In the Baldy area, I went up Icehouse Canyon and did not reach the snow until about 3 miles up. Problem is you would need snow gear to sleep up there as it gets icy early and late in the day and the trails are steep. There may still be good snow up in San Jacinto within a couple miles of the arial tram, but I havent checked. that's another hour out for you though. You may have to wait for another decent snow.
Oh wait, Big Bear might be the place if you go quick. the snow is very thin but its there.
