You can get snow in April, we have had up to 8 inches. But not very often, and at least at our elevation, 7300ft, it has always melted the same day.
The drive down into the valley is pretty steep with a couple of sharp turns, so go slow and be careful with the brakes.
It is a very pretty drive, but I usually avoid it if I am trying to get somewhere since it is a slow drive.
