The Met Office don't share your confidence. This from Essex Weather Cent "Yep, the cold spell begins! As you've probably noticed the Met Office jumped on board today with the long term cold outlook. Both MOGREPS and other internal models show a Easterly influence (on and off) across Southern England until Mid February."

I don't see how they can say that with any confidence at this stage.

Good luck with that one!

I regularly read the Model Output thread on TWO and the gist I am
getting from that is that over the past week or so the models hwve been
flip-flopping like mad are hard pushed to call anything at 5 days, let
alone 10.

Judge the forecast at outcome. Not now!


I'm not 'judging' your forecast, merely expressing surpise that you ould
chose to issue at a time of such uncertainty.

I'm not in the slightest bit interested in what is being said on the
model output threads on forums.

So you know best obviously.
Fair enough, we will see on the 23rd.

Best way.

PS I don't 'know' anything, Col. I just have 80% confidence that this forecast will achieve outcome. Looks OK tonight, but there's 9 days to go.

Indeed it does, things seem to be going your way so far.
But there is no point in giving a running commentary on the inevitable
twists & turns prior to the 23rd so I will leave it at that for now

It looks like it *could* all hinge on what the low (FAX chart L1010 at 120Z) on Monday does. Will it stall, turn left or turn right? MetO are still saying not to look beyond 120Z

Blimey a zonal forecast, how does the idiot do it. Incredible and against the whole meteorological historical data grain.

Looking pretty good at this distance. Depends to some extent whether the European high is positioned over the UK as to full accuracy, but models are not in agreement on the exact position at all. I favour a position to the south of the uk, perhaps with a ridge over us. What they are in mostly agreement about and have been since the 13th is that Atlantic air will cover the UK on the 23rd.

This one was pretty much bang on. You could have put your trust in the model output from 10 days ago, to have shown you what the weather would be like today. It certainly is possible to use models to forecast at 10 days, on occasions. Much of the time, however, you can't trust them to do so.

After this re-establishment, it's looking zonal now to the end of January at least.

The people on TWO that you were reading were wrong, I'm afraid, Col. Those people simply do not know when to trust model output and when not to - especially when there is a sniff of cold. It tends to addle their brains. 😀😀
