Powerful hurricane to not enter Arizona even though the model shows this happening; horse story

Many of you probably were gasping for air after having seen the WRF-GFS model outputs from last evening’s 5 PM AST global data.

A large hurricane, really more the size of its typhoonic big brothers in the western north Pacific, and one that also dwarfs the late tropical remnant, “Newton” ,  that came through here a week or so ago, is shown to move along the SAME path as Newton into Arizona in about 13 days from now.

For those few of you who did NOT peruse the 00 GMT, CUT,  Z output, here are the fantastic fantasy hurricane depictions that this model, with all of its calculating power, shows entering AZ on the 26th.  Kind of fun to see even if it is bogus because it indicates that such a strong tropical cyclone could come through here one day.

Below, from IPS MeteoStar, these, maybe the best fake AZ hurricane depictions I have ever seen.  Note all the isobars, i.e., lines of equal pressure with this tropical cyclone in AZ, and then remember for all its rain, little Newton had virtually no signature on pressure maps! Hell, the pressure didn’t even fall at Nogales as Newt approached.  Pitiful.

But it wouldn’t be like that in this fantasy hurricane.  Tremendous pressure falls would occur as it entered AZ giving your microbarograph quite a workout as the pressure plummeted and then went up as the center passed by.

You do have a microbarograph don’t you?  If you don’t, think about it.

Next,  you’re curious, though,  about what steering pattern caused this hurricane, previously shown to stay far offshore and dissipate over some jellyfish and plastic particles way out in the Pacific in the models.

Let’s look, again from IPS MeteoStar at the steering situation at 500 millybars, or in around 20,000 feet or so:

Here the configuration. You're breathing a sigh of relief, maybe even chuckling: "That's not gonna happen." Ludicroous really, though withing the slightest realm of possibility, maybe one in a thousand. Like kicking a field goal that goes through the uprights after bouncing off an opposing player's helmut. I mean, it could happen, like a golf shot at Carmel that bounces off a stunted cypress and goes into the hole from 500 yards out, or.... OK, enough of that.

What you need to have any confidence is a big trough along or just offshore as we had with Newt, not a slight little itty bitty eddy aloft that has to be in exactly the right location at EXACTLY the right time.  I mean, its like a ball that goes for a home run after it bounces of the  center fielder’s head1

Hold your cash on the sand bags.

Finally, there’s really nothing from the spaghetti factory that supports this.  Boohoo.  What you need in spaghetti is strong support for a trough along the coast, not the below:

Yesterday’s clouds

Spectacular Altocumulus castellanus and floccus (no virga) passed overhead during the morning.  I hope you documented them with a few photos.

9:11 AM, on the trail looking at a superb example of Altocumulus floccus. Estimated height, 12,000 feet above ground level. No ice visible, so tops likely warmer than -10 C.

No ice visible, so tops likely warmer than -10 C.  The bases of these clouds evaporated almost as soon as they formed, but the tops not so much, rose steadily after bottom disappeared.  Tallest ones were likely more than 1,000-2000 feet tall.
12:16 PM. By this time, which was good, smallish Cumulonimbus clouds recurred over the Catalina Mountains mostly east of Ms. Lemmon. Nice stages of ice development in the tops from newly risen, no sign of ice, to frizzy all ice remains, over and over again.

Horse story

Have to depart from clouds and weather to tell this tale.  Yesterday I stopped here to let the mighty Zeus rest a little.  I let him graze “off leash” on some of the still-green nettle grass in a gravel parking area next to our cottage.  I then went to get a pail of water for him, the pail being on the north side of our house.  When he saw I was leaving,  he immediately followed me like a dog.  It was kind of cute.

But as we got to the gravel outside the north porch of our house, our two dogs, Banjo and Emma were going nuts at the sight of a horse outside the north windows.

Zeus got distracted by all of the commotion in the house and went onto the porch to look in one of the windows to see what was up, or maybe he saw his own reflection and thought it was another horse?  Here is the hilarious scene:

2:21 PM yesterday. Zeus looks in to see why the dogs are barking so much.

1This actually happened in South Dakota,  at Mitchell’s Cadwell Park,  during a  baseball game I played in ’72.  I was catching in those days for Mitchell Commercial Bank.    Our center fielder,  a track star, ran to get a scorching line drive to medium depth center, and racing to his left,  reaching up to grab it, the ball instead bounced off his noggin and went some 40 or 50 feet over the fence!  He was OK.   We had no “concussion protocol” in those days.  Had a chance to bat against the legendary Canova, SD,  pitcher, Lee Goldammer in that game.  Whiffed on three pitches;  was maybe at bat for 30 seconds.
