How long will the fine weather continue for? GFS 00z says there's no end in sight, at least for southern regions. 

Also looks like the GEFS has shifted towards a warmer / hotter and drier longer term outlook. Fire and brimstone stuff for some I suspect.

If that the case many records will be broken in term of sunshine hours, max average, dry duration days and parching giving off very strong smell now at nights which I experience normally in Cyprus at nights.    Complete contrast to last year models so confident showing never ending unsettled runs.

Indeed Brian I worked out the average day T for London until the 22 July =25.7c we can add a couple on which I have not done.

Also of note some members going very hot again in the 3 week fab stuff.

An increasing number of very hot ensemble members (>15C 850) at the end of the 0Z GFS run. My pessimism from a couple of days ago is starting to evaporate.

I know it has been less spectacular in the SE... but come on! :D 

You remind me of me. Constantly looking at the output when we should be just enjoying what’s right in front of our noses.

And I’m not particularly bothered (so long as my long planned mass barbecue on the 20th stays dry), just interested in the output.

But whilst it is looking less hot later in the period, its still mostly dry for southern England as far as the eye can see

Last night was horrific, couldn't sleep at all. Hopefully will improve a bit next week

a few days ago GFS was confident of a breakdown, now the block renews itself

Horrendous stuff for people like me.

Future weather buffs will look back at the data for 2018 and think, wow, a proper Siberian easterly, with heavy snow falling in -5C daytime temperatures in late Feb/early March, then another blast of snow in mid-March, followed by a heatwave reaching 29C in April, and a very dry and sunny June and (at least) first half of July. We have been spoilt this year!

EPS has both pressure, and heat, building over the eastern Europe region during the last 3rd of the month. Any blip betwixt now and then looks to be shamefully lame.

Worth a read (it's quite brief). Emphasizes that persistent easterlies are the key to great weather in the British Isles, whatever the season:

Just turned from the football to GFS 12z. At 96hrs there’s a tiny little football of an ex hurricane catching the jet stream in the western Atlantic. I wonder what impact it’ll have.

Oh dear. The rest of the run has it drifting into the vicinity of the UK, filling all the time and sending the weather downhill. Thankfully it's all out in FI so not to be taken seriously.

I have seen these ex hurricanes derail settled spells before though. Anyone remember Bertha? It sent the rest of August 2014 down the pan.

Gfs members look hotter at the surface out until the 15th Wednesday cooler day is more or less dropped
