15th Jan (19:46) So this is the last day of a most interesting spell.

Unfortunately the next one is somewhat similar, so expect very little
change in the GEM and GFS charts.

11:37 is as near to noon as 19:46 is to 18:00 as damn it is to
swearing. And the expected situation on this chart:

at these times is:

A standing Low Pressure area situated somewhat to the left of the
Great Lakes.
With a complex set of High pressure areas trying to break through from
the west.

However it isn't as cut and dried as all that. Consider:

http://meteonet.nl/aktueel/brackall.htm
And all the northern hemisphere seems covered in a double Low pattern
that is balanced by a double High situation that is a macrocosm of
what this type of spell should ordinarily be producing over the UK.

This spell and the next is normally one where two Highs and two Lows
are counterpoised around the UK with the centre of the effect being
known as a "col".

Usually the situation is speared by ridges or troughs from the
dominant air mass.

I am not sure (too inexperienced) to say how unusual this present
situation is but in lieu of a decent hurricane at lower latitudes, I
imagine this pattern is a decent substitute that explains the present
situation in Britain:
Flood Warnings.

Something similar on the Canadian-US border:

where winter weather watches are in effect. (Strong winds, snow and
ice.)

And no sign of things changing much on this:

Which is tantamount to saying that with an East Siberian High, a North
Pacific Low and and Arctic Low in situ; no Highs on the US mainland
are going to find their way into the North Atlantic and.....
No severe earthquakes are going to trouble the Aleutians.

Or not, as the case may be.
