Last year was a good summer down in England up until some point during July when everything then went downhill even down there.

I think down south August wasn't very good, with less sunshine than average. 

I'd say summer 2017 was okay but that's it. June was the best month relative to average.

The reason for that though, wasn't really because we were going on any sort of extended dry spells. What actually happened was that we kept on getting the same frequency of official rain days (a rain day being defined as one where we get 1 mm or more of rain), but the amounts of rain which we were getting on those days was now much smaller.

This meant that it was wetter than average during that month both in terms of the actual rainfall amounts, and in terms of the number of official rain days and since that was true during the rest of the summer months as well in this part of the world, that made for a rather poor summer overall.

Nevertheless, that relatively dry second half of August did mark the beginning of a drying trend overall, which then led us into a dry autumn (albeit with a slightly wetter than average September) followed by a drier than average winter where January was then, the only wetter than average month.

GEFS not remarkable but they don't tell the whole story.  I'm starting to wonder whether we're heading for a historic spell of fine weather.

I think the rest of May can pretty much be ruled out for any significant rainfall, apart from the odd thundery low trying to push into southern areas.

We could indeed be beginning a very dry spell of weather, and I welcome it especially moving into summer! It's even more when you consider that so many notable weather events this decade have been because of copious rainfall rather than a lack of it, so it would be a nice change.

Is the May NAO still factored into the Met Office winter forecast ?

An easterly at this time of year wouldn't be very good for this part of the world either or anywhere down the east coast of both Scotland and England for that matter. If the air from the near continent is dry enough, we would probably still get some sunny afternoons once any low cloud and east coast haar had burned off, due to that strong sunshine at this time of year (by the time in question, we will then just be less than a month away from the summer solstice).

However, I would imagine that it could get a bit depressing after a while seeing every morning start off with that easterly muck in the form of low cloud and/or haar, resulting in yet more grey skies  and another permacast hell. Furthermore, that cool wind from straight in off the North Sea would mean that it would never actually get all that warm here, even if the Sun does break through in the afternoon.

We had plenty of that easterly stuff at the very end of the winter and during the first half of this spring, so we could probably do without getting even more of that as we head towards the start of the actual summer. If we do though, I'm sure that we will be hearing plenty more from Richard from Aberdeen on this subject.

Now I'm not so sure. The horrible overcast isn't clearing today and could stick about for the first half of the week, then the risk of an easterly setting in. Not impressed in the slightest. Getting 3/4 grey Sundays in what is supposed to be the sunniest month of the year would be appalling

The model output generally speaking continues to look pretty good for virtually all of the UK in the short to medium term.

GFS this afternoon is showing a run of very high minimum temperatures for the south, end May-beginning June. Chance of a May min record being broken?

It makes sense. Parts of the South coast already have a big range between wet winter and dry summer (eg Lyndhurst ranges from nearly 100mm in Dec to 35ish in July, unlike say Essex which is dry year round). A couple of degrees extra warmth even with little or no reduction in summer rain would give enough soil moisture deficit for xerophytic plants to thrive.
