Meanwhile, back in the world of weather, there's a potentially
interesting low on Sunday....

Of course, I did give a sensible reply, which got no response!

All of the (available) models coming in to line for a system for
Sunday. Credit it where it's due, this was signalled first by the GFS
on Sunday before any others - typically I wrote it off as the usual
GFS fantasy.

The direction is the interesting one for me - similar path to the
October Storm so no doubt some warm air locked into this one which can
only aid the potential for rapid cyclogenesis.

Hi Richard, an interesting beast indeed!

Developing from an unusually far south location in association with a near
record southern extension of the Atlantic upper trough. Very warm 564Dam
air entrained in a SW'ly jet streak associated with a temporary meandering
of the polar front jet. Northern Fraqnce could be battered with storm force
winds and also SE England at risk, but wide spread of low tracks as one
would expect. On NW side of low there is a definite risk of heavy snow as
deep cold air to the north gets entrained as well, particularly on high
ground putting SW England, the Midlands and Wales in the upland snow firing
line. Most precip likely though (as usual) close to low centre on northern
side.

Exciting stuff!

Does that mean that places well southeast of the low, e.g. central/
eastern France or western Germany, could be seeing some extremely
warm, close to 20C, weather in association with this?

Certainly SE France Nick I would say. Maybe further NE too.

Yes, and I'm supposed to be visiting friends on Sunday. As a non-driver,
I have to use public transport, with some short legs on foot, so I'm
hoping that either the timing or the track of the Low will prove to be a
bit off.

We're off to Holland on Monday. Should we pack wellies or the
inflatable life-raft as well?

This one:

"Also, of some concern, the highest astronomical tide for 2 years
occurs next Tuesday, high enough to give some overtopping of
harboursides under for ordinary conditions. Even on Sunday the tide is
very large, so if the pressure does drop as much as predicted there
could be some real problems.

The only good thing (as far as the coast of Cornwall is concerned) is
that the rapid development & movement of the low means the swell
shouldn't get too large. (It's not currently forecast to be that
big).

It's when deep depressions move slowly north from Biscay you get the
really big (20-30') swells developing, but it will be rough. At the
moment Biscay and southern Brittany seem to be the main areas of
risk.

Certainly one to watch."

I don't know which phase the moon is on the 28th but of course it is a
coincidence that everyone is attracted to it without open discussion
of the fact. But that is a given on here.

Unless one is interested in the sea or astronomy the state of the moon
will be unremarked.

So much was done in Victorian times to prove the moon has no influence
whatsoever on the weather it would be silly for anyone sensible to
take another look.

And they are quite right too, depending on averages as they do. And
then there is the idiocy of trying to insist that the coincidence of
Spring tide affects the column of air in statics.

As for my promulgations. I can't offer an explanation. Just that there
is a link.

Have you ever come across the work of FitzRoy on the subject of the
barometer. I really must get around to publishing my edition. I swear
it is very interesting.

Is that an 'official' speed? I thought 100+ were Northern France
