Model output discussion - Post SSW - Will it turn cold?
LRD replied to Paul's topic in Forecast Model Discussion
I agree and this isn't based on any scientific analysis at all but I think not only will this happen but with the added bonus that it will be brought forward by 24-48 hours The models will start to accelerate the Easterly over the next couple of days -
Model output discussion - proper cold spell inbound?
LRD replied to Paul's topic in Forecast Model Discussion
That's why I said that it doesn't look good on face value Look at all the greens to our north. Blocky Onto the 12z run of the GFS and BOOOOOOOM... http://www.wetterzentrale.de/topkarten.php?map=1&model=gfs&var=1&run=12&time=312&lid=OP&h=0&mv=0&tr=3#mapref This would result in the coldest February spell since 2009 or 2010. Possibly even 1996 -
Model output discussion - proper cold spell inbound?
LRD replied to Paul's topic in Forecast Model Discussion
A cold spell seems inevitable now Even this from the 06z run of the GFS... http://www.wetterzentrale.de/topkarten.php?map=1&model=gfs&var=1&run=6&time=288&lid=OP&h=0&mv=0&tr=3#mapref ...has a lot of northern 'blockiness' even though, on face value, it doesn't look good for cold weather -

Even without blocking it looks like the polar vortex might threaten the UK from Christmas. Jan 1984-esque If we can't have 'classic' cold I'd love to see some of those runs - that have the PV close to or over us - verify to see what that would actually produce on the ground (rain, snow, gales - at least it'll be some weather to talk about). With, hopefully, the Az/Euro High pushed way south and south west too- 2,328 replies

Notable cold spell? Not for me. It was standard really. If we're relying on a SSW and Glosea is losing the signal for one in January, it's a worry- 2,328 replies

Of a massive 5 days, yes. Legendary stuff. OK let me ask the question in a different way which might negate a sarcastic response... have we ever had below average winter months without a SSW playing a part?- 2,328 replies

LRD replied to Paul's topic in Forecast Model Discussion
I should know this but can NW Europe have a cold spell without a SSW? Or have SSWs been proved to be the be all and end all? Surely we've had cold spells without them? Glosea is a good model so this is disappointing news- 2,328 replies

You've posted a chart from Dec 1987 there dude Presuming you meant to find an image of Dec 1986 to demonstrate what was happening before that glorious fortnight in Jan 87?- 2,328 replies

With respect don't those links just show blips in an otherwise upward trajectory of temperatures - especially in the Arctic? https://www.metoffice.gov.uk/research/monitoring/climate/surface-temperature- 2,328 replies

So the arctic isn't warming then? Is that what you're saying? Or have I misunderstood? As I say severe cold or not (in the UK) a warming arctic is a worry- 2,328 replies

Model output discussion - winter proper underway
LRD replied to Paul's topic in Forecast Model Discussion
But, as I've pointed out earlier on, the high has shifted northwards compared to yesterday. If it continues to do that we might find ourselves foggy and frosty. Admittedly, at the moment, it does look like it's going to settle at exactly the right place to bring us a whole load of nothing. I'd rather it be right over us (possible frost and fog) or way south to let in some lively Atlantic interest. If we can't have snow/ice/frost, let's have some heavy rain and gales- 2,328 replies

I'm not talking about the effect, or not, on our winters Feb. I'm worried about the planet. Having an arctic region that warm is massively worrying. But I'll leave it there as we're going off topic- 2,328 replies

Model output discussion - winter proper underway
LRD replied to Paul's topic in Forecast Model Discussion
A clear movement of high pressure northwards compared to yesterday's model runs. Too early to say 'trend' but if subsequent runs continues to nudge that high north (it was over France on yesterday's ECM for example), we could well see a cold, frosty, possibly foggy run up to Christmas via an inversion. Depends how much cloud gets caught up in it I s'pose.- 2,328 replies

Stretching from Spain to the Eastern Seaboard of North America, the Azores High is absolutely huge and bloated on that chart. Like a sumo wrestler who has really let himself go. The '5 bellies' high- 2,328 replies

Mind might be playing tricks but didn't GLOSEA call a cold winter back in Nov 16? That's what triggered all those wintry long rangers that METO were coming out with late autumn/early winter last year I agree with your comment, in general, though- 2,328 replies

Model output discussion - winter proper underway
LRD replied to Paul's topic in Forecast Model Discussion
Yup very true. To be fair to GLOSEA, though, I think last winter was the first time you could say it bust. And, at times in January it was a near miss for deep cold for the UK. I know a near miss may as well be a massive miss but, in terms of forecasting global weather patterns, it wasn't that far out. They've got to keep pushing and testing the science though.- 2,328 replies

LRD replied to Paul's topic in Forecast Model Discussion
I'm guessing the models that the METO have access to (but that we don't) have been seeing something blocky as the METO updates have been hinting at it. But, unfortunately it keeps getting pushed back. The blocked theme was first touted at Christmas which would have been marvellous. Now it's the new year- 2,328 replies

Model output discussion - winter proper underway
LRD replied to Paul's topic in Forecast Model Discussion
The latter stages of the ECM are a bit of a horror show for those who want to see cold BUT ...there are signs that pressure is building to the NE in FI and the seemingly inevitable mild spell is getting pushed back even if it is only by a matter of hours I don't mind a spell of Atlantic weather as long as it's lively and interesting. The later frames from ECM will be both mild and dry for the south. Or, to put it another way it will be BORING for the south- 2,328 replies
