Half-baked

With a high in Sutherland Heights/Catalina yesterday of 107 F, maybe fully baked is more appropriate, though “half-baked” does align itself pretty well with this blog. It was so hot in TUS yesterday, the venerable U of AZ sounding plot, constructed on a “Skew-T” diagram, was not able to capture the surface temperature at the time of the balloon launch in Tucson. Don’t see that too often. Looks like the horizontal scale (abscissa) needs to be extended to 50 or 60 C (113 to 131 F). Hahaha, sort of.  See below:

The moist air surge predicted by the models yesterday, the one rushing up the Gulf of Cal, is happening, though maybe at a walk or trot instead of the “gallup” foretold by the models. So, if you get up and notice that the dewpoint is over 50 now, that why; you’re experiencing the rush of humidity from tropical sources.

And with the half-baked air by afternoon, why it makes sense to anticipate a full-growed (as we westerners would say) Cumulonimbus cloud in the vicinity today, yay. BTW, if would be even that bit hotter without all the haze due to dust, and maybe some smoke, since the sun was dimmed that bit glaring down at us through that stuff.

 

Your clouds from yesterday, such as they were:

1:40 PM. As humilis as humilis can get.  Prescott was having a thunderstorm at this time, and you can’t even see its top, that’s how bad the visibility was.  (Of course, in LA, or Bakersfield, yesterday would have been a stupendously clear day!)

7:00 PM. The clouds filled in a little toward sunset, and some anvil Cirrus from Cumulonimbus clouds in the western part of the State, blocked the sun as it set.

The End.
