How cold were those Cc clouds? See below. (Begin technical module) In the mid- -20s C, around -15 F. Height, about 21,000 feet… Continue reading About ice-in-clouds and APIPs (or high temperature contrails)

Rain to fall in Catalina! (as shown in this latest model run shown below)
Finally found some rain for you. Took awhile. Came from the 11 PM AST global data from last night using the WRF-GFS model, our best. The rain falls around the 19th, “only” 11 days from now and during the “sweet spot” for southern California rain in mid-November, 10-20th, which gives it a few more percent… Continue reading Rain to fall in Catalina!

While waiting for S, the (NASA) Diary of the Great O
While waiting for the remnants of former H. Simon to pass over us during the next couple of days, bringing some rain, starting overnight, got distracted while looking to see how many rainfall measuring stations they have in Baja Cal, and found this about the Great O from NASA. Its a pretty fascinating read I… Continue reading While waiting for S, the (NASA) Diary of the Great O
Interesting optics yesterday; substantial rains just ahead
Pretty boring lately…. No motivation here, even after caffeinating royally every morning. Have had some pro work to work on, too, like reviewing a manuscript for a journal–loosely translated, work that’s largely comprised of “finding fault in the work of others,” which I am pretty good at, to be a little immodest. Due this weekend,… Continue reading Interesting optics yesterday; substantial rains just ahead
Some recent clouds that have floated over Catalina, AZ
Many of you are starved to see some low clouds rather than a few Cirrus or Altocumulus clouds under a blazing sun, about 27 million degrees F in the core, only 10,000 F at the surface we call the “photosphere”, what we see up there. (And you think its hot in Arizona!) So, I thought… Continue reading Some recent clouds that have floated over Catalina, AZ
A day with Cirrocumulus, Cirrus and Cumulus; summer rain season looks to start on time
What a day, Mr. and Mrs. Catalina, except for that last second “header”: The weather way ahead, 10 days and beyond; dreaming green pixels Rain showing up around these parts beginning overnight on July 3rd-4th, kind of a normal time for a summer rain season onset. This from last evening’s global model crunch. Prior… Continue reading A day with Cirrocumulus, Cirrus and Cumulus; summer rain season looks to start on time
Another hurricane (“Cristina”) forms off Mexico; can AZ rain be far behind?
Looks pretty good…. Two completely different computer models show tropical moisture getting into Arizona in about 5-6 days a resulting preview of the summer rain season. You can find quite a bit of “green pixies” (areas of rain denoted by areas of green pixels) in Arizona here from IPS Meteostar’s rendition of our best model,… Continue reading Another hurricane (“Cristina”) forms off Mexico; can AZ rain be far behind?
Nice weather we’re having; snowbirds ejected to the north too soon
Sure, there was a little mischievous wind in the early afternoon, BUT, as a day in late May in Catalina/Sutherland Heights zone of Arizona, wherein the temperature is less than 100 F, well, it was pretty darn great. Another one is on tap today just like yesterday today, too. Feeling sad about the early, northerly… Continue reading Nice weather we’re having; snowbirds ejected to the north too soon
Late morning cold slam
Its not a breakfast at a restaurant chain, but a sharp cold front passage later this morning, say between 10 AM and Noon. Should be pretty interesting. Temperature will drop about 10 F in an hour. Expecting/hoping, too, for a little measurable rain with this “FROPA” (frontal passage in weatherspeak). The brisk winds, as… Continue reading Late morning cold slam
Sprinkles in area overnight!
Some sprinkles/radar echoes passed overhead early this morning. Will check, as you will, for drop images in dust on solid outdoor surfaces to possibly report a trace due to drops that reached the ground. Going out now with flashlight, to heck with that coyote over there. Result: looks like there were a few isolated, larger… Continue reading Sprinkles in area overnight!
