Measurable rain to fall on beautiful Catalina in February 2018!

At least 0.02 inches, as deduced from this keyboard–haha.  Should be more than that, but, in a rain of drought,  everything seems to work against getting a major rain.  Raindrops will  possibly begin as early as  12:02 AM on February 15th, though probably not.  Maybe a day or two later if a tropical insertion of… Continue reading Measurable rain to fall on beautiful Catalina in February 2018!

Our last hope for rain in early Feb; a thin blue line (a 552 decameter one)

Blue, as in the 5520 meter height contour line as produced by a single run of the many NOAA GFS model re-runs with those little “perturbations” of the starting data.    Below, our only hope for rain here in Catalina is if the model run with a 552 decameter height contour over eastern Pacific across… Continue reading Our last hope for rain in early Feb; a thin blue line (a 552 decameter one)

Hot ‘n’ dry model outputs for Arizona reverse course overnight!

Check this out.  Unbelievable, really, though it is kind of what our ensembles have been telling us would happen.  These outputs of jet stream location shown below are but 6 h apart, and that’s what makes this comparison so remarkable; they are so drastically different (check how the orange colors have moved around, and then… Continue reading Hot ‘n’ dry model outputs for Arizona reverse course overnight!

Another day with Altocumulus clouds, and what else? The usual: aircraft-produced ice canals

They seem to go together every time we have Altocumulus clouds; aircraft flying through them create holes or canals!  Have been photographing this phenomenon since the early 1980s, and I have not seen it so consistently occur every time there was a flake of Altocumulus around as has been the case here this winter!  Its… Continue reading Another day with Altocumulus clouds, and what else?

“Delta model”? Will someone have cold spaghetti on their face?

Yesterday, after I finally saw the model run based on global data from 5 AM AST  for Feb 6th, CMP (the writer) was gloating that bit.  The troughy, cold spaghetti for AZ, that which had been excitedly written about yesterday,  was being confirmed; the interpretation right on, it seemed.  Why even look at more model… Continue reading “Delta model”?

Sutherland Heights logs 0.22 inches yesterday; Jan now at 1.32 inches; average is 1.60 inches, water year at 1.71 inches

0.22 inches was, indeed. how much rain fell in the form of drops  from Nimbostratus clouds yesterday as a modest little rain band generated by a rapidly moving trough swept through during the afternoon.  Regional precip values can be found here.  Our local area got the most, up to about a quarter of an inch,… Continue reading Sutherland Heights logs 0.22 inches yesterday; Jan now at 1.32 inches; average is 1.60 inches, water year at 1.71 inches
