August disappoints: a look back at a disappointing August, and then a look forward at haze

August rainfall total in Sutherland Heights:  A measly 1.10 inches, to editorialize that bit, rather than to just report facts.   Average August rain here is  3.16 inches.  Egad.

End of looking back….”What’s the Use” (Tuxedomoon) said it best, well, maybe.

What about the haze?  Where’s it coming from and its awful! And its here again today.   Reminds one who lived in southern California of summer skies in southern California, hazy, whitish, the orange- colored sunsets that people sometimes thought were “so pretty” but they were ugly because they were orange because of smoke and smog and s like that.

Where’s it coming from, to repeat?  Not sure.  But see back trajectories below.

These suggest its coming from the east in the last day or so of the trajectories.  The trajectories start high up because we’re in the descending air branch of an upper air anti-cyclone that’s dessicating the air, preventing even little baby Cumulus from forming.


Lidia’s moisture will help some, but it appears no rain will reach us today,   Dang.

But things get more promising for at least a short return of the summer rain season (remember, the real monsoon is in India) in the immediate days ahead,  phrasingly vague enough to insure a great forecast verfication! haha

6:44 PM. Sunset over the Tortolita Mountains, where else would it be from Catalina (at this time of year)?
6:44 PM. Orangey sunset over the Tortolita Mountains, where else would it be from Catalina (at this time of year)?  The orange suggests a smoke aspect in the aerosol.
