Snow levels are forecast to start at 7,000′ on Sunday before crashing down as low as 3,000′ on Sunday night.

Snow levels will be around 7000 feet during the day on Sunday,
with snow mainly affecting the passes around Tahoe. 

Around 4 PM, snow levels crash down to Lake Tahoe level and down
to valley floors in western Nevada by 10PM Sunday night. Now this
is a precipitous drop in snow levels, an impressive 3000 feet
lower within 6 hours.

NOAA is talking about the potential of some very big snowfall totals on Sunday:

Our best estimates for snow totals will be around 4-8" around the
Lake Tahoe Basin (6000-7000ft), with up to 1 to 2+ feet above
7000 feet. If snow levels fall quicker than anticipated, those
numbers could be doubled. 

Snow amounts will be less in Mono County as the storm system
loses much of it`s punch as it moves south. - NOAA Reno, NV today
