A toppler plume is often the result, 10 days hence, with

Scandinavia getting the heat. The warmth is still there on the gfs,
but the ECM shows just that; a toppler.

What's a toppler plume?

Shows on the 10 days charts, then ends up missing us to the East, The model predicts the plume, but not it's eventual path. No certainties that will happen, or even, yet, that the plume will happen, but that would be a "toppler".

I doubt whether you'll find that in published literature. *))

The possible plume is shown further east on the 00z gfs and ECM. It ain't coming our way, folks.

Not on the EC00 at T+240 it's not - 850hPa temperatures are as high as 20C as far as the East Midlands, with CAPE as much as 3,500 J/kg in eastern England at T+222. Not that this will necessarily come to fruition. In fact that specific scenario is low probability at the moment.

"Toppler plume" is a meaningless phrase. The plume, should it develop, may well be just east of the UK, as is so often the case, but that's nothing to do with "toppling".

Stephen.

I hope it achieves outcome.

"Shower" refers to something completely different to the actual processes occurring within the cloud, but it an accepted way of expressing what is seen to happen.

As with my phrase. I like it, you don't. That's not going to worry me. *))

PS Plumes really don't "develop to the east of us". You don't like the phrase "toppler plume" which describes the sequence of changes often seen on weather models in summer pretty well, but yet you keep saying this.

I think you'll find that warm plumes _do_ preferentially develop to
the east of the UK - due to topography, distribution of warm air over
Europe and the orientation of the airflow of the troposphere due to
that heat distribution.

=========

Half the battle in forecasting is clear communication. "Toppler plume" is used by nobody else on the planet and thus will not immediately be understood. Ergo it is a meaningless phrase. Moreover, it describes what you are trying to represent rather badly: cf the better use of "toppling high" (although not a favourite of mine), for example, during the winter, from which I presume you adapted your phrase.

I did not say that plumes "develop to the east of us" once, never mind "keep saying it".

Had a re-think about the 00UTC EC yet?

Stephen.

I suppose so. Semantics again. The development of a plume can be thought of as taking place along it's journey. I had used the idea of "develop" as "To bring into being". You are correct, most pass to our East and therefore continue to develop to our east, however, we are talking here about models changing their forecast of the path of the plume from its first appearance. Hence "toppler".

It's
