ICON 18z has flipped to more unsettled next week. Let’s see if the GFS holds out as it was showing the most settled outcome for most of next week.

Regardless of what the models show, I think (or hope) that high pressure will dominate again from the west and will bring temperatures above average after this 3-4 day period of unsettled and cooler weather. Even a lot of long range forecasts, if not some, are going for a very dry second half of June with high temperatures and blue skies so hopefully it does materialise and give us exactly that!

Speaking of blue skies, I saw this in the blue sky this afternoon (not the best location to view it I know!):

But you can just make it out.

Spring has been exceptional this year. Fingers crossed for a more exceptional June and July with more heat and thunderstorms! ⛈️☀️

Take care all - stay safe.

Hello guys and good evening

I think the models are all over the place from 120,will this trough drop down from the north over the UK?will it get shunted further east?,i hope so 

latest from cpc shows the hp cell drifting slightly more to our east in the extended but we need these dragging heels to get unhindered from the crack in the pavement as we are still the wrong side of the high with winds still from a relatively cool source

610day_03.thumb.gif.f6abf8039b7dcde00ee4bd52b88cc4c0.gif814day_03.thumb.gif.65e9f412d425dcc424c6c76aa8cf776a.gif

hopefully in a few days that things will change for the better to warmer weather again

it has been a good couple of months weather wise and with this lock-down it has been a very good excuse for some good model talk in here and i feel like one of the big family members and i am glad to take part in here

i started back at work last Tuesday and it was very strange after so long and i felt the sense of discipline towards other work members and visa versa 

we are slowly getting there but we have had a big hit in terms of this virus and i was very scared at one point and there was fear in us all

please still keep safe and don't be complacent,the killer is still out there

sorry for the slight off track but it has been an emotional roller coaster 

on to the 18z,now lets see if we can get this Azures high further west/northwest

C U in a bit.

Can we get a cut off low in Iberia?,that would send warmer or even hotter temps up from the south.

We have a good strong hp cell in our vicinity from 192>,the strongest on the entire globe,i just hope that it places it's self favorable that we can benefit from it...

As expected, the GFS pub run is starting to build HP and some warmth after the cold plunge. Perfect!

@James1979 It was quite the sight! My mum took a better photo than me before it dissipated but for some reason I can't seem to edit it into the post.

ICON brings down a swathe of -4 uppers across a large part of the UK

image.thumb.png.bbf219fcbceb4b71d296f1c6e6af095e.png

Seems to follow the ECM of yesterday somewhat in its latter stages

UKMO at 144...

that's some trough

image.thumb.png.3beef32f08bb0b756e9b92148b754619.png

GFS at 144 is slightly more benign but more precarious looking than the 18z

Although it looks like gradually becoming cooler and more changeable / unsettled beyond the next few days, the longer term signal from the GEFS 0z is for a return to more summery conditions..certainly an increasing chance anyway!..so..June starts great and perhaps towards mid month and beyond we will see more high pressure and possibly even some plume / continental potential!

00z runs are pretty dreadful to be fair.

ECM is  like a dog with a bone with this unwelcome northerly...

Don't want to see troughing becoming 'stuck' in our locale.

Exactly just bought a bigger pool aswell. Hopefully we see the models showing something more akin to the 18z gfs by the time we get to this evening. The 00z ECM looks far away from anything like we've been getting for a fair while.

Probably the worst set of runs/outlook we’ve had for a couple of months. How long will it last?

Good morning folks.:hi:

Once again the GFS 00Z op has us all under cooler air, come Friday:

But, after that, uncertainty rules the roost::unsure2:

h500slp.png    h850t850eu.png

h500slp.png    h850t850eu.png

h500slp.png    h850t850eu.png

But, anywho, judging by some of the above comments, I must be seeing a custom GFS!

And, by the looks of things, a customised set of GEFS ensembles too!:oldgrin:

t850Bedfordshire.png    prmslBedfordshire.png

So, to sum up: one day below 15C and the chance of seeing some rain...I've seen worse!:oldlaugh:

Yes still very little rain on offer apart from the end of the ECM. What is it with the ECM these days? It always used to be the GFS overblowing the lows in FI

GFS and GEM not too bad.

ICON and ECM awful.

UKMO not great, but we don’t know where it will go next.

But still a high chance that the northerly will be further east. Maybe the overnight runs have overdone it?

No change in any of the 3 500 mb anomaly charts I use for predicting the major upper air pattern in the northern hemisphere. All 3 keep the pattern as shown on the last post I did, just putting the last evening one in from Noaa to show the major ridge-trough pattern. The 8-14 Noaa also looks pretty similar so it might even extend 2 weeks from when it is due to develop, say Wedenesday as the colder air moves south. The Met O Fax for T+120 looks a good description and scrolling down for a further 2 days you can see the pattern for the surface and upper air.
