Thanks Phil. Big storm presently North of the Loire and heading about
020 fairly quickly and, if it gets that far, looking as if it might
just clip, or just miss Kent coast in a few hours time.......now
that's deja vu from last week!
http://www.isleofwightweather.co.uk/live_storm_data.htm
There's also a line of storms heading towards London, which has
developed very quickly. Could be some atmospheric fun and games in the
SE this evening.
http://www.metoffice.gov.uk/weather/uk/radar/index.html
Some very heavy rain further North too. Quite an evening for UK
weather......except for the South Devon coast where we have grey skies
and drizzle. 8-((

Actually, there's a lot of developments ahead of that Loire storm and
it is all happening very quickly. The whole thing has much more of a
Northerly track to it now and at the moment, it has Kent and possibly
East Sussex in its sights. Well worth watching over the next couple of
hours. It certainly looks as if the cap has come off and there is some
extremely unstable air heading for the far SE corner.

Worthing/Shoreham area are developing rapidly, frequent lightning now over
the channel and from a storm which appears to be to the west of Worthing.
So much for my early night i have a 4.30am start in the morning!

Have you seen the developments just leaving the French coast?? Torro
have a tornado warning out for the SE and this has the potential to
develop into a very big affair. That's a supercell storm heading for
the far SE and it could cause problems. Met office haven't picked up
on it on the warnings site. Wake someone up!

, the local radio just 10 minutes ago said that any remaining 'light'
showers would quickly die away to leave a dry night, someone look out the
bloody window!!!!!
Keep your head down!

More developments off the Eastern coast of Kent. It's not that often I
get excited about a weather event in the UK, but this is one. The
worst might miss you Robbie, sorry to disappoint, but if this
continues to develop, there could be the biggest storm in ages over
anywhere in the SE corner. Fascinating viewing on the lightning
detector. STILL no warnings on the Met Office site for the SE corner.
There'll be hell to pay tomorrow, if there is damage. Surely someone
must be on duty in Exeter and seeing this!

Hmm, well my last words to the nightshift went something along the lines of
the risk of thunder (in the SE) in the next few hours is about PROB10 or
less...
I'll get my coat as Richard Dixon would say.

quick check of the TAFs for here and no thunderstorm warnings, rain eased
here now but more lightining over the channel from what appears to be
clusters of small but quite active cells, this coupled with the lightning to
the north is the most impressive i've seen here for ages, fantastic cloud
formations ;-)
As you say it looks like the monsters over the French coast could hit
Kent...................

I just called the Met Office to ask about the lack of warnings. The
fellow on the phone could not have been more blaze if he'd tried
(maybe he did!). Oh well. They don't seem that bothered about it and
are "keeping an eye on it". Must be me then.
Well, boys and girls, there's one possible supercell 30 miles from the
South Coast and there's another development already producing
torrential rain and lightning over North Kent. There's not even an
"advisory" on the site, even though Torro has this warning out:
"THREATS
Tornadoes, hail to 3-4cm diameter, wind gusts to 60mph, CG lightning,
torrential rain.
SYNOPSIS
Moisture plume is destabilising with the approach of upper trough.
Cloud layer shear sufficient for organised multicell storms and
possible mesocyclones. Whilst much of the activity should be
marginally elevated above the boundary layer there are suggestions of
sufficient low-level instability for storms to become surface based,
especially before midnight. Should this occur, a tornado or two is
possible, although wind/hail should be the main threats."
We've had advisories for situations where under 10mm of rain has
fallen over a 6 hour period recently! I don't get this. Are they
gambling that tehre won't be problems???

The storms are essentially mid-level (see the 2000Z METARs) and as such
there's no guarantee the criteria for flash warnings will be met as the
precipitation is falling into a relatively dry boundary layer.
http://www.metoffice.gov.uk/weather/uk/guide/key_warnings.html
Either way I can assure you developments are being closely monitored by the
duty staff, as they are every hour of every day, and warnings will be issued
as required.

That's the last time I read one of your TAFs...

There has been thunder here more or less continuously since
8.45 pm and it is still rumbling on to the south. Some spectacular
lightning around 9 to 9.10 pm, but none of closer than about 2 miles.
Still getting the occasional flash and there are very few periods of
silence. (9.50 pm now) Someone, around Westerham or Oxted, is having
rather a good storm. Only a brief splash of rain here so, ahem, coat
not needed.

Looks like we may be in for an interesting night in South central
France, too - the second one in a row, with storms developing to the
west and southwest. Meteo France has issued a Vigilance
meteorologique for storms in much of the country, although at the
moment it doesn't look that spectacular...

You're in Denver, or San Salvador, or somewhere round that way, and
you're worried about a storm in the English Channel?

There's something MCS like developing over the south-eastern side of
Biscay/far SW of France which various models then carried NE over central
France overnight so probably a good call.

Vicarious R us, Alan!
I'm hoping the MetO have got this spot on - and they may well have.
Superb lightning displays are being described, but it's providing
little danger and no torrential rain/hail/tornados. The storms appear
to be staying as mid-level storms. Well done the forecasters if this
is still the case when I wake up.

Went for a thunderstorm chase to the south-east at 10 pm.
Spectacular lightning (all c-c) all the way and occasional very minor
flooding (Westerham, Limpsfield) but no really heavy rain or gusts.
Some mistiness at the very top of the North Downs (870 ft). It was
very difficult to determine where the centre of the storm was - it was
everywhere except to the west. All very characteristic of a medium-
level storm and it is difficult to see how the boundary layer could be
engaged as the temperature was 17°C throughout, making TORRO's warning
of possible tornadoes look rather hopeful, if that's quite the word.
Dawlish
Just a very interesting night. Weather warnings were issued, just
after this woosie went to bed. Reports of torrential rain, some hail
and localised flooding, reading around the weather sites and the best
lightning show for ages. No tornados reported.

I wouldn't want your job, if you have to get up /that/ early. That would
mean me getting up 'alf hour afore I went t'bed.

Who's Torro? Not sure I can see the purpose of your phonecall, if it
were adding some useful information or a ground report to the
situation then I could and it would be appreciated, but to ask why no
warnings were out? I'd interpret that as you suggesting that no one
was watching the situation or paying attention (which would never be
the case) or that issuing warnings is simply a case of looking at some
radar or sferic data and hitting the 'go' button? Wish it were that
simple.

I wish it were that simple as well. If I lived in the areas hit by
torrential rain last night, I'd have appreciated more warning than
they got too.
