Very confused here guys?

Compared to what it was showing this morning the high is under attack from NE a lot more. Still good just not as good as it was earlier hence the tern 'downgrade'.

Timings are a bit off but there are still differences. The 0z had straight easterly across much of europe, 12z looks a bit sloppy.

If people explained their reasonings behind their presumptions it would make the thread a lot better to those who dont understand fully whats going on.

 

What use is close to brilliant and downgrade all within 3 posts for the same model, same timeframe as doctor pointed out.

 

Justify your thoughts and helps everyone learn better or look at the reasoning for your comments good or bad.

Under attack from the NE? Eh?

That doesn't make any sense.

Nothing wrong with varying opinions, be very boring if we all just agreed lol

UKMO 144 isn’t a downgrade, block edging west along with cold uppers, Atlantic pushing up against the block. Will it disrupt? Guess we will have to wait for the next most important run of the winter the 00z 😂

It's because some people write with such authority...when in fact they don't know what they're talking about.😇

So i take it as soon as that first disruption from the atlantic gets resolved in the 72h to 90h time frame any output after that is likely not to be correct? Depending on which model is on the money regarding this!

I explained my reasoning.

If you was to follow on from the 0z with 12z you would notice that the block is under more pressure and the winds along the SE of the high are not straight easterly like the 0z. Good chart but way to close to the knife edge where the 0z was a lot more safer.

I could quite easily believe the UKMO over the GFS, but over the GEFS is a big ask.

I will put this out there, the ukmo 12z isn't a downgrade, it follows on well from it's 00z and is poised for a mexican standoff between the atlantic and the cold block to the east which is so tantalizingly close to drawing much colder air into the uk ( just across the north sea!) the drama goes on, the plot thickens!:):cold-emoji:

Look at the jet forecast, it'll stop egg on face later. The 06z was poor because it took it further north and barrelled through the UK whereas before it hit the south only. This time, for the 12z GFS it's even further north so NW to SE is becoming W to E and that's a big step backwards by 162h.

Have we had cross model agreement on anything this winter? Apart from a mild Xmas day?

Why would you believe it versus a high res operational run, but not against the 20 low resolution patterns spewed out four times daily?

Let battle commence!

According to the UKMO update, they are not onboard with the block winning. I know this is subject to change, but their lack of support for any extensive cold concerns me. Remember *some* of the models were showing cold uppers for this weekend and it was watered down to a cool weekend with daytime temperatures actually hitting 8C in the South. 

 

Better GFS though a suspect a battleground is setting up with, maybe, some interest before the Atlantic wins in later runs.

Well i can see an argument either way on ukmo, the block looks strong, but i'm not seeing enough Atlantic energy going under.

I'm not at all convinced an easterly will be coming at 168..

GFS looks carp, again..

Id suggest we need the pattern another 200miles west on ukmo, the trough which we would need around Italy is actually near crete.

The pattern is the same as the 00z run though, that's the main thing.  You're unlikely to get two consecutive identical runs (especially the UKMO 144 charts!)

Personally I think to the east is should be nicknamed as a "Sucker's High". It will suck us all in with "will it or won't it" with the models and before you know it about a fortnight of winter has gone and nothing to show for it except exasperation, hair pulling and "I won't fall for it next winter" at the end of it.

The UKMO has been remarkably consistent with the Scandi high  but it has to be said that even that doesn't bring us an easterly. The easterly at 144 hours stops in Germany and even there is it more southeastely than easterly. 

The low pressure between Greenland and Iceland is too deep and too round to allow any easterly for us. It will have to be shallower and disrupt southwards somewhat. It may happen is subsequent runs or it may not. As things stand I don't think we are closer to the easterly than this morning.

imo you won’t see the Antlanic push through, that is a pretty robust block and would take some shifting! If it turns out as modelled that is.
