I have been in Arizona since Sept of 1974 my first 5 years in this State
just about every month new moon weekends were a go. Even Jan and Feb. The
monsoon of August 1975 almost was non existant. I could not figure out what
people were talking about. But as I mentioned seems like the weather changed
for the worse around 1978 and thereafter. Some years being pretty good and
others down right not fun for Astronomy :(

Tom,
Irrespective of what the data shows with regard to clouds, it has been
extremely windy this past month, more so than usual. Other residents
here have noticed the same thing. April has never been this windy, and
cold (not all areas are equally affected by global warming, and besides,
recent research discovered we won't feel the real impacts of global
warming for about 10 years). Even if the skies are clear, you would not
be able to observe as most amateurs do because it is just too windy.
Even with an observatory with a dome, like I have, it is not much fun
when the wind is not only strong, but cold.
