    My personal opinion would be that it counts as a Plume, BUT only just. The actual LP isn't coming from Spain; it's more from the Atlantic. However it does look like it's sucking up a plume, albeit a small one, of unstable mid-level air sourced from the Spanish plateau. 

    Of course I'd much prefer the chart Mapantz showed for July '19, and there's zero arguement whether that one counted as a plume!

    This is a beauty, the cell NE of Leek, quite active at the moment, unfortunately too far to hear anything.

    My tuppence worth is I do consider it a plume but far from traditional. If you run the CAPE chart from this evening through to tomorrow night on Meteociel, you can see how the instability wafts north from the Spanish plateau/Pyrenees region. Although as Mapantz is getting at its far from classic and the air mass is moderated somewhat on its route north.

    This is how half of our plumes occur - a low in the Atlantic helping hot air waft up the eastern side, often from the SE.

    One could think of this one as a sort of ‘returning plume’.

    Then again it could be an upside down plume like the one from Scandinavia in May 2004... that was just bizarre.

    Literally constant thunder

    Looks brilliant. Very much alike to storms and conditions I have seen over Majorca, Spain, and parts of Greece/Turkey, I.E a well defined sheet of biblical rain in a confined area.

    A couple of faint rumbles to the South East. Near miss.

    Was watching this cell develop pretty much over my house where it moved eastwards, been hearing constant low rumblings of thunder the last 15 mins!

    That's our chances gone for the day. Everything was building perfectly but it's all heading South, blue skies now at the back, great cumulus clouds though, precipitation showing on radar but not quite there to go pop

    Did the cell over the Peak Disrtict just die off? That was short lived, but intense, with me seeing it only from a distance.

    Unfortunately not every Spanish Plume is a 'typical' Spanish Plume (like the one you have highlighted). The variation of the "Modified Spanish Plume" as I referred to before (with credits to Sue Gray & Lewis) looks a bit more like this:

    482484776_modifiedspanishplume.thumb.png.9d5ca6ac79d90baa30d10fcdf042cce9.pngsp.thumb.gif.5725b8453ee4baaad07580a6f6ffdf31.gif

    As quoted by Suzanne Gray & Lewis "Unlike the classical Spanish plume the upper-level trough has stretched and thinned equator-ward and is forward (northwest–southeast) tilted. This can lead to a cut-off upper-level feature which is typically centred to the northwest of the Bay of Biscay." Taken from their paper (Categorisation of synoptic environments associated with mesoscale convective systems over the UK). However, we can agree to disagree of course, but yeah I do admit its not your classic spanish plume🙂

    There's no way you can compare that FAX to the image of the modified plume. The jet axis isn't heading towards the UK, from the South. It's skirting around the South and in to the low countries. If we're calling that a plume, then we've already had multiple plume events this Summer, but I don't remember them?!

    Nevermind, the cell developed more over Blythe Bridge and Caverswall area. Seems like Stoke-on-Trent is setting off some storms for the east of it!

    This is nuts, I'm sitting RIGHT on the periphery of this storm, still basking in sunshine with the angle of the sun, while I look south and East the sky is black as night, and I hear consistent constant rumblings!!

    Obviously the FAX and the modified plume image aren't going to be identical. I mean the jet axis in this situation imo sort of "ingests" the low from the south across Iberia. I mean it's quite an awkward non-clean cut setup anyway but I can understand where you're coming from🙂
