Mike - a note about the election - I'm still trying to force my mind to work on it (G).  It is a struggle.


I am enjoying your wx posts again.  First - I am not trained at all in this, so what I write is just observations and guesses.

I've watched the earth wind map for quite some time now.

https://earth.nullschool.net/#current/wind/isobaric/1000hPa/orthographic

The controls when you click on "earth" in the bottom left corner are fascinating.  My impression, after studying this for some time, is that we seem to have entered a period where the systems lack the "order" they previously had - often highs and lows alternating with the jet stream setting up waves around the northern hemisphere in an orderly fashion.  It seems to me - and i'm interested in your comments - that what is lacking currently is that order and the tendency for that orderly pattern to move west to east.  That movement normally makes for the alternating wet/dry cycle in ag areas like the corn belt.  From what i know about chaotic systems, this is not unexpected - I've seen it in markets a lot.  Do the conditions we see now suggest to you that this must have been what were seen in the 30s?

On a very different subject - are we seeing something like this in our country - or, more correctly, in the western countries?

For a very long time after studying markets for decades now, I have said that everything is born with the seeds of its own destruction.  Are we seeing this unfolding right in front of our eyes in not only weather, but in other areas too?  Speculation, I know, but could the chaotic behavior of the weather combine with that of the politics to make for some extremely difficult times ahead?

This started out as a wx comment - now I wonder if it belongs more in the NTR section .  .  .

cfdr,

I think that almost all the extreme, unusual, unprecedented and historical weather that we've had recently is just the same extreme, unusual, NOT so unprecedented, historical weather that has always defined our weather patterns.

The biggest reason for it to be otherwise is............perception.

That was a wonderful map that you showed me. What did it look like 20 years ago?

Nobody knows because it didn't exist then. I can tell you from watching the weather almost all day long for much of the last 39 years, that it wouldn't look much different.

The average person that knows nothing about weather(you know quite a bit, so I don't mean you) can get 100 times more weather stuff  on the internet than I could as a professional meterologist, with a satellite dish on my roof getting all the weather back 25 years ago. 

And we have the media. OMG. Everything is reported just minutes after it happens but they exaggerate so much of it.

I watch ABC Nightly News on many nights(the tv station that I was chief meteorologist at for 11 years 1982-1993).

They often lead with weather that is not all that extreme and frequently have a story on the current weather, going to their meteorologist, when it's just a bunch of strong thunderstorms and not an outbreak, or a bunch of 2 inch rains, or a few inches of snow that they will claim "is threatening 63 million Americans".

The exact same weather before the fake climate crisis would NEVER justify making one of their top stories.

It appears to be much worse because that exact type of weather was happening since humans have been measuring it but never got reported out the wazoo like it has since the fake climate crisis has brought it out. 

As a weather nut, I love seeing stories about the weather but the way they describe it makes me cringe.  

SENSATIONALIZATION SELLS!

I may have started my career 39 years ago, but I have access to all the weather records going back to...........when we started recording the weather. I refer back to them for various extreme or similar events or to look for analogs/similarities hundreds of times every year.

Those reporting and exaggerating extreme weather in todays world just do not do this.

Would this make an eye catching headline "Today's heavy rain event has happened X times before in the last 150 years"

Is this one better:

"Heaviest rain in the last century!"   (for that location). or even "Heaviest this century" And maybe the same type of  rain event has happened a dozen times in the last 25 years but in other places in the US or  even 100+ times in the world.........but the headlines use "unprecedented" and "historic" in a way to mislead you to think that it's NEVER happened before........just because it didn't happen before just like that in that one location.

And our accurate weather records don't go back that far anyway. Something may not have happened before in the last 130 years but it likely happened several times before in the last 1,300 years and maybe numerous times the last 13,000 years.

People think that the weather over the past 130 years of measured weather is supposed to define the extreme range of weather that ever happened. 

The weather is NOT more extreme and in fact, because the temperatures have warmed the most in the coldest places during the coldest times of year, the weather is notably LESS extreme in some realms. Definately less extreme cold and less violent tornadoes but MORE extreme heavy rains(the atmosphere can hold 7% more rain) and a slight uptick in heat.

He still plays skillful chess and we can do it via a video screen, where I see him and his board at his assisted living facility and tell him what moves to make for me on his chess board.

His house didn't even have a telephone growing up in the inner city of Detroit(until his  sister, 6 years older than him got one in high school).

He never  met his dad.........but became a gifted industrial engineer for Ford Motor Company for 39 years after serving in WW2, then graduating from the University of Detroit.

Then he vowed to be the best Dad the world has ever known to his 6 children because he never had one.

He accomplished that too and is still showing us how to live life, not just as our Dad but the oldest person that most of us have ever known personally!

The models are having huge shifts in HDD's from run to run because of the handling of a big upper level low in Southeast Canada associated with a strongly negative --NAO.

Ensemble Mean NAO Outlook


In addition, a strongly positive +PNA

This encourages air masses in the West and in Southern Canada to move from north to south into the US. How much cold there will be from the source region(that could be fairly mild) and how amplified the pattern will be has been changing drastically each run.

Looks like the Euro is going to come in around -7 HDD's too. 

It finished and the 12z run was actually -8 HDD's vs the previous 0z run!

The changes never represented a pattern change to colder but, instead just how much cold was going to surge south in week 2 with a temporary break in the mild pattern............that will resume right after it.

For the first time this month, the week 2 pattern is evolving more strongly in a way that  suggests a potential pattern change that is capable of unloading more serious cold in sustained fashion.

The AO is really plunging to solidly negative at the end of the period. The NAO stays negative!

This is the 500mb anomaly below at the end of the period from the GFS ensemble mean. The center of the positive height anomaly in Northern Canada is the foundation for the potential new pattern turning colder. If it grows and heights drop in the US..........viola.......we will have an efficient north to south air mass delivery mechanism!

No precip for the Southern Plains the next 2 weeks with soil moisture deficits increasing and less favorable for the HRW crop in that location that needs good moisture for  robust development (to better withstand Winter kill threats) before going dormant ahead of Winter.
