A bit of everything from the 6z. Not sure about the low pressure it's placing us under by next weekend though! It seems to be followed by a Ntly, then a rebuild in pressure with ever increasing temps beyond that!

At least there's a chance of a substantial pressure-increase over Europe and the UK, around month's end...would tie in with some of the other longer-term forecasts?:oldgood:

Word of warning gang, there is some absolute filth indicated for late June on the GEFS 6z in terms of unseasonably cool and unsettled but in amongst the dross there are some very summery members too, anyway, that's just my unbiased agenda free opinion!??

It has no support anyway..just trying to lessen the pain rather than adding to it!!?

Looking at the Gfs 6z operational there certainly is thunderstorm potential from late tuesday and continuing through wednesday across the south, southeast and east anglia.

Please don't say that! We're all on one weeble cheek here.

Anyone looking at the models and getting frustrated at rain bearing charts should weep more tears in the respect that last year, the fallow year, would have been a dust bowl!

Just for fun, a comparison with the clusters this morning for T300 with those on exactly the same day last year.

The difference between NW trough in 2018 and NE trough in 2019 is just about there, but at this stage the 2018 chart doesn't scream a huge improvement on this year's charts. Perhaps too early to write off the whole of June yet - there's definitely a route to a much better final week ?

The triple point of the frontal system will track north east during this evening and overnight and the main rain bands will be in the area of the occlusion and the cold front.  Thus a band of showery rain remaining in the vicinity of north Wales and England whilst some quite intense downpours track north initially through N. Ireland/ the north of England and then Scotland  Drier further south

ICON 12z has some heat pumped up at T180, wouldn't take much adjustment to get a proper plume here:

as it is it's a glancing blow, but spare a thought for Siberia, ICON T165, those huge four-figure numbers falling from the sky are going to hurt if one catches you!

There's a real worry about more flooding in the already flood hit areas on tues / wed as heavy showers and embedded thunderstorms move north and also develop in-situ across the s / se / east anglia / lincolnshire due to the increased humidity according to the 6z operational and likely the 12z too.

UKMO T144, compared to ICON at same time UKMO first:

UKMO looking much better and as always it is frustrating that this model stops at T144.  On to the GEM and GFS...

OK so three charts to add to that now, the GEM, GFS (FV3) and the old GFS all at T144:

image.thumb.jpg.6cfd5d18e5c3d3b8c0b8a2acafb3aee1.jpgimage.thumb.jpg.e078ab1a401c4aff8bcbd1f05fc5fb27.jpg

The message is one of improving fortunes.  It is interesting that the old GFS has not been totally put out to pasture...maybe NOAA have some concerns still re FV3, I am wary of it.  FV3 has consistently outperformed the old GFS on NH verification stats, not by much, but it has.  However, it has shown a cold bias in the US, and has shown some odd solutions for the UK too.  

So it's good we've access to both until September it seems.

And now it seems the GFS 12z not making as much of an issue with low pressure has the 6z did... For me that's an improvement.

not sure about that. next monday 12 degrees? to me this worse than 6Z

Completely different on the other GFS. It's unsettled but very much warmer... Look at the uppers.

Come on, uppers are pretty irrelevant if stuck under heavy rain, might make difference of 3/4c. 12c and raining, 15c and raining - who cares...

still hopefully fair enough away to end up being completely different than the currently output.....

GFS looking good for a push from the Azores at T192:

Power to build. Compared to its predecessor, which puts us back in the cement mixer!

So by T192, uncertainty reigns, still a lot of model watching before the eventual destination a week of so from now can be predicted with any confidence...
