It rained the morning of the 27th but the data fell out there :-p It has been
cloudy and maybe a "few drops" but nothing else significant.

The Q1 dip should be real. There is an instant local temperature dip that is
probably the computer crashing (there is no file so it read as zero) but Q1 and
the pinger data should be fine. I would guess we had a little spot rain around
that time.

I am thinking of adding a top terminal next. Maybe this afternoon since the
weather looks "dull".
