Quoting the comments I hoped I would not be able to see, but can still  see because others engage:

"If you see what the BBC longer range is now hinting at, you won't be expecting anything more summery. They have specifically referenced 2012 and patterns being similar.

They seem to be erring towards a write off summer, with perhaps a 35% chance of a few hot spells. Not looking good for 2021 at all."

This is not true and nothiing  of the sort has been said!  In fact, the summer outlook is for above average.

It is the same every time things look bad. I am also a sufferer of depression and I know this game:  Involve everybody else in your misery for your own needs. And it is working.  I am getting too depressed to come on this thread.

Please! DO Not Engage in this!  It is nothing to do with weather or models.  Please do not enourage it! Silence is the best medicine.

Any decent weather keeps getting put back in the model runs now for some time. Central Europe has the best of the weather at the moment with temperatures in the mid 20's and looking to continue there. Back in Glos'shire its quite bleak with unsettled conditions and cool temperatures, rainfall for this month edging 60mm. Hopefully this current pattern will break allowing something more settled.

Just removed a number of OT comments. 

16-dayer shows NW Europe remaining cool for both weeks, joined by NE Europe n week 2 where it has been rather warm recently. Rain mostly over S Britain week 1 moving away to give a band over continental Europe week 2

GFS shows LP generally over the UK for the next week with new centres drifting in from the Atlantic across central Britain esp Mon 17th and Thu 20th, the latter generating a N-ly as it moves on to the E. This is briefly displaced by a toppling ridge of HP Wed 26th (with a bit of warmth) before new LP over Biscay appears and moves  N to Ireland Sat 29th

EDIT FAX shows more localised troughs along the Channel until Mon 17th followed by a N-ly controlled by LP further N over Scotland Mon 17th

GEFS mean temp stays resolutely close to or a little below average, and with showery rain throughout (but op & control both dip some 7 or 8C below to match the N-ly mentioned above, ca Sat 23rd, followed by a bounce back for the op above norm on the 28th). In Scotland more runs also show the dip around the 23rd, but less of the showery rain towards the end.

ECM similar to GFS though the LPs mentioned are deeper

If the 0Z verifies the snow potential thread will be back.

Wouldn't rule out low ground snowfall (in Scotland) in June at this point!

The synoptic charts are giving me cause for concern. For weeks now there has been a persistent  high pressure over Newfoundland and another high pressure over Greenland. Occasionally they thrust a ridge in our direction which gives us the presistently low temperatures.

Hardly any mention is made of this. I've noticed this on the synoptic charts on Look East for ages now.

Yes that's right at this time of year even with temperatures s little below average it will feel warm in the sun, but that doesn't make the conditions 'average' as some people have suggested, it will very likely be a much cooler and wetter than average month.

Isn't part of the reason the south-east is historically more densely populated because the weather is warmer and drier?

After all, people retire to Bournemouth and Brighton not Braemar and Baltasound :-)

Not my understanding; cold, dry air is the worst, but yes to sunshine as research has now indicated rapid reduction in viral viability in even moderate UV.

One of the reasons the Lancashire cotton industy developed where it did was that the damp climate meant the cotton threads were less likely to break during manufacture.

It would probably never have taken off in Essex!

Some straws tonight as both GEM and GFS build the Azores high very nicely over the UK by day 9/10.

Yup, but I've seen this all before this month. Some very tasty looking charts, sometimes even consistent over a few days but always at 10+ days out, near enough to be of interest but always too far away for any degree of confidence. Then they disappear completely and return again at 10 days. Rinse & repeat. This is liike the winter search for cold, forever chasing the end of the rainbow, always just out of reach....

Indeed,  we need the high pressure to get in the 6 day range to have a chance.  The GFS run really is a beauty though. 

Something has to budge soon. Yesterday’s GEFS were so linear, clustered and flat for so long you knew something had to give.

I think by the last week of May we’ll have very different weather to now. Whether that’s cataclysmic flooding, a return of unseasonably late frosts and snow flurries, or a suddenly record breaking heatwave I don’t know.

There is at one member of this evening’s GEFS set that promises to smash the May max temp record. P15. Modelled max of 30C on the ensemble line chart means a mid 30s actual max. At least 33C. There is another member (P20) that gives almost the whole country several days of frost, with some widespread hill snow. Various runs promise different locations a month’s worth of rain in a day.

ECM also brings in the Azores high by day 9/10

Something need to give sooner than later as it been nearly 2 months now since we had a normal Spring warm spell.  Now is down to 5 weeks left to the longest day and we lost so much of useable long daylight hours so far.

Strange amount of variability across the set for temperature tomorrow I don’t think I’ve seen that amount of variation so soon in time before.

TWO grid points may be slightly different, but the first 30C of the season is safely in the bag tonight.

Yes, you start feeling like you are wishing your life away at the moment. Waiting for the cold to arrive, waiting for the cold to go, waiting for the rain to come, waiting for the summer of course and all this while you are looking forward to the end of the lockdown. I'm too old to be wishing my life away!
