No NWS sounding from the U of AZ Weather Department yesterday afternoon, so’s we can’t really tell with solid data what the temperatures of yesterday’s frosty clouds were. However, with a max here in the Heights of Sutherland of 71°F, and with a dry adiabatic lapse rate to the bottoms of the clouds (as is… Continue reading Frosty the Cumulus cloud

Drizzle and Stratocumulus bonanza
No, this is not about Bonanza, the TEEVEE show, “Hoss”, or any of those ranching people, though that might be more interesting than a blog about clouds, gray ones. First of all, the word, “bonanza” would be capitalized (its not on my view of this edit, FYI) if this was a blog about it. Second,… Continue reading Drizzle and Stratocumulus bonanza
Last of the Cumulonimbus
Last call for Cumulus clouds today, maybe a distant Cumulonimbus top off to the north. Then one of those long clear and dry spells of fall gets underway…. The End
Wintertime cold Cumulonimbus clouds erupt with sprinkles and snow flurries; no damage reported
One passed over at 9:19 AM with a hard multi-second, surprise rain shower. One person reported a couple of graupel, or soft hail particles. Tipped the bucket, too; 0.01 added to our Sutherland Heights storm total. Its now at 0.23 inches. Of course, there was no damage, but putting that word in a title might… Continue reading Wintertime cold Cumulonimbus clouds erupt with sprinkles and snow flurries; no damage reported
Sutherland Heights storm total now 0.71 inches as of 7 AM; soil turning green as moss look alike growth reminding one of Seattle spurts from bare ground!
First, in blogging for dollars, this: Here’s a nice one from the day before as the clouds rolled in, starting with Cirrus and Altocumulus, lowering to Stratocumulus later in the afternoon. Yesterday’s clouds; an extraordinary day with a little drizzle amid light showers Hope you noticed the true drizzle that occurred yesterday, namely, fine (larger… Continue reading Sutherland Heights storm total now 0.71 inches as of 7 AM; soil turning green as moss look alike growth reminding one of Seattle spurts from bare ground!
An unbelievably long blog about a surprise afternoon sprinkle of rain
A very few small, isolated drops fell between 4:50 and 5 PM here in Sutherland Heights from what appeared to be nothing overhead. You’d have to be really good to have not been driving, and to have anticipated the possibility (by recognizing ice in upwind clouds) and then having observed it. You would be recognized,… Continue reading An unbelievably long blog about a surprise afternoon sprinkle of rain
Evening thunderstorms roll across Catalina with apocalyptic cloud scenes
Some apocalyptic cloud scenes can be Cumulus that explode suddenly into Cumulonimbus, and Cumulonimbus clouds with their foreboding (unless you live in a desert) rain shafts, and their predecessor shelf clouds like “swirly dark Stratocumulus”, and arcus clouds, the latter, a lower line of clouds just above and a little behind the wind shift at… Continue reading Evening thunderstorms roll across Catalina with apocalyptic cloud scenes
Passages: an upper low one on the 18th disappoints; today is the 20th
I got behind…. Lot of great scenes on the 18th, but, ultimately with hopes raised for appreciable measurable rain in Catalina, it was a disappointing day. Nice temperatures, though, for May if you’re a temperature person. Only a sprinkle fell (4:15 PM), and if you weren’t outside walking the dogs you would NEVER have noticed… Continue reading Passages: an upper low one on the 18th disappoints; today is the 20th
One of the great humilis days of our time; began with virga above Ms. Mt. Lemmon
I was really happy for everyone out there when the skies were dotted with so many perfect examples of Cumulus humilis. It was like a numismatist finding a perfect Indian head penny. If you were like me, and I suspect you are, you were just going CRAZY taking pictures of those flat little pancake clouds. … Continue reading One of the great humilis days of our time; began with virga above Ms. Mt.

I. Q. Test (“Ice Q”, that is)
Yesterday was a great day both for airborne researchers studying the onset of ice in clouds, and for my followers to test their “ice” Q detecting abilities, to come up with a clever play on words there. What was so great about yesterday’s clouds? Well, they were real cold, bases up around 9,000 feet above… Continue reading I. Q. Test (“Ice Q”, that is)
