Observing Summary:

Huge monsoon storm yesterday afternoon with hail (!), but
conditions moderated by sunset and finally it cleared off 
pretty well around 11 PM and we opened.  Got a good five-hour
interval of mostly clear weather, which we put to productive
use. Before twilight clouds started appearing and the overcast
was total by 4 AM, 15 minutes after twilight began, so we closed.

There's lightning far to the E that may get here before the staff
arrives for the day, so did a lightning shutdown before
heading off for bed.
