You are better off heading up Baldy, Jacinto, or Gorgonio if you want to snowshoe.
From where I live, NO SNOW on the local peaks from my kitchen window. This time last year was a different scenario.
The weather forecast up here is....DRY.
Tioga Pass is open....rare for this in December!
If you plan to come up, bring a fishing pole cuz there ain't much else to do but HIKE!
