Catalina summer rain climo (again)

Running out of material, which is quite interesting because I haven’t been doing much, so am reprising these….

cropped summer 2012 rainfall

We had a little uptick in rainfall last year mostly due to that four and half inches in July.  Very nice.  No trend is evident in the summer rainfall here, global warming aside.

When it falls in summer….

Hmmm. Just noticed a discrepancy in the years of record. Huh. Must investigate later.

 

Some of yesterday’s clouds

One of my specialties is cloud bottoms, and there were several opportunities to photograph them. Here’s a quite nice one, hoping one day it might appear in a gallery, it’s that good I think. It was just starting to unload its watery burden onto the unsuspecting folks in south Catalina and Oro Valley (see next shot):

Models chock full of moist days for at least a week ahead, so “let the games begin”. Certainly we Catalinans will get nailed one of those days. Extreme SE AZ has been pretty wet so far, with Douglas having almost 2.5 inches already. Will be green down there soon! Might be worth a trip to see how things are coming along.

 

 

 

 

 

 

 

 

 

 

 

The End, except for this shot of the prior day’s really dramatic sunset:
