Watching rain come out of the Arizona summer sky

Here is a sequence of photos showing the development of a rainshaft from a prior “doing nothing” cloud base.  For a long time, it appeared that these dark clouds, bottoms of Cumulus clouds, were too raggedy, not contiguous enough in a nice, large and dark region indicating a wide updraft, one  that might push cloud… Continue reading Watching rain come out of the Arizona summer sky

Kind of sad today.  Too sad to think of a title.  Thought you’d like to know that.  Yesterday was once so promising.  I almost had it all.   I was SO happy to see clouds topping Mt.
