Humidity came on strong at first, paused, and then by 11:00 pm MST was growing perilously high. Performed an early shutdown. Around 1:30 am MST humidity levels dropped enough to reopen the domes. However, at 4:00 am levels rose again (and we also had to leave the mountain). ------------------------------ Submitted on 2015 May 4 [4:14:05]
