thay are looking as if they could re-flip in the 6 to 15 day period
outlook. A few things are coming together now that will seem to aid
the cooling process in W Europe over the coming days/weeks.

The models are such that this sort of situation becomes mathematically
unstable with just the slightest change to just 1 or 2 aspects of the
variable dataset. The deterministic output will consequently flip-flop
for a while (ie now), before the true scope of the forecast becomes
clearer mathematically (more constant model output/outcomes). This
time span seems to be in the next 6 to 15 day period.

It will be interesting to see if your ideas come to fruition. There is
nothing on the models to suggest this, but models can change
spectacularly in the course of 4 days and to be perfectly honest, I
wouldn't expect them to stay the same as what is being shown at T+300+
either (I don't think we will see any great cold at 6 days though).

I note that you haven't actually said how they will change and what
new synoptic set-up will produce the cold, or how cold it is likely to
get, or at what actual time, apart from sometime in a 10-day period,
we'll see this change. I guess you are keeping your options open on
those. *))
