‘Manda rain

BTT you read this, rain oughta be falling or near by as the remnants of  ‘Manda hurricane dribble into Arizona today.  Looks like there’s just enough rain upstream right now (4 AM) to produce, hold your breath, a MEASURABLE amount here in Catalina!  Likely will be just a few hundredths, though, as much as two tenths is about the top potential from this.  At this point, anything measurable is a fabulous rain!

Mods have been oscillating on whether it would rain here for many days, but last night’s run ended pleasantly with a “correct” forecast of measurable rain.  See green pixelation over Catalina below:

Valid for 11 AM AST today. Heart of rainband over us then, mod says.

Your Catalina cloud day

(Also, another great cloud movie from the U of AZ here....)

5:15 AM.  Cirrus
5:15 AM. Cirrus, leaning toward “spissatus”, heavy dense patchy Cirrus.
7:42 AM. Cirrus fibratus/uncinus. “Cirrus” will do it.


4:35 PM. What would a day be like without Altostratus? Here, “translucidus” because the sun’s position is visible. When the sun can’t be seen, its “opacus”, like a lot of science can be.


5:27 PM. Walkin’ doggie and this seemed like a nice shot of the rustic neighborhood streets, the Catalinas, and up top, some glaciating Altocumulus, castellanus on the right side; hasn’t gone through the ice forming stage yet, or the ice hasn’t fallen out that’s in it.


7:18 PM, Crepuscular rays show up as the sun sets due to smoke and haze under the clouds. The clouds? A mix of flakes of Altocumulus and Altostratus (the solid blob), some Cirrus on top of it all.

 The weather way ahead…

Not a lot showing up here for mid-June, so won't say anything about that.
Valid for June 12, 5 PM AST.  Not a lot showing up here for mid-June weather, so won’t say anything about that.  I suspect it will be warm, though.
