Model output discussion - into 2018

[Johnp]

As usual GFS manages to find a 50 mile diameter area of low pressure over Norway which manages to block a 2000 mile area of High pressure from advancing.

You miss read NWS post. He was referring to the GFS in general not the 06z. 

I was not responding to NWS it was a general Observation and not just Today,Happens all the time,Just wish some folk would wait a bit longer before posting.and let the run develop.

The GFS is still having absolutely none of it though, and given what happened just a couple of days ago I'm not letting myself get excited.

Very wise indeed it trumps the others but only because none of them have a very good handle on what in reality is going on !!

[northwestsnow]

Nope. 

GFS not really interested again- any easterly is about 2500 miles away in Russia!!

It did make a big move towards it in the early stages of the run, then managed to concoct a way to derail it.

Indeed Teits

No denying the 06z is swinging towards the Euros.Just wish that some would let the run develop before posting.

C.S

then again we've been told ad nauseum to ignore the 06/18z GFS as it's pig-swill.....but wait! if it shows cold, then it's the best thing since sliced bread...  ........that's why new and old members alike get confused, they get inundated with contradictions.........

still,, in terms of the output itself (and to make this post on-topic) I'm following TEITS's posts with interest, he initially and correctly posted a few days ago that this initial easterly would fail, a correct prediction so a big tick in the box as one has to get the initial solution correct to have any chance of offering a remotely accurate medium term forecast prediction 

[northwestsnow]

well theres no dressing that run up- its garbage!!

Hopefully,its wrong.

Hmmm.small steps forward early on I guess but the problem is it could end up as a holding feature without actually producing any wintry weather! !! Maybe something from the nw may be more productive .btw do you know what 850s are required at sea level in a pm nw flow for snow.my brain oa a bit fried this morning tia

I'm not sure mate- i'm not throwing in the towel on an easterly yet- gfs6z is crap though..(out to 216hrs).

I would disagree, upto t120 it's a good step forward. IF it does the same later FI will look very different.  But heyho all part of the fun of discussing.

Can someone post some charts please. Lots of one line comments and none the wiser.

That's what imo is the step forward. Look at the block to the ne.

Since when has GFS been able to display a high degree of accuracy at T+216 anyway?

Go on metiociel or look on netweather to follow the charts.it will make things clear in regard to the posts on here

I agree- i was just commenting on this run in isolation, not saying its correct

I also predicted it would fail, and I'm predicting any potent Easterly much before months end will also fail

[northwestsnow]

whether we like it or not GFS6Z looks exactly like the meto update yesterday sounded- ie no easterly to speak of and unsettled with perhaps snow in the north at times amongst an Atlantic dominated pattern.

[Scandinavian High.]

00z a westerly flow . 

 

Gfs 6z we are cooler south/ easterly flow next weekend 

 

The trend is maybe westerlys do not get in end of next week something cooler from the east..

None of the models do . Exeter have problems with anything past 7 days along with most professional forecasting agencies

Indeed, in my opinion, the viewer should always be looking at charts beyond 5 days with a high degree of scepticism, whether they are showing cold or mild.

FI is at 90 hours or so. Anything after that is anyone's guess. NWS don't let yourself get hung up on op runs like the 6z just sit back and enjoy the ride.

Yes im thoroughly enjoying it

But as i said, 6z is a perfect fit to exters update yesterday- naturally im hoping the update today is more positive

Predictions are one thing but backing up your reasonings behind  your predictions as teits has done is priceless.

 

Maybe give a balanced view on why any potent easterly will fail because imo anything past 96+ at the moment is dubious. There is a wide range of options on the table which is why i refrain from calling any option going forward at the moment.

I'm with Feb at the moment- i'm leaning against an easterly anytime soon, and the reason is GFS/GEFS AND EC/EC mean is against it too.

TEITS may be right, i'm certainly not saying anything is set in stone, but imho, if he is predicting an easterly, he will be wrong unfortunately.

But, as i say, things could change.
