All these storms will start with high snow levels before those snow levels drop as low as 6,500′ by Sunday night (see below).  

All these storms will be absolutely dumping snow on 14,172′ Mt. Shasta, CA (photo below from last Tuesday).

20-46″ of snow are forecast for Mt. Shasta between now and Friday and we’re confident a lot of snow fell on Shasta last night/this morning.

The crew from Mount Shasta Guides was skiing 3,500-foot powder runs on a base of 5-7 feet of snow last week after the huge Atmospheric River storm that clobbered CA, OR, & WA October 13-16th, 2016.

Tahoe will be seeing snow mostly above 10,000-feet to start the week before snow levels drop as low as 6,500′ by Sunday night.

That same Atmospheric Storm cycle added 11 billion gallons of water to Lake Tahoe, CA and raised its water level be 3.33″.

WHAT NOAA IS SAYING ABOUT TAHOE SNOWFALL:

TODAY:

Snow levels remain high and generally in the 7,500-
8,000` range across the central Sierra with mainly just wet roadways
evident on roadway cams through the Sierra.  
- NOAA Reno, NV today

THURSDAY:

The warm subtropical trajectory of this system will result in very
high snow levels (~10,000`) and will likely be mostly a rain maker
except for the very highest peaks.
- NOAA Reno, NV today

WEEKEND:

This storm looks a bit colder with snow levels
starting around 8500 feet on Saturday, then falling to near 6500
feet by Sunday night.

"After a couple of small systems with limited moisture move through the region early this week, a wetter system will move into the Sierra late Thursday into Friday. Its trajectory and subtropical nature will result in higher precipitation efficiency as well as very high snow levels from 9,500 to 11,000 feet based on current projections. Consequently, there will be quite a bit of spill-over into Western Nevada which is usually rain-shadowed. " - NOAA Reno, NV today
