Thanks Martin.


The word 'usable' springs to mind.


The GFS ensemble mean at 240 hours sums things up nicely.


No chart available for the selected hour. Many charts start at 3 hours ahead, so if you have 0 hours selected try stepping forward or selecting a later hour.


A fair few perturbations indicate a long fetch southerly. You really wouldn't rule out temps of 16-17c (61-63f) in the final days of the month.

I'll bank that.  Of course, there is the increased risk of low cloud and fog. But for now, I'll take that over depressingly wild and wet stuff all day long.

I think it's safe to say there isn't any notable cold on the horizon. Still it is only November. Winter 46-47 didn't get going until the latter half of January.

So on just that note although I know we should not follow patterns but my point is we just don't know what will happen except maybe for 


5 days out


but as Gooner says it's JFF

The only thing that is tickling the back of my mind is that last November started off as being wet and breezy then it became more high-pressure dominated in the second half of the month and you know what happened next.

But of course, like I said before, no two years are exactly alike as far as our climate is concerned. Maybe I need to take on a less stressful hobby, like drawing . . . oh, wait.

Well the girl on the checkout in Tesco,s said it was going to turn cold before christmas with temperatures down to minus 10 . I dont know where she got her information but i reckon she is as likely to be right as anyone. BigGrin

Something encouraging for those worried about a repeat performance of last winter is that the deep cold plunge into the States doesn't appear to be stuck on a loop.


Currently the HP over Alaska http://www.meteociel.fr/modeles/ecmwf/runs/2014111500/ECH1-0.GIF?15-12 is helping cold air descend into the lower latitudes http://www.meteociel.fr/modeles/ecmwf/runs/2014111500/ECH0-0.GIF?15-12.


By the end of next week this HP is shoved out of the way http://www.meteociel.fr/modeles/ecmwf/runs/2014111500/ECH1-192.GIF?15-12 and the cold spell eases http://www.meteociel.fr/modeles/ecmwf/runs/2014111500/ECH0-192.GIF?15-12.


GFS is showing something similar so hopefully there won't be that extreme temperature gradient fueling cyclogenesis in the Atlantic.

OT, and is it me of has the NWP trended more and more to high pressure pushing North later next week? If the output from just last Wednesday was to believed we were all in for a soaking and gales.

Certainly no Atlantic onslaught on the 12z runs so far. 


That high to our east is firmly in charge in the medium term at least. 


Generally dry with average temps. If we can get a genuine southerly push (akin to 00z ECM), rather than a weak SE'ly off the continent, we could see some milder temps however. 


All looks ok to me, if rather unexciting on the ground.

Surprised there wasn't a little more comment on the GFS run. Okay no cold air around but very encouraging set up:-


http://www.theweatheroutlook.com/charts/gfs/12_240_mslp850.png 


HP drifting North, some colder air being dragged round the northern flank of the HP, LPs undercutting etc. All bleeds away deeper in low res but an encouraging start if nothing else


Nice to see something different and edging close enough to the vaguely reliable range too - suggests the current zonal spell won't run on endlessly (ala last year).


The charts certainly do have a sort of 2009/2010 feel to them albeit the chances of getting them to T0 and also getting some cold air too is as usual rather 'low'.

I think I have fallen in love with the new fangled GFS. Anything to keep the Angry Atlantic at arm's length is fine by me.

Of course, it could still all change at the drop of a hat but encouraging signs all the same anyway.

GFS almost pulls off a miracle.. I know its been said alot already... but im starting to believe the hype....I have to go and check...but FI is beginning to look more and more like 2009.

GFSP has warmer uppers at times but with high pressure slap bang over the UK it could bring colder conditions than the op run, especially nights.

Surprised no comment on the ECM 12z.
However not a surprise really as the models are chopping and changing a great deal. Today's 12z ECM is very blocked from the east from as early as +72 with retrogression to Greenland by +240

A complete contrast to the dire 00z and also the more mobile outlook shown in recent days

Woah - interesting developments both inside and outside of the reliable timeframe tonight. I'll get to those in a bit - first, a brief look at the precipitation prospects for the coming 48 hours:


Precipitation accum. EURO4 Su 16.11.2014 03 GMT  Precipitation accum. EURO4 Su 16.11.2014 03 GMT


The left chart shows the impact of showers across coastal counties of The South tonight into tomorrow, along with the frontal precipitation across NE Scotland. There's the potential for those showers to train across some locations, giving locally large totals. On the other hand, they look frequent and scattered enough to give most of the aforementioned counties 10 mm or so. For what it's worth, the inland penetration of the showers is being overlooked by GFS once again.


The right-hand chart shows the impact of an area of rain moving through from the North Sea, arcing south through Sunday night. Euro4 fades this feature out rapidly on Monday morning, whereas GFS sustains it a few hours longer. The system adds 5-10 mm very widely across England and Wales.


Overall, not great for places watching those river levels rise close to or into flood stage lately.


 


Okay, I'm going to post this now to remove the risk of accidentally losing my work by navigating away from the page unintentionally. A look at the longer range coming up soon...
