About real clouds, weather, cloud seeding and science autobio life stories by WMO consolation prize-winning meteorologist, Art Rangno
Yesterday’s drama, forecasting for picnics, etc.
In case you missed it, and you probably did because you were still in bed while I was doing things for you, there was a pretty sunrise to start the day yesterday, one that would not disappoint later by being a dry one. After all, we’re here in the peak of our summer rain season.
Got 0.27 inches here, and 0.40 inches in Sutherland Heights. (The U of AZ rainfall network will have lots of data, some places getting over an inch yesterday. Pima County amounts here.)
BTW, as mind wanders, the real monsoon in India is a a little below normal this year so far. But, check out these forecast maps from IPS Meteostar and look at the west coast of India. It rains every day all day for the 15 days of the computer model run. Nothing really too unusual about that, rain every day all day on the western Ghats, 10-20 inches a week. Now THAT is a monsoon! Thought you might like a little distraction, get you out of any ruts you might be, get you thinking “outside the box” for a change.
OUR story, the long and winding one, continues below, though it can be seen in totality, in the short form in the U of A time lapse movie. This is a great U of A movie, with several “dump trucks” going by. Its amazing how much water can just suddenly be unloaded by a cloud!
Also, lenticular clouds (hover clouds) can be seen at the beginning and end of the movie downstream of the Cat Mountains, unusual for summer.
The weather ahead.
U of A mod results not yet available at this hour (5:08 AM), but other model outputs suggest another three days, including today, of the kinds of scenes shown above.
Every day will be that bit different in shower coverage, of course, that governed by subtleties in the flow aloft, grade of moisture supply, dewpoints, etc.
But those days ahead will be great enough, our deserts being drenched here and there, the desert foilage exploding. Enjoy those clouds while they’re here.
The End.
