Well it's certainly looking a lot like winter for the rest of the week !! It's possible that the high points along Tioga pass could see 5 foot of snow accumulation laying on the ground by Sunday evening ! With heavy snow and winds gusting up to 50mph along crests and through canyons it sounds pretty treacherous out !
It's just the beginning of this batch of winter weather and already the 'Hump' is starting to show in the bottom right of this picture from the High Sierra webcam.
