Thanks for that summer sun... Not all bad then, let's hope it has more success than it did in winter though..

Indeed, just a bit of patience required from the impatient grasshoppers!!..we are not eating into summer yet and as I've said, most of this week looks good for the majority, and you're right, reading miserable comments does have a deflating effect but we just need to look for the positives.!

Just interested in the uncertainty that is prevalent at the moment, here is the situation at T180 on ICON, GEM, GFS and FV3:

I don't think this evolution is nailed down at all,  yes higher pressure towards the south, but other than that the models aren't telling us much.

This evening's gfs 5-10 anomaly The NH profile no big surprise as the pattern has more or less been covered in previous posts

Following this week's fine and warm weather (apart from the far north!) there looks like being a more unsettled blip, at least for the north but then from around day 10 there's a signal for a return of fine and warmer weather thanks to the azores high according to the GEFS 12z mean..and indeed the 6z mean before it!!..it's really not as bad as some on here are painting it!!

Defo some stonkers starting to creep into the 12Z ensembles:

But quite a lot of scatter too, though!

Looking at the Ecm 12z so far there's plenty of fine and warm weather to come for the rest of this week with the exception of northern scotland..a change on sunday but look at the 850's!!!

Karl beat me to it but he's just about right.... As usual... Plenty of settled Conditions especially S/SW areas, things going downhill into the new week with cooler temps and a fair bit of rain in places, especially Northern parts, folk up North are probably sick of hearing this by now.... Sorry chaps...

A quick look at the holiday weekend with the ecm

Saturday sees a wave forming on the front with rain staring to effect N. Ireland and western Scotland that will progress east to effect the north of the country through the rest of the day. Dry elsewhere with sunny intervals and apart from the north temps a tad above average.

By midday Sunday the wave has developed and is 999mb west of the Hebrides and the cold front is tracking south east down the country. So quite a wet day with showers behind the front and quite windy.Temps trending below average behind the front.

The wave is well clear by Monday but leaves a legacy of showers with further rain from another front effecting the north through the afternoon. Temps are now below average.

No words necessary!!..actually there are, according to the Ecm 12z following this week's warm settled weather, next week looks cooler and unsettled, especially further north!

Out to day 10 with ECM and still a bit meh. But I think if it ran a few more frames we would see high pressure building in from the SW.. that's the hope anyway.

We be sugar coating it Karl.... The Azores high is coming home soon... Could be a second class delivery service though and not the 1st class recorded delivery service some may want.

And the ecm 5-10 anomaly Certainly some differences from the gfs, particularly upstream, albeit the upper trough is firmly adjacent to the UK

Just comparing the day 10 Ecm 12z op / mean...the mean wins because the azores high / ridge looks better placed / aligned!!

But GFS 12Z ensembles isn't looking very nice though particularly Scotland where its wet, cold and miserable for about a week post the 27th of May. Better in the SE, warmer and dryer.

My post is about the Ecm, not the Gfs, incidentally the GEFS 12z mean looks increasingly settled and warmer the further ahead it goes into the start of summer...I'm looking for the positives!!
