The storm: what about it? Its here, such as it is. Stations upwind of Catalina and in the approaching rain band have been reporting about a quarter to one third of an inch this early morning in light to moderate rain. Seems that’s the most likely total here now, though our best model, from the… Continue reading Yesterday’s dust before the storm

Creepy Stratus fractus
Well, that cloud WAS “creeping” toward us after suddenly appearing on Pusch Ridge at dawn… Looky here: ———– With Halloween only 10 and half months away, I thought I would “get in the mood” and make up a little creepy-ness for the little kids who read this blog. Hi, kids! Hope you didn’t get… Continue reading Creepy Stratus fractus
Yesterday’s drizzle
Some rare drizzle precip1 fell yesterday. Suggests clouds were pretty “clean”, that is, didn’t have much aerosol loading and the concentrations of droplets in them was low (likely less than 100 cm-3) Also likely, in view of the recent strong winds, some of the aerosols in those clouds might have been large dust particles2 rather… Continue reading Yesterday’s drizzle
The trace
We had a trace yesterday in SH. There was not ONE but TWO periods of rain, the first at 1236 to 1237, and the second from 1240 to 1240:30, both from the same cloud, but likely from different turrets protruding above the base. The drops were very small, barely mm-size, with considerably horizontal separation between… Continue reading The trace
Canadian dreams
Note: Images did not show up when posted yet are present in draft; first time for this happenstance in WP. This just in, from last night’s global GEM model run by The Canadians. Using a magnifying glass, you can see that these panels show a tropical storm (now only known as Tropical Depression 12-E) moving… Continue reading Canadian dreams
Water, water everywhere in the sky, but not much fell on the ground
Yesterday was a disappointment. Oodles of water up there above us, as represented by cloud bases somewhere around 15 Celsius (59 F) yesterday morning, early Cumulonimbus activity–one was up toward Oracle by 10:37 AM–Oracle got 1.06 inches yesterday, but while the skies darkened over Catalina several times, they didn’t “unload.” Maybe only once or twice… Continue reading Water, water everywhere in the sky, but not much fell on the ground
“Great Unexpectations” (0.38 inches fell when almost none was expected)
Of course, the title refers to Dickens’ little known sequel (and frankly, a lightly regarded one) to his popular, “Great Expectations”. Dickens fully expected that by rushing out another novel similar to “Expectations” that a financial success similar to the one that “Expectations” had garnered for him would be easily acheived. However, like most sequels,… Continue reading “Great Unexpectations” (0.38 inches fell when almost none was expected)
It was dust not smog
Let us compare different dusty sunsets, one from Saudi in 2007, and one from Israel, 1986, together at last for the first time: Standing by for rain on the horizon, Yours truly, CM
Smoke attack
It was hard to see all the smoke around yesterday morning after the two previous stunning days with high visibility. I was thinking I had never seen so much smoke in Catalina as I saw yesterday morning. Here is some photos of that awful event: In the afternoon, the smog was gone, mixed through… Continue reading Smoke attack
Before the rain: a LOT of clouds, some smoke
Got pretty upset later yesterday afternoon when I saw these scenes off to the south through west, creating a little “sky rage”: Its not CIrrus or Cirrostratus you see, my friend, though as a nascent cloud expert, a CMJ, you may well have told a neighbor at the time of these photos, “Look, here comes… Continue reading Before the rain: a LOT of clouds, some smoke
