GFS 0z keeps the heat all the way to the 19th this morning.  

I believe there has been some major hail storms in the past, one of these deposited over a foot of hail in Tunbridge Wells in August on 6th August 1956. I have a photo in the History of British weather showing what appeared to be a winter wonderland. The thunderstorms dropped over 40cm of hail in places which some people mistake for snow.

Looking at the charts for Sunday there is potential for some large but localised thunderstorms to breakout in southern and southwestern England. Low pressure (1011mb) humidity and more instability in the atmosphere than we’ve seen for a little while.

Yes, there have been several of those storms - the Kent Weather Book has some photos of them, including one in Tunbridge Wells in the early 80s. People mistook the hail for snow, but it was of course far too warm for snow!

Perhaps we might see some hail if the thunderstorms which have started to appear on some of the models materialise! GFS has fairly widespread storms in the middle of next week, as does whatever the BBC uses (used to be ECM, but I'm not sure now).

August shaping to be the best sunny month and easily exceed 200 of sunshine hours. Likely near 100 by now.  Far much better than July. 

WX Summary charts still uncertain about what's to happen in week2. Week 1 continues the present pattern of a hot continent, the heat spreading to cover England, and no significant rain except in the ultra-north plus a smaller amount around Belarus. Week 2 looks more interesting with cooler (but still warm) patches appearing in W Europe including a general cooling of the British Isles; the Baltic hangs on to some heat but N Russia much cooler. Rain now appearing in a new place for the third successive day, now affecting the British Isles with patches to the E all the way across Europe.

Jet streaks to N of Scotland for a few days then no action until about Sat 20th when a S-ly dipping loop rolls across the UK

FAX shows LP near Brittany Sat 13th developing to cover Britain Sun 1th; trough over the S and a secondary centre off SW Ireland

GFS Op shows the current ridge of HP lying E-W across Britain being disrupted by LP from the south, 1010mb SW approaches Sun 14th, then a tussle between these two until the Atlantic steps in, LP covering Britain Sat 20th and centred 995 mb NI. This slowly drifts N-wards as the ridge of HP re-establishes Thu 25th - but not strongly as LP from the Continent is still hanging around and something that looks like an ex-hurricane is in mid-Atlantic

GEFS mean temps dropping steadily to norm over next weekend with significant amounts of rain in many ens members starting up. Mean temp near norm and intermittent rain for the rest of the forecast period but plenty of variation. Some big rain totals in N later on

ECM similar to GFS though the LP at the weekend re-forms to the SW for a time before the Atlantic LP moves in, the latter more slowly than in the GFS model

Growing support for the heat to continue into next week in parts of the UK. Suggestions that thorms may be more of a risk in the west and north. Anecdotally, that seems to have been a trend in recent times with the south east often missing them or at least the worst of them.

Looks like an evolving situation still. T storms are possible for the south mid week onwards

How many 30c days can we get in a row. It looked like 7 or 8 , but this morning we could get 10 or 12. Does look quite stormy next week as well.

Agree. Keeping my fingers crossed that we'll miss them here.

Yes I have. You disprove it then? I can't prove what I've seen in August over 50 years ago,

It may have been a 5 minute wonder, I don't remember, but it did snow.

It's a freak weather moment/day etched in that you never forget.

I say 'etched in' as after, I was I always keeping an eye on the weather in the following Augusts, hoping it wouldn't be a trend.

I assume you must have been up a mountain, or have been lucky enough to experience something not in the records. There’s never been recorded snow in August in lowland England. 

i think 8 is the most likely, with Monday being the last one (for now!) GFS operational is pretty much at the high end. 

I’ve also noticed the GFS moderate the 850s somewhat. The mean had crept up to almost 20C but is now back down around 17C at its highest for London.  

All the same there is still a decent chance of 4 35C days in a row, maybe even 5 (unlikely, but would match 1976). That would mean 6 or 7 in one year, which I don’t think has ever happened before?

Well if that is snow, then it also snows all over the tropics.  Everywhere. 

To be fair, that would still be anecdotal, let alone be statistically impossible.  Just saying.

   I thought everybody loved a good thunder storm??
