12Z runs, particularly ECMWF, have jet more veered and the difference in

For someone who was my college lecturer, at one stage, you are
displaying an extreme "sit on the fence" opinion, which would have
been ridiculed had your 'pupils' done the same on that course.

That's science for you.

I might prefer the 200mb low, which is appearently too high for winter
jet stream analysis, but 25 years worth of study has served me very
well.

200 mb is in the stratosphere in polar latitudes as you well know (or at least
ought to!).

Not always, as you well know (or should do).

I challenge you to give me an example of where the 200mb and 300mb
streamlines differ at a statisically siginficant level on the current
forecast charts, especially over western Europe.
