Oh, well. When you’re sloppy and asleep at the wheel, think you know more that you really do, that’s what happens, “weather surprises” that shouldn’t be.
But, what a gorgeous day again! Really, with the smoky skies gone I am so appreciating a blue sky pocked with Cumulus and Cumulonimbus clouds!
Lettuce reprise yesterday in all its unexpected glory:
Since I was clueless yesterday, will remain quiet about today’s weather, though we do have low level moisture around as clouds are again topping the Cat Mountains.
We’ll still get into some early winter like weather in only a week–that’s pretty much in the bag. Probably no rain, though, just a bit of a very windy day or two and very cold air for the time of year plopping over us. Our TEEVEE weather folks are surely all over this!
We’ve waited a LONG time for a rain day. It was so nice, so photogenic as well. I hope you enjoyed it as much as I did.
Also, you may have seen the Froude Number1 in action as Cumulus congestus and Cumulonimbus clouds developed and went around the sides of the Catalina Mountains instead of developing over them and dumping big shafts of rain on them. The heaviest rains yesterday were due to streamers of showers and with an OCNL TSTMS that were north and south of us, Oracleville, Bio2 area, and Marana, Avra Valley where over half an inch was logged in some places.
Still , we managed a third of an inch here in Sutherland Heights, the first appreciable rain since I don’t know when, though, I could look it up. Too long, though, even for Catalina.

Except for a morning or afternoon sprinkle, no rain in sight, just a warm up back to above average temperatures. Dang.
1The young fluid dynamicist, Richard Penniman, fascinated by the flow around mountains, and who later became known as the rock and R&B entertainer, “Little Richard”, first brought the Froude Number to public attention in his song, “Tutti Froude-e.” The title, after an early release failed to capture the public’s imagination, was later revised for greater “accessibility”, to the song we know today as, “Tutti Frutti.”
2Who can forget “Max and the Storm Troopers” and that great song? I would submit, “everyone.” Of course, few know that after 1968 they changed their name to “Led Zeppelin.” And that, my friends, is “the rest of the story”, as Paul Harvey might say if he was lying about something anyway.
“Too many pictures, for one site…”, a continuing theme here1, to paraphrase “? and the Mysterians1“.
Two stations near Picture Rocks reported 1.25 and 1.35 inches, respectively, so some major rain fell fairly close to us. You can see the amount arounds around the State or here at the Banner U of AZ rainlog,org site.
Below your October 8th, 2016 cloud day, a Saturday in which the author’s former company fubball team, the Washington Huskies, spanked the Nike University of Oregon Duck, 70-21, ending years of futility against the billionaire’s sports teams. Too bad Washington multi-billionaire Gates is more interested in saving the world instead of helping the Huskies get better in sports like Phil Knight does with The Duck there in Duckville, OR….
Oh, well, off task there for a minute. I’m back now!
Now, here where the excitement begins. Recall Mike L. and Bobby Maddox, both super experts concerning convection, called for severe storms and large hail today due to what the models were showing in the vertical wind profile and the amount of moisture available. Below, we start yesterday chapter of convection, and see where it leads.
1If you don’t believe ? said something like that, go here
Kind of getting tired of gorgeous rainbows every day, ones without a lot of rain here in The Heights. But, here they are again:
Upwind Cumulonimbus clouds faded as the trudged toward Catalinaland yesterday, bottoms evaporating, raining out, leaving only a big patch Altostratus cumulonimbogenitus way up (at least ten kft above the ground) there with rain drops just big enough to survive evaporation and reach the ground just before 3 PM.
In the meantime, all the excitement, possibly spurred by the gusty outflow winds that accompanied the above seen, was happening almost overhead to the NW-NE, as a great line of Cumulus bases blackened. They were already passed us, but if they unloaded and sent a pulse of wind out and toward us, then we might end up in a wind clash zone, with huge clouds forming overhead. OK, was dreaming again, but here’s what was going on, which ultimately led to another major dump on the CDO watershed.
Hiked over to see if the Sutherland Wash, east of the similarly named housing development, Sutherland Heights, had a good flow from our “Mighty Kong” of prior day. It had:
The weather ahead
Seems Remnant Roslyn will spit out another snippet of moisture ahead of our fall-like cold front passage late Sunday or early Monday bringing clouds, and with clouds, a slight chance of measurable rain. Don’t hold your breath for measurable rain IMO. Hope I’m as wrong as the prediction I made to a friend that the Stanford Cardinal would trounce the wildly overrated Washington Huskies fubball team last night.
Should be some good rain today in Catalina, FINALLY! Thinking maybe half an inch or so over the next 24 h, something decent, as tropical air drains o northward and over us out of tropical storm remnant, Roslyn (“Rozzi”).
Clouds and weather interruption:
Due to the name of our weather-affecting tropical storm, Roslyn, I am now reminded of a profound, life-altering “Hallmarky” chapter of life when I was in HS, involving another Roslyn (aka, “Rozzi”). In an another attempt to increase blog readers, those really not interested in clouds and weather anyway, I have inserted this story about a 15-year old, shy boy and his incapacitating crush on a Rozzi R as a junior in HS I suspect it is a fairly common one in some ways, although this one leads to the formation of other people with a different classmate. The Story of Rozzi R
This story was passed to Rozzi, who had no idea who I was, only in 2009, btw. She seemed to like it, and told me about her life, family and three kids. I think its OK to share it.
Back to weather, at 7:11 AM, one pulse of rain is within a half an hour or so. (Later, we only got sprinkles out of that first pulse).
Nice rainbow last evening; nice sunset, too:
The Prodigal Storm yesterday afternoon
Yesterday afternoon had quite the dump and something of a little ‘boob from the outflow winds, so much rain came down initially around Oro Valley/Marana, west Tucson, south of Pusch Ridge. Was heading this way, too, with nice big, black, solid-looking base. Started a video of it, thinking about the gush was to strike Sutherland Heights/Catalina.
Here it is, in all of its glory and subsequent dissipation:
Models, with spaghetti support, show a strong, but dry, cold front coming through next week, and fall will be in the air as nighttime lows drop into the 40s in our colder, lower spots, like at the bottom of Catalina State Park, in the CDO wash, etc.
Welcome to one of the great cloud blogs of our time today, great as in volume, not in eloquence or anything like that.
A humorous final note: Here are two model runs only 6 h apart from last evening. The first one, from 5 PM AST global data, valid on the 26th, brings that Mexican Pacific hurricane back into AZ/NM as that strong low drops down into Cal! How crazy izzat?
The second panel was the model output from just 6 h later for about the same time. No trough nowhere near Cal as is shown in the first panel, and our powerful hurricane stays well offshore. Still, it was an intriguing glitch of a magnitude you hardly ever see.
Also, I am also posting way below a new (!) not-previously-published. but rather rejected- by-important-scientists-a-long-time-ago-manuscript FYI!
Very exciting! (Hah!)
Its published now, though, isn’t it???!!!
Its about science and how it works, and how it has failed; examples given. I put it down toward the bottom of a normal blog because I am shy.
Clouds from a few days ago, August 26th, now that the “choke point” in uploading photos to Word Press has been, at least temporarily ameliorated.
Here’s the sequence as a great cloud bottom drifted toward us from Pusch Ridge on the afternoon of the 26th. If you saw this coming, you should have been clearing channels around the house for excessive water flow. I forgot to.
Unloaded 0.45 inches at this site. 1.69 inches up on there on ol’ lady Lemmon. We sure needed this dump! Below, one of the great cloud bottoms of our time, that of a Cumulus congestus cloud, filled, as we say here, with rainy portent (maybe hail, too):
Pedagogical or possibly, pedantic (boring) module
Update alert for the posting of new (!) not-published rejected items by this Arthur:
(the original title, submitted first in 1997), final rejection in 1999 (Bull. Amer. Meteor. Soc.)
The reviewers, Harold O., Danny R., and someone named “Anonymous Reviewer B”, guessed as, “”B”, for “Bernie S.”
Those in the cloud seeding culture don’t need the names spelled out. Harold O. is part of the “old guard” cloud seeding culture, while Danny R. is part of the new cloud seeding guard, one that has gone on to be a science superstar since his early work at the Hebrew University of Jerusalem under the leader of the Israeli cloud seeding experiments. He did some work there on the clouds of the Mediterranean and satellite interpretations of them (available in Hebrew only the last time I checked).
While Danny R was there during the time of the reporting of the benchmark Israeli 2 randomized experiment by the leader of the experiment (1976-1986) he himself was not involved in those (ultimately flawed) analyses. Later, he participated in the unraveling of the 2nd experiment with Israeli statistician, K. Ruben Gabriel in 1990, J. Appl. Meteor. Half of the 2nd experiment’s results had been previously omitted, an omission which produced an apparent, unambiguous “confirmatory” success of the Israeli 1 experiment, for the short of it.
The 1990 development in Israel, in essence a retraction of what everyone thought was an unambiguous cloud seeding success, plus the fall of the equally important, earlier benchmark randomized experiments in Colorado, at one time also claimed to have proved cloud seeding by the National Academy of Sciences (Malone et al 1973), were the primary reasons for composing the piece being posted today. You may also know that your very own Catalina “cloud-maven” was in Israel in 1986 for 11 weeks, in doubt of those “hard-to-rain” clouds that were being described by the leader of those experiments, resulting in “Rain from Clouds with Tops Warmer than -10° C in Israel”, (1988, Quart J. Roy. Meteor. Soc.). This was to some degree the first crack in those experiments. (Of course, I would say that!)
How could such glowing, but ultimately critically flawed journal papers appear ultimately involving hundreds of journal pages? What went wrong with peer reviews?
I attempt in this piece to describe in this piece how science is supposed to work, and these pretty amazing chapters of science in cloud seeding, and offered some possible solutions.
At one time, Prof. Peter V. Hobbs, named to write up a status piece on Clouds-Climate for the World Meteorological Organization (WMO) in 2003 or so, was going to use the “rise and fall” of the Colorado and Israeli experiments in this piece I have just posted. He was going to demonstrate how we scientists can think we have proved something, but upon closer inspection, find that we have not proved at all!
Peter Hobbs was concerned that the then many unknowns about clouds were not being treated properly in climate models (being parameterized too crudely), and therefore those parameterizations of clouds in climate models could lead to erroneous conclusions concerning the amount of global warming that might be ahead.
In his take on this MS, and that “rise and fall” section in particular, Peter, who was not one to dole out compliments very often said of it, “This is pretty good.” Peter had not reviewed it beforehand.
Ultimately, Peter contracted pancreatic cancer and was unable to submit his status summary to the WMO.
