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

Peachy!
Sunset, anyway, even if only a few drops of rain fell last evening. Nice lightning to the south, too, 9-10 PM. However, yesterday afternoon, we had some examples of really “bad” cloud bases. They were trying to make me think we might have a repeat of the day before’s cloudburst by darkening themselves up.… Continue reading Peachy!
Yesterday’s Catalina-centered blast dump: 0.83 inches; 0.53 in 16 minutes
Nice weather we’re having lately. Nice desert greening we’re having now, too. What a day yesterday was! Look at the sunrise view of Altocumulus at the start of the day. And, too, how about some neat patterns before all the mayhem. What a day, to repeat. Yesterday’s blast and dump that struck just after… Continue reading Yesterday’s Catalina-centered blast dump: 0.83 inches; 0.53 in 16 minutes
“Back in Black”, cloud bases, that is
Few people know that Angus Young, lead singer for AC/DC, was quite the weather nut and many of his songs, such as “Back in Black”, are actually about clouds and storms. Thought you’d like to know so that when you get your old AC/DC albums out, they’ll have a little more meaning to them… What… Continue reading “Back in Black”, cloud bases, that is
Lenticularis in July?
Altocumulus lenticularis, to be exact. Of course, as the discerning, eruditeful cloud person that you have become, I didn’t need to tell you this. Well, yep, here they are, courtesy of the U of A Wildcats website. And, if you missed them locally near Catalina, here are a coupla shots. In this movie, you… Continue reading Lenticularis in July?

Since they are open today, Saturday, it would be great if you went down and… Continue reading Catalina summer rainfall 1977-2010: there is no trend
Defining the Catalina summer rain season
catalina summer rain profile The data here are almost all due to those nice folks, Jenny and Wayne, down at Our Garden right here in Catalina, who meticulously kept weather records beginning in 1977. Thank you, Jenny and Wayne! The End.
“This (dry air) will not stand”
Pretty tough day, yesterday. After a few altocumulus floccus shred clouds around dawn until around 7 AM, the sky became absolutely, totally clear. Once again, I did not expect this. (There are a lot of surprises in life when you are a weather forecaster.) I thought shirley1 a few small Cumulus would form later that… Continue reading “This (dry air) will not stand”
“Groundhog Day” all over again
If you mainly focus on going to movies about weathermen, you will remember this classic along with Steve Martin’s “LA Story.” Bill Murray, the weatherman, is condemned to live the same day over and over again until he gets it right. Since yesterday was a near repeat in many respects to the failed rain… Continue reading “Groundhog Day” all over again

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. Lemmon at dawn, and then later, cloud bases down on Samaniego Ridge east of Catalina. How warm those… Continue reading Untitled
