Observing Summary:

Cloud at start, dissipated fairly quickly until I could open 
around 9:30. About 2 hours later, the humidity came up so
I closed.  By about 2:30 the humidity was (just) below the 
limit, so I opened again until twilight. Kitt Peak stayed closed;
their gauges did show dropping humidity, though.  I did manage to
finish up on at least one target.
