Moisture is moving into the Sierra Saturday morning along with warmer air and gusty winds. We are seeing some light snow up top and some drizzle at the base. Ridgetop winds are gusting up to 60+ mph at times which is causing some wind holds.
Heavier precipitation will arrive Saturday afternoon into Saturday night. Ridgetop winds will continue to gust up to 60+ mph at times from the southwest. Highs in the 30s. Snow levels will fluctuate between 7000-8000 ft. through Saturday evening with rain at the base. A few inches of wet snow is possible up top Saturday.
The warmer system moves out after midnight and the colder system off the CA coast moves inland Sunday through Monday. That will bring in colder air early Sunday with snow levels dropping close to the base by Sunday morning. That means that 1-3″ of wet snow is possible to the Palisades Village by Sunday morning, with 4-12″ possible overnight on the mountain from bottom to top as snow levels fall.
Snow of varying intensity is possible for Sunday with snow levels falling below the base during the day. Ridgetop winds still gusting up to 70-80+ mph at times, which means another day of wind holds likely. Highs in the 30s at the base and 20s up top. Several more inches of snow could fall during the day with the snow becoming drier.
Sunday night into Monday the snow showers are expected to become more scattered and lighter. The winds come down Monday but could still gust up to 30-40+ mph from the west. In total Sunday through Monday, we could see an additional 6-10″ at the base and 9-20 inches on the mountain.
Storm totals could be around 7-13 inches at the base and 13-32 inches on the mountain from bottom to top by Tuesday morning. A large snowfall range than normally forecast for a storm but that’s what happens when we start with rain and then have falling snow levels throughout the storm. A lot more snow falls where it stays all snow vs where it turns to snow last.
Tuesday – Thursday:
We should see mostly sunny skies Tuesday through Thursday and cold with highs in the 30s at the base and 20s on the upper mountain. We should see lighter winds, at least through Wednesday.
The next storm could move into northern CA around Friday the 9th into Saturday the 10th. We’ll continue to watch the trends with this storm as we get closer.
