Hey Bengator,
According to the rangers at Lone Pine, Langley got dusted significantly last week (about 6 inches they said), but I'm not sure how good their info was - their reports about Mt. Whitney proved to be a bit pessimistic. But, from our hike up Whitney on Monday, we could definitely see snow on Langley... Hard to say if it was passable or not...
I'd bet you could get pretty far up though, before you hit much snow...
Take it easy
