Here is a summary of the NWP output for noon on Tuesday.

A change is on the way, with pressure rising markedly over the UK and, more
notably, over Scandinavia. Tuesday is the transition day, as pressure builds
strongly across the UK.

Actually, the transition starts tomorrow if not today as the spell for
the next phase is introduced.

There's likely to be some rain for northern and
western areas and that applies for the rest of the week too, as frontal
systems attempt to move in from the west. There's considerable disagreement
about the positioning and intensity of the high to the east or NE, with
SE'lies or easterlies more likely than NE'lies. Despite the possible
southerly component, it won't be as warm as it has been recently for the
bulk of the UK, with the possible exception of the NW of Scotland.

Anticyclonic to the west, probably the wrong side of the Mid Atlantic
Ridge, leaving conditions in Europe to dominate:

Dominate discussions and the hopeful fretting, that is.
It is a confused spell -or one that condemns me to perdition, for now.

BTW, there is a quake due when this catalysis ends.

I don't know why I put off looking at the North American surface
pressure maps for so long. I did make an attempt to understand the el
Nino phenomenon once on a private weather forum.

But that was before I realised the way they decide a call is based on
statistics and involved a temperature gradient in the sea (FFS!) And
that temperature difference was a matter of some half a degree
centigrade.

According to a three day glimpse of this:

http://weather.unisys.com/

The standard model for a phase whose time is about 5 o'clock is a
stream of Low pressure crossing the States from the Pacific at Baja to
the Atlantic at Labrador.

The corridor for this low is a stream running NE from LA to the shores
of Hudson Bay and Tucson to Philadelphia. (Shouldn't that be
Philodelphia?)

There are two regions of High pressure bracketing this stream. One
from the NE seaboard of the USA through the middle of Texas. And one
from the Hudson Bay to Southern California.

As a guess I'd say that the alternative (when the time of the lunar
phase is about 7 o'clock) is a Low pressure system over Florida and
Georgia in an arc down the banks of the Ohio and the seismic events
are similarly settled at some 5.5 Mag max.

I suppose it would be too obvious to suppose that arc continues on
from Cincinnati to Baltimore. Makes a nice elliptical pattern though.

I have no idea where the rest of the air systems would lie.
