Immediately, “BS” is for “Big Storm” ahead, not something untoward.
OK, first a piece about yesterday’s unusual clouds at Cirrus levels; you wouldn’t want to be flying in, or underneath these:
You can also these specks fly by in the U of AZ time lapse film. If you look at the film when they do, you can see them twisting around. Cirrus at that level (CM estimated 25,000 to 30,000 feet above the ground) are normally like sculptures; frozen in time as they pass by this time lapse camera with little or no internal movement.
You could also detect internal movement from the ground in real time in these specks (as we can with Cumulus clouds all the time, since we’re so close to real Cumulus fractus) so it must have really been churning up there.
This patch of specks only took a few minutes to pass by, so you were lucky if you say them.
Of course, you’re only interested in the Big Storm just ahead, not turbulence….probably have grown impatient by now, not wanting to read about itty bitty specks in the sky that might have been associated with strong turbulence. Well, its still “in the bag”, no need to worry. See below this map from our Canadian friends’ model. I really like this map, so no need to look farther. Also, I wrote some things on it for you:
That “kicker” trough just off the Cal coast is going to kick that trough “ball” just off Baja at us as in a field goal in American football, and we are the goal posts.
When a trough is booted out like this one will be out of its nest, the upward motion in front of it is in enhanced, so that the clouds and precip intensify, become more widespread. Its going to head right for us, as it accelerates toward the NE.
This means, in turn, that the very strong rain band already in place in western Arizona, will intensify as it moves east across the State. This is pretty darn exciting because from here it would mean quite the downpour, hours of rain, and almost certainly thunderstorms on March 2nd. However, flooding is likely as rainrates will likely get up to an inch an hour or even more as the band passes over us.
Still sticking with 0.9 inches as “best guess” here in Catalina, top amount, 1.50 inches, if band lingers longer. Secretly hope I’m low….
In one last forecast panel, this MONSTER approaching the Cal coast. Its pretty far out there, as I am being today with the notes on band favorite, Oingo Boingo and sociobiology below, to be reliable, but its shown up a couple of times now in our model runs. It is unbelievable in strength to be forecast as far south as off central Baja, and I wanted to show you what an amazingly strong storm for so low in latitude would look like, if nothing else:
PS: A powerful jet stream is near us now, so more strange clouds, lenticular-sliver clouds, and fine granulations in Cirrocumulus and such, are likely to be seen over the next couple of days. Have camera ready.
PPS: Still some flow in the Sutherland Wash as of yesterday.
1The genius of Danny Elfman, that is, composer of the Simpson’s theme song, and the only composer to be nominated for two film scores in the same year, and also the leader of Oingo Boingo, an LA punk rock/ new wave band in the early 1980s, formerly known as , “The Mystic Nights of the Oingo Boingo”, more like a Spike Jones gag band. An early influence on Elfman was the concept of sociobiology, as represented in “Only a Lad“, a song about an inherently bad “lad”, satirizing some popular, widely held concepts on the causes of mischievous behavior in that song. A sample below, if you care2.
“The lady down the block,
She had a radio that Johnny wanted oh so bad,
So he took it the first chance he had.
Then he shot her in the leg,
And this is what she said
“Only a lad. You really can’t blame him.”
“Only a lad. Society made him.”
“Only a lad. He’s our responsibility.”
Oh, oh, oohh oh oh oh
“Only a lad. He really couldn’t help it.”
“Only a lad. He didn’t want to do it.”
“Only a lad. He’s underprivileged and abused.”
Perhaps a little bit confused?”
2Being a rad-lib in those days, I thought it was INCREDIBLE to hear such a song with THOSE lyrics in the early 1980s on the University of Washington student radio station, KCMU-FM, again, if you care.
