I was hiking on that same day. I made it to the summit at 11:30 ish. I didn’t spend much time up there other than pictures and signing the book. On the way back down it started to snow. By the time I hit the switchbacks it was just a light sprinkle. I couldn’t believe how many people were still ascending the switchbacks in attempt to summit with the weather being like it was. When I got back to Trail camp some campers told me the we’re hearing thunder but while hiking I never heard anything. Also we had a bear steal some food from my group while getting ready at the portal @1:30am.
