Thanks Ray, this solves the problem. I asked this, not just for me, but I share the link for the weather freaks on the other side of the Atlantic Fortunately Ray does understand.

By double clicking at the date (which is at 12th of august) I get the latest of your thoughts of 24th of August. And now it fits. So there is a problem with the website. Which I wanted to make clear. Being not native English-speaker, it was more difficult than I thought to do. Edit. After trying again, it remains wrong. Another way to get the right article, is to go to 'Blog archive' on the right side. Than you get the latest!

Preliminary Analysis of the Polar Landscape for Boreal Winter 2023-2024 https://easternmassweather.blogspot.com/2023/08/preliminary-analysis-of-extratropical.html?m=1 Perhaps, now people do understand. First you see Polar landscape, the second is extratropical which contains much more than polar. So the description of the link and what you get is not the same.

The link says preliminary analysis of extra tropical, I get don't get this but instead polar vortex analysis. So, the title says A, but I get to see B.

What I mean is this. Please the read the link.

Thanks a lot, seems to me, there is something wrong, because when I click on the link, the website shows your article of 12th of august about the polar vortex.
