He was the only one who made regular use of the term and it was only back to 2012. Was he bumped off or what?

5 May 2012 = 5/5/12 = eel?
What the hell does that mean?

Pity he never kept a blog.
Well at least it will be on the FAQs won't it?

I was just going to close this thread down when it occurred to me that the complex Low that had been giving me insomnia might be over. Low and behold Google was publishing unafraid bless their rancid CIA filled socks, complex or not:

Ed,
Here in Stoke (Staffs) we have had 67.2mm, which is 120% of the total
May rainfall. All this rain as fallen during the last 7 days, which have
also produced 2 days with snow, 6th & 7th (7th - 60% ground cover at
09.00 and a maximum of just 6.5c) 4 days with hail and 2 days with
thunder, this after the first 3 days produced 32.5 hours of sunshine and
temperatures into the 70s.
After the last few months, I think the first 10 days of May have been
amazing!!

So much for all the promised rain since this complex low arrived on the
scene..

24 hours to Tuesday 6th (8a.m): 3.0mm from frontal passage previous eve
24 hours to 0800 Wednesday 7th: mostly sunny, 0.2mm from pathetic noon
(hail) shower
24 hours to 0800 today, Thurs 8th: motsly sunny, 0.5mm from brief 6pm
shower yesterday

..gives a whopping total of 3.7mm. May rainfall is running well below
average.

Basically the surface RH has been very low throughout and despite the
great atmospheric instability, any showers have been rather scattered
and brief

But here's hoping for that SW / Spanish Plume hinted at by MRF early
next week..........!

It's getting too quiet in here .... cue some action:

Just look at the Murf's forecast for next Friday - brisk SE/E'ly
surface winds, strong S'ly & divergent flow at 500 hPa, complex low
from Ireland - Biscay - E Spain :-))))

Of course, that leaves plenty of time for the tornadic supercells to
fall apart!!!

Speaking of things falling apart, UKMO seems to have grossly
underplayed the N'rn extent of rainfall for tomorrow (Sunday) ....
the more recent output is handling it better, but kudos to the
Americans - the AVN seems to be handling it very well, both 00z & 12z
runs today (pushing rain into N'rn England).

The AVN also has a boundary stalled across (or close to) S'rn Britain
for the next couple of days or so .... so from South Wales -
West/East Midlands southwards, watch out for embedded thunderies.

It could get interesting :-))

[ It probably will - just because I'm on shift!! :-(( ]

Regards,

Dave

Well the promised "interesting" winter gets under way on Monday 1st and it
really does look to be a meaty one for western Europe according to the UKMO
progs issued Saturday morning obtained from Barcelona Univ. courtesy of NWS USA.
(Thanks for the URL BTW Paul, I have now removed the link to Warwick from my
home page and put in Barcelona instead). I do not often do weekly roundups but
this one looks so interesting and I am so excited I cannot resist it, so here
goes.

Monday 1st sees a high become established over Iceland linking eastwards to the
old high over northern Norway. A trough assoc. with a low over Denmark will
swing south down the north sea giving snow showers over the Northern Isles and a
longer spell of snow over the Cairngorms. By tuesday 2nd low pressure in the
southern North Sea will ensure a lot of wintry showers in the eastern part of
the UK with sleet and snow in many places. The interesting development, however,
is a triple point low expected to run SE from west of Ireland very close to SW
England and into western France during Monday/Tues.
This poses the possibility of rain in SW England late Monday with sleet and snow
over the moors which *could* be quite heavy, giving serious problems. As always
with these features the precise track is critical and it is my view that it will
only be SW England that will be affected by this.

This low tracks into southern France and northern Italy during Tuesday/Weds
bringing a lot of rain and thunder over the Med, with a lot of snow over the
Alps, which will be good news for skiers. By this time the high over Iceland
declines a little, but with a substantial ridge to Russia the block is
maintained with warm air continued to be pushed north on its western edge from
the complex low pressure systems around Newfoundland. During Weds and Thur the
northen Isles and the western part of UK can ecpect to be dry with a lot of
clear sunshine and good visibility. However, a cold pool (sub 528DAM) persisting
over the southern North Sea (which is still relatively warm) will continue to
trigger sleet and snow showers in the southeastern part of the UK, with longer
spells of sleet or snow around troughs. It *could* also warm up as slightly
milder air feeds north from the Med. low which will bring rain rather than
sleet/snow to the low ground and near the coast.

On the broadscale what is interesting is the development of some mobility in
the Arctic around Jan Mayen which by the end of the week will pull in very cold
(sub 510 DAM) air south into Northern Russia, this combined with a continued
feed north of warm air west of Iceland will probably redevelop a high between
Iceland and Norway maintaining the easterly type, but which by then may well be
less cold than early in the week.

So to summarise, a wintry early part of the week and possibly mid week as well
in the south but a hint of
slightly milder conditions at the end of the week as the cold pool warms out.

Dig out your snow shoes, put on your chains, wrap up your granny, winter is
about to begin !!

Cheers,

Will.
