I want to start planning for my June 15th hike, and I would love to know whether I should bring snow gear, warm clothes, or just light weight clothes (like the last time we summited).

Last time, I had 28lbs in my pack at start and 22lbs when I got back down, and I wished I had not taken a lot of cold weather gear up and back down.

Are there reliable sites with trip reports or weather reports?
