Now for some disappointing weather and cloud talk…
Well, not much rain, anyway, just 0.04 hundredths here. Nice to see, though. For a time it looked like we were going to get fully shafted by that complex coming over Sam (Samaniego) Ridge around 5:30 PM AST.
On the one hand. we got to enjoy plenty of thunder and some big booms a few times, on the other, an OK rainbow as the rain crept closer on lion’s feet, some gusty winds, 25-35 mph, that blew stuff around, and on a fourth hand, an OK summer rain season sunset.
But let us begin by going back to Sunday for a moment and view an interesting contrail, an old one that looks like a version of CIrrus uncinus.
U of AZ WRF-GOOFUS mod doesn’t think a shower will happen for another couple of days. Since we have Ac cas this morning, I am looking askance at that output, hoping its dead wrong!
What about the haze? Where’s it coming from and its awful! And its here again today. Reminds one who lived in southern California of summer skies in southern California, hazy, whitish, the orange- colored sunsets that people sometimes thought were “so pretty” but they were ugly because they were orange because of smoke and smog and s like that.
Where’s it coming from, to repeat? Not sure. But see back trajectories below.
These suggest its coming from the east in the last day or so of the trajectories. The trajectories start high up because we’re in the descending air branch of an upper air anti-cyclone that’s dessicating the air, preventing even little baby Cumulus from forming.
Lidia’s moisture will help some, but it appears no rain will reach us today, Dang.
But things get more promising for at least a short return of the summer rain season (remember, the real monsoon is in India) in the immediate days ahead, phrasingly vague enough to insure a great forecast verfication! haha
Looks across Catalina and Oro Valley toward the Twin Peaks area yesterday afternoon. “Egad”, to repeat a mild expletive.
Giant homework assignments (i.e., controversial cloud seeding manuscripts for journals) seem to go on and on, and so can’t really talk clouds and stuff so much, with all the usual obligations of living (e.g., like vacuuming, washing windows, pulling some weeds, but not too many for habitat saving purposes, removing a pernicious, spreading hybrid cactus with microscopic glockets, akin to growing your own asbestos, and preparing a home we used to live in here in Catalinaland for sale). Perhaps you’d like to make a HUGE offer on it… That would be great! Thanks in advance for making a HUGE offer! Its where I started blogging, so there is that bit of historicity. haha
From yesterday evening, these:
Seems like another dry day today, though with “Cumulonims” here and there. Rain chances pick up as we close out the month. Way behind average for August; now at only 1.10 inches here in The Heights of Sutherland. Average is 3.36 inches, our wettest month.
In neighborhood news….
Below, the saga of the tortoise. I parked and waited for him/her to get across Equestrian Trail Road. There was a small rise in the road from where he was and someone in a hurry would have smashed him flat. This is who I am and why I write controversial papers about cloud seeding. Some do gooder has to do it, even though in the latter case you become a persona non grata in your specialty, your work isn’t cited when it should be by “scientists” who know about it, etc. Back to torti….
Wonder if anyone out there saw that “The Desert Speaks” program on PBS two nights ago where there was a herpotologist that spent many nights patrolling roads to get critters off the road so that they don’t get squashed. What a guy; a hero really! I think I could do that if I wasn’t so cloud-centric.
Not much going on lately, so will dip into the archives from two days ago. One cloud in particular was so spectacular in its defiance of gravity, rocketing upward the morning of the 4th. So here are shots from that day…
6:46 AM, Aug. 4: The day began with a pretty normal looking patch of Altocumulus perlucidus (honey-comb pattern). No virga, so its likely not too cold. The sounding suggests it was up at 16,000 feet ASL, or 13 kft above Catalina at about 0°C (32 F).
Now, that’s pretty funny. We specialize here in too much said! Its a niche thing. Of course, not enough can be said about our past July. Take a look:
This, of course, was a new July rainfall record for Catalina/Sutherland Heights going back to 1977, anyway. Had to adjust vertical axis of this chart, too. Formerly, it stopped at only FOUR inches! The moon lore was right! It’s interesting how the ancient lore of early peoples that I made up a month ago was more accurate than the Climate Prediction Center’s prediction of an equal chance of above or below normal rain in southern Arizona while something incredible was on the doorstep! Kind of like last winter in the whole West where record amounts of snow and rain piled up over a huge region, and that, too, was also unforeseen “going in.” Think how horrible it would be if those predictions were always right. Sure, billions could be saved by such accurate outlooks, but then the element of surprise would be gone. How bad would that be?
After the paucity of rain in the preceding five months, and with June carrying into around July 10th this year with its blazing heat and no clouds, all that rain that followed with thunderations day after day, the attendant rain-cooled “breezes” to 50 mph on occasions, blowing stuff all around everywhere, were sure welcomed (?). (Another case of innovative punctuation to emphasize a point, whatever it is.)
Let us begin today by examining the greenth of the 2017 summer on our Catalina Mountains so far, thanks to July’s copious rains. Hah! The climate really has changed. Looking into growing bananas now…Now for some cloud photos from yesterday:
Well, the day closed on a disappointing note as Cumulonimbus debris clouds overspread the sky, killing new convection.
The weather way ahead
Looks like below average rain for August. :(, as we say. Hoping for error here. Average August rainfall here in Catalina/Sutherland Heights is 3.16 inches.
“Frog strangler”, folk expression from the South for extra heavy rains, btw, which is what we had, except we have toads, not frogs.
Here’s what I think happened to produce 3.36 inches on Sutherland Heights. The winds were from the east at cloud levels. Cumulus spawned off the Catalinas/Mt Lemmon area, but the wind shear brought the tops over Sutherland Heights about the time they got cold enough to form ice, yesterday around -5° to -10°C (higher than the usual temps for ice formation because the cloud bases were so warm. I know what you’re thinking, “huh?” Take my word for it, that’s the way it works; the warmer the bottom of a cloud, the higher the temperature at which ice forms in it. Of course, over the oceans cloud base temperature doesn’t make that much difference… I better quit here on that.
Where was I? Oh… So, leaning out from the mountains is where they began to dump their loads beginning in mid-morning, when updrafts were likely modest. The first one missed Sutherland Heights altogether (except for a sprinkle, but drenched Oracle Road and the Basha’s area. And, likely because it didn’t rain on the east side of the Catalinas until later, those monster turrets kept spawning upwind of us.
The second in this series was a stronger turret, one that could stand more upright against the wind shear and dropped its load on Sutherland Heights. Indicative of stronger updrafts in that one was the onset of thunder, first aloft, then in ensuing turrets shooting upward, increasing cloud-to-ground strokes until it was unsafe to go outside without the thought of being fried.
And of course, the rainrates picked up, and stayed that way as new turrets launched off the same zone of the Catalina Mountains through mid-afternoon. That in itself was remarkable, and if you looked around, you could see that it wasn’t raining all that much either to the north or south of Catalina, and that the rainshafts faded as they trekked across Oro Valley.
The net result, an incredulous 3.36 inches here (3.37 inches in NWS-style gauge here), bound to raise eyebrows concerning possible rain gauge fraud; nothing like it anywhere in the local area! The ALERT gauge on the Golder Ranch Bridge only had 1.46 inches and Samaniego Peak, 1.93 inches! There will be very few days in our lifetimes like yesterday. Go to rainlog.org to see how amazing our local amount was in comparison to other gauges, once again raising the specter of fraud due to an outlandish amount1.
And, again, it was closer to what a REAL monsoon day in India, say, at Cherrapunji, where passing heavy rains are accompanied by the occasional thunderclap. So, in a sense, yesterday you were climatically transported to a land faraway, where tree roots are so big they make bridges out of them…
Some photos of this event, well, too many, really, after all, too many cloud photos is our niche!:
The End, of a very hurriedly thrown together piece. Got actual work that must be completed soon, something if you read it, it would be so boring you’d want to shoot yourself before you finished it! Sciency stuff. Oh, well, nose to grindstone now.
Later yesterday morning, some interesting “Altocumulocirrus”, a rare breed indeed, mocking/mimicking Altocumulus.
Maybe Cirrus floccus would come closest to the true name, but to every eye but that of a genuine cloud maven person, it would be deemed just “Altocumulus”. Check these out to see how good you were–and NO correcting your cloud diaries!!!!
Haha, most readers won’t even notice! But maybe some cow-centric, instead of cloud-centric, folks will drop by, raising the worth of this blog to above $35 if sold….that according to a “biz” site.
Had a rainbow yesterday. Hope you noticed. It was pretty early and overhead west. I think the clouds did not have ice in them. The rain echoes were not showing up on the radar, suggesting the beam went over the tops. Sounding suggested tops might have been as cool as -5°C. In any case, the drops were able to tip the bucket a couple of more times, and along with yesterday afternoon’s brief, light rain showers our total has climbed to 0.37 inches for the storm. Not bad, though as in money, you always want more.
These storm breakup days are always our prettiest, and that’s often what this site is about, being pretty. Yesterday had some fabulous scenes; couldn’t stop shuttering cam. It is a real neurotic compulsive behavior pattern, as afflicts some of us cloud and storm-centric folk. Check Mr. Olbinsky’s work; his work goes beyond phenomenal whether you want a wedding photographer or want to see a storm chasing video. But it takes that kind of eccentric energy to be special, to stand out as he does.
Here, though, we let the storms and cloud scenes, such as they are, hope for the best, and let them come to us…. Kind of a lazy storm chaser’s attitude.
Still cold aloft, so having some nice Cumulus today is in the bag, the early Stratocumulus devolving into Cu, that is.
At this hour, a small, pin-wheeling, galaxy-like vortex is drifting toward Catalina. Last night the town was ravaged by 0.30 inches of rain and winds to 50 mph around 2 AM as one of its pin-wheeling bands came through, likely with a big arcus cloud fronting it.
This was the first measurable rain in Catalina since I don’t know when. You probably don’t remember, either, its been that long.
More rain is expected as the little pin-wheeling vortex moves overhead of the little village of Catalina today and on to New Mexico tomorrow.
Plunked below is the Pima County ALERT rain map amounts with the Sutherland Heights amount plunked on it as well. We did pretty well it appears, compared to surrounding amounts. Yay. Our desert will love this! The greatest amount here is 0.46 inches at Dan Saddle in the CDO upper watershed. I guess he hasn’t found it yet.
And if you mention our desert vegetation, as I have, how can you not exult over the fabulous blooms on one of the most horrible plants on earth (haha), as far as spines and glockets go, the prickly pear!
The Weather Way Ahead
Our models, supported by those ensemble “spaghetti” maps are making most of May look pretty darn nice, at least through 20th-25th as the upper air configuration reprises troughs twixt now and then. They’re looking like dry cool fronts, though, no rain in ’em. Snowbirds done left too soon!
