Not nearly as deep, but the Sierra should have lots of snow this summer. Reference https://www.nps.gov/lavo/planyourvisit/fourth-of-july-weeken...

Edit, looks like your sierra ref is mostly about Lassen which is not really the sierras but an old volcano n.west of them.
Very frustrating not being able to ski because of too much snow!
The tendency for what snow we do get to blow off elsewhere is why ski areas in Scotland have huge amounts of snow fencing (they are all above the treeline) to try and trap the snow in place.
