Been working on a talk for Feb 23, 1990…..at the U of WA, so not blogging too much. Will likely post “back to the future” talk in a few days. Its a science story, really, not quite a “talk.”
But enough of my blabbing, as Rob Reiner might say, lets move along to some INTERESTING spaghetti.
First of all, things rolling along pretty much as foretold in spaghetti at our last meeting, a week or so ago. Storms are rolling in on schedule now. Had 0.50 inches in the first one, here in Sutherland Heights.
Below, is the five day from now spaghetti or Lorenz plot. You may recall, though I doubt it, that spaghetti was foretelling a big ridge that would break off into the Arctic and help shunt storms into Cal and the West Coast.
Well, that was spot on because it is going to happen after a little break from the current storms. Of those, the rainiest one for us is tomorrow and the next day. Likely to see an inch or more here in Sutherland Heights from that one storm! Looks like a quarter of an inch will be the total for the current one.
All this is so great for the spring bloom, too, that time of year we all love.
But enough of my blabbing #2, as Rob Reiner might say again, lets move along to some INTERESTING spaghetti.
The weather pattern way ahead
But the real news I wanted to inform you about through excessive speculation is the spaghetti plots for about two weeks out, shown below. This ios amazing in my view.
I wonder if my one reader can detect the amazing part?
Its the grouping of the blue and red lines in the eastern Pacific that seems extraoardinary in a plot like this where “chaos” usually rules in this sector THAT far away in time.
Here, the grouping of red and blue, a coming together which can never happen in the political color realm, means there is a very strong signal in the measurements. The slight errors input at the beginning of the model runs leads to close to the same forecast even 15 days out!
So, what does it all mean?
This is no doubt in CMP’s mind that this strength in a medium range forecast is due to the constraining of weather patterns by the Big Niño now in progress. That feature is keeping the jet stream constrained to bash the West Coast and Cal, and that’s what you get out of this plot above. Very strong storms are now setting up to bash the West Coast, ones associated constrained to do so by the powerful El Niño.
The current storms, as you likely know from media weather folk, are classic in their El Niño appearance, streaming into Cal and AZ at lower latitudes out of the Pacific. So far this winter, in Cal and AZ, we haven’t seen much effects of a Big Niño until now.
That 15 day spaghetti plot is not one that we here can pin confidence on about a lot precip, but hang on in Cal, especially beginning about a week from now when this pattern really sets up and then crescendoes.
Below, just decided to add the 10 day spaghetti, kind of out of control due to excitement. The bunching of red and blue contours is astounding to me in this one, that in the east Pac resembling that of the geographically-forced bunching we see all the time in the extreme western Pacific off China. This bunching, with a dip to the south (trough) off the West Coast indicates a very reliable forecast of a huge trough bashing the West Coast about then (Friday, 5 PM AST, Jan 15th). Maybe, just MAYBE, those Cal reservoirs WILL be filled up in a single winter!
