High Sierra Topix

I did this trip in July. I loved it and want to do it again & have time off in May. I'm just starting to consider this hike at this time. Does anyone know what the weather/snow conditions are historically? Also does the shuttle run that early in the season?

In July I parked at the mammoth ski area & took the shuttle to agnew are starting point. Day 1 hiked the high trail to thousand island. Day 2 hiked to Ediza via the JMT. Day 3 hiked to minerat by going XC through iceberg & cecile dropping down into minerat. Day 3 hiked out to soda springs catching the shuttle back up to the ski area. Beautiful hike but even in July there was snow around iceberg/cecile. That stretch was tough. The boulder part up from iceberg to cecile had no snow & would surely be a different (more difficult) with snow there as well.

Any and all opinions & comments appreciated.

Thanks

This is easy, roads will be snowed in, of coarse no shuttle.
Several feet of snow, all lakes still frozen.

lol Guess ill try to plan it later.

Thanks,
