I have never said that this wasn't the case.

Now Freddie, you only have to scroll back:

The high pressure, which was centred to our east before the weekend
No it wasn't - it was directly over us.

and:

Yes it was. Look back over the charts and you'll see that the most easterly
point of its progressive journey left its centre to our east. Look
back at the charts.

I did look back over the charts - but only to double-check before I made my
assertions, as I follow them in real time too.

2. Between the 12th and the 16th, did the high pull back to sit to

our SW? Again, you've maintained that this never happened, but the

charts clearly show that it did.

I'm sorry but I don't see that in the charts.

What else can I say? That's exactly what the charts show between the 12th and the 16th. You linked to the charts and the charts show retrogression between those dates. It's as clear as a pikestaff.

Additionally the upper

level dynamics (i.e. the existence of a progressive pattern) do not

support regression of surface features.

high formed to the south west. If you look at upper air charts

for

the same period,

A link would be good. I'd like to see them.

Can anyone supply Paul a link, please?

Freddie; I feel you are trying to do this completely from memory. Nowhere before have you mentioned upper air charts and may I suggest that your memory of what happened at the surface is not correct. My evidence for that is that your memory told you that the high did not progress to sit to our east - which it certainly did, for a full day on the 11th.

I do follow these charts on a daily basis, Freddie and I comment on them and forecast from them on a regular basis. Are you sure you are remembering this sequence of events correctly, as the archive charts simply don't back what you are saying?

I don't think this particular forecast of mine in the OP was perfect at all, as I've said; the cold air and snow showers on the hills didn't really get here until the 21st, as the pattern was not as progressive as I expected it to be, following the retrogression of the high, but the high did progress to our east on the 11th and it clearly retrogressed, pulling back SW, to the 16th. After that, I expected a fairly rapid incursion of colder air, which was delayed a day, or so.
