Quite a few of the longer range models are chap. Perhaps you should try looking?


JMA not great, UKMO average at best, BCC average at best.


But best you look for yourself instead.

At a glance, long range models look average which is to say the usual variations will be apparent as we head through the summer. It is why any long-range text summary will hedge its bets with most summer weather types occurring at one stage or another.


To concur with just about every other poster in this thread, there is no evidence to write off the summer. Certainly not based on one stubborn trough that may dampen the south for the next week.


I am glad you're going to bring in some subjectivity though - it is not like the rest of us are predicting a BBQ summer

GEFS 00z is looking less promising for the south than some of the recent updates. 



 


It's a different picture as you head north.

Brian's GEFS post above covers the outlook neatly though IMO any changes for the south since yesterday are only marginal. 


GFS keeps HP around for the coming week but that patch of cold & wet LP embedded in it sticks around S England/N France until Fri 2nd and even then HP is to the W so winds still in the NE for much of UK. fter that the ridge topples slowly and a W-ly pattern sets in by Thu 8th  (last frame Sun 11th shows an autumnal LP near SW Iceland, not at that stage affecting UK exc far NW)


ECM also shows that patch in place but replaces it after Fri 2nd by a large LP mid Atlantic wit S/SW winds, cool in the NW but could be quite warm in the SE Mon 5th


 


EDIT - I misread Brian's post so  have tweaked this one

GEM, GFS and ECM all have high pressure building in nicely in about 7 days. 


Until then decent for the north of England unsettled further south. Difficult forecast though as some days look ok some days quite poor. Bit of a nowcast situation. 


Some people get annoyed with Moomin because he writes off Summer all the time at the slightest hint of unsettled conditions .  But I dont think hes being entirely serious most of the time.

The N/S divide of this late June is unusual and fascinating. The outlook is, regardless of objections, pretty poor for the Southern half of the country. It is pretty good if not excellent for the Northern half, more specifically the North West.


To take this morning's GFS, average Tmax based on grid points for the next 7 days: 17.8C (London) vs 20.8C (Manchester), and 19.6C (Glasgow). That's including today's miserable cold one in the North West. Excluding today Manchester's figure is a whopping 22.2C.


Rainfall wise we have 47mm in London by next Thursday, 7mm in Manchester and 2mm in Glasgow. And there is a maximum grid point for the country of 59mm sitting roughly over South Oxfordshire e.g. Witney. 


This is worthy of note because it's quite a persistent pattern, and every run that goes by seems to prolong the influence of the trough to the South and high pressure to the North. More of an April/May pattern than a late June one. Hence I think very interesting to see the different reactions to the same model output from people based in the North and South. It's as big a divide as the popularity of Boris Johnson in Chesham & Amersham vs Hartlepool - both populations looking at the same data but coming to completely different conclusions.

Yes it is statistically wetter here in terms of rain days than most major towns and cities in the UK (NOT Glasgow) which is much wetter, but Cardiff for example gets more rain in terms of the amount of water. But the city’s wet reputation is overstated all the time and it gets right on my nerves. I always bite back as well which must make me seem a bit odd and anal about it.

The last 9 day's have for sure seen some wet weather in what was an otherwise very dry month up until that point, but even in those last 9 day's there have been some nice sunny warm dry days. Unsettled weather in June (especially back end) is completely normal and to be expected most years - so predictable they built a roof a Wimbledon because of it!!

This weekend actually looks pretty good for 95% of the country maybe some rain for the south coast Sunday.

What day would seem wetter, 5mm from constant light rain/drizzle or 5mm from a short thunderstorm in an otherwise sunny day?

Good point Col. The last week or so has been more notable for the lack of sunshine (Wednesday was the only sunny day here) in late June than the amount of rain. If we'd had 60mm of rain spread over a few torrential thunderstorms and then the sun had reappeared for a few hours on each day, most people on the forum would be loving it. 



Back to the models, there is an increasing risk that the whole of my week in south Devon, starting this Saturday, will be affected by rain. Some models are showing it drying out from Wednesday others are showing it lasting until Friday. Longer term there are increasing signs of a return to a more typical pattern of high pressure to the south west of the UK.  North and west is best next week. If you've decided to have a holiday in the Scottish highlands and islands, next week is looking glorious.

Longer term outlook looks pretty good to me from about middle of next week most days look like being around 25c with high pressure, certainly better than last Summer.

Manchester 15th rainfall volume, 9th for rainy days.


Liverpool a few places drier.


Leeds is wetter than both (which I find surprising)

I know we're venturing way off topic but the rainfall stats are interesting, particularly that Manchester is drier than Leeds!


I think in a country as small as Britain relief is probably the biggest determinant of rainfall. Take my field for example. It's in Kent, which contains some of the driest sites in Britain close to the sea particularly the Thames Estuary. It is in the far South East. But being inland(ish) and in a N-S valley up in the downs at about 80m asl it actually gets a lot of rain, despite also getting lots of sunshine and warm average temperatures. I've measured 569mm in the year to date and considering the second half of the year is on average wetter, that probably means ending up somewhere between 1,200 and 1,500mm for the year. More what you might associate with the Welsh hills. There are 2 stations within 5 miles of me one of which gets almost exactly 50% of my rainfall (on the Eastern side of the ridge and I am on the West), the other about 75% (on the Northern edge). Some of that may be rain gauge calibration in the other sites but I know mine is pretty accurate as I've calibrated it with a physical collector.    


By the way this evening's ICON is a nice one. The rain ends mid week and tops out at 28mm in Wessex and 25mm around London (2mm in Manc, zero in Glasgow).

Before LeedsLad comes on and whips us all into shape, I can pretty confidently say Manchester is wetter than Leeds (certainly in terms of rain days, not sure about actual rainfall).


Leeds’s figures are misrepresented from the Bingley weather station which is 200m up in the Pennines - for Leeds itself you’d be better off using Church Fenton which is much much drier. 


Manchester (Woodford) is also wetter than Liverpool (Crosby) but not by much.

For the same reason the east coast can get days/weeks on end of easterlies and northerlies at roughly the same time.
