several feet through the week. Tomorrow is 5 days out where the forecast models usually start to come into better agreement on a solution. The potential is there for the biggest snow week of the season, but we need a lot more of the forecast models to agree first.
Either way I'm pretty confident we will see a couple snow events next week even if they are small/moderate sized. BA
