Moist tongue failing

That’s pretty much it for the weather just ahead.  Nice upper low passes overhead in the next coupla days, but it really needed an steroid-like injection of tropical air from way down south to do much for us in the way of measurable rain.  Oh, sure, we’ll still get some clouds and isolated showers, maybe one or two with lightning somewhere in the whole state of Arizona, but our chances of measurable rain here in Catalinaland have gone way down because the moist tongue hasn’t materialized in time to reach us, but rather will be shunted to the east.  But, the skies will be spectacular, even if they’re dry for us.

For a psychological lift, in addition to the one provided by large amounts of coffee,  generous rains  will fall in drought-stricken NM and west Texas as our little disappointing low approaches and moves over us.  OUR tropical air will be just a little too far east, but great for them.

BTW, the Canadian model, the one that had so much rain in our area as late as 36 h ago, has bailed on rain here, as well in the past two model runs.  Probably won’t be going to Canada now for any vacations in the near future; pretty bitter about those misleading forecasts.  I think they smoke too much up there, too.

Yesterday’s clouds

First, in case you’re mad at me for predicting measurable rain, 0.05 to 0.25 inches, have some kind of “rain rage” going on now, a picture of a cute dog to help you get back in control of yourself:

10:04 AM.  Flying saucers!  Altocumulus lenticularis clouds sometimes trigger calls to the police department that a flying saucer is about.   Had a real scare back in the 50s around Mt. Rainier, Washington due to an Ac len (true story).

12:12 PM.  This one looks painful.  Never seen anything like it before.
12:12 PM. This one looks painful. Never seen anything like it before, a kind of yoga for clouds, “downward dog” cloud formation.

 

12:12 PM.  Wouldn't want to be flying under this one; suggests extreme turbulence to me.

12:44 PM.  That shredded. ragged base below the lenticular in the center also indicates heavy turbulence.  The smooth cap is due to a temperature inversion that allows some give, a dome, a hump in it, but nothing more.

1:46 PM.  An example of almost invisible Cirrus/Cirrostratus.  Kind of a hot research topic, "invisible CIrrus", ice crystals floating around up there that are too low in number to be seen, but can be captured in aircraft instrumentation.  This is about as close to invisible Cirrus as you can get.  Look hard and you will see the faintest whitish haze above the flecks of Ac len clouds, one has a trail of fine ice coming out of it.  Ac len remain stationary while the air flows through them, so the ice ejects on the downwind side.  No sign of an Ac len having produced the whitish haze above those cloudlets, though.  Personally I have never seen invisible Cirrus.
1:46 PM. An example of almost invisible Cirrus/Cirrostratus. “Invisible Cirrus”, btw, is kind of a hot research topic since clouds affect the radiation budget of the earth.  That kind of cloud is just ice crystals floating around up there that are too low, and small, in concentrations to be seen, but can be captured by aircraft instrumentation., which is how it was discovered.   This is about as close to “invisible Cirrus” as you can get. Look hard and you will see the faintest whitish hazes around and above the flecks of Ac len clouds; the one a left center has a trail of fine ice crystals coming out of it.    Ac len remain stationary while the air flows through them, so the ice ejects on the downwind side. But, no sign of an Ac len having produced the whitish haze above and to the left of that  cloudlet, though.   Personally I have never seen invisible Cirrus.

 

The weather way ahead

NOAA spaghetti plots suggesting that tropical air ahead of a trough may yet bring us rains in early June.  Check it out. 

Other than that, our only chance for measurable rain is in the next 48 h when MAYBE a rogue shower might hit.  But, no matter what, pretty skies anyway for the next couple of days.  Have camera ready.

The End.
