I accidentally mistyped “Digging” and that’s what came out, Diggomg.” I can’t pronounce it either. Then I thought, you know, that it could be quite a hook for a blog, a word no one’s seen before, and would want to know more about it. Maybe more than the two general readers I get would want to look into what “Diggomg” is. So, I have left it intact as an cheap blog attraction strategy.
Besides, things happen for a reason, even if its just a mistyped word due to sloppy fingering…
Here’s the “dig”:
“Digging”1 is a common phenomenon in weather and jet streams, that’s usually the way storms get all the way down to Arizona because storms and jet streams plunge southward or to the southeast from the Pacific and that process we call, “digging.”
But here, an extraordinarily narrow current filled with little disturbances (kinks in the winds aloft) goes all the way from Spokane to Socorro Island in the tropics off Mexico, and that makes this map so unusual. You won’t see this everyday. You might want to archive it.
Here’s the next panel, 24 h later, and, as the current going to the south ends, it does so with a very strong current passing over southern Cal.
What’s the portent for Catalina weather?
Hahaha—Just kidding. Ending right there would be cruel. It would be like TEEVEE people do, as in, “Will it be cold tomorrow? Stay tuned for a few hours and we’ll tell you!” We don’t do that here. Read on…..
Low pressure centers form in response to all this current plunging south off Baja, and those centers that form are WAY down off southern Mexico where its so unusual to have that happen in the wintertime. Down there, they get loaded with water and then begin moving north, almost like tropical storms, though having far weaker circulations.
That, my fellow weather friends, is the excitement ahead: plunging jet, surface low pressure centers forming deep in the Tropics, ones that then move north and are likely to affect the Southwest with generous rains. Its not in the bag, though, since lows like that are not well handled by the models, seem to have a mind of their own. So, in the end, the models are pretty clueless about where these juicy systems will end up.
HOWEVER, if you do rummage through the IPS MeteoStar progs, and I strongly recommend that, you’ll see that the rains begin affecting us possibly as early as the 27th. All in all, an unusual situation is unfolding in front of us over the next few days, more clouds and rains to dream about helping to spike our wildflower bloom that bit more.
BTW, that mod run from last night also had quite the Cal rain blaster beginning on the 30th, likely leading to flooding. Presently, none of that rain gets far enough south to affect us.
The Real End
1Many of you probably won’t remember the little known, but nevertheless classic Bob Marley take on digging:
Who can forget those classic words, “Archaeologists are no wacko scientists.” (“Wacko” in the reggae dialect is pronounced like “waco”, as in Waco, TX.)
