Im thinking PM flow longer term ...

HP nearby initially then pulled west into the West Atlantic.

 

Long way off but pressure lowers again around Greenland late on but any sign of significant cold spell not insight possibly topplers tough times this winter.

What the GFS is showing in tune with other models is the core of the PV to shift towards Siberia - still with a weaker secondary lobe N Canada, but importantly allow the trough to back westwards, allowing heights to build in close to the UK.. a flow from between north and west, rather than west and south direction of travel, with heights advecting westwards - scandi trough formation plausible.. 

As I said any polar maritime flow will be preety potent given the very cold uppers that will be wrapped within thanks to the bottled up cold air.

If we have to settle for a polar NW'ly when all said and done, I'll take it firmly with both hands!

Absolutely wretched 0z run from gfs, those blasted heights in the South refusing to budge, you can see why SM has thrown in the towel on this winter. 

 

Let's hope ECM is better, can't be any worse!

I've noticed that just now.

 

I think we have to accept the heights to our south as the new climate norm.  Climate change will push things north-wards, and that means we can kiss any decent cold winter weather goodbye.  We're faced with a future of either Atlantic storminess, or the pallid dross we've experienced so far this winter.  I give up.

Yesterday’s t240 today’s t216  and today’s t240 from ecm 0z run. Still something of interest to view Someone said “another garden path” so far this season we haven’t even looked at a window box added the perbs for fi and there are more trending the way which would be of interest. A lot of this winter even fi offered little interest.

EC looking very good this morning!!

image.thumb.png.39267db265b3ab4c173ff012daf63a24.png

GFS much flatter at day 10

In a winter were i have done a lot of moaning i think its high time the weather Gods gave us all something to smile about!

EC day 10 NH view is rather interesting..

Whilst the EC det looks much more palatable i think its probably prudent to see how the mean looks - its been pretty gash upto now but if there is some kind of signal for a bit of amplification i would want to start seeing a better mean later on..

TBF even the flatter GFS op does get some energy into Europe to allow a few decent PM shots which would possibly deliver to northerners esp with some altitude.

Pressure falling over the Med, area of High pressure drifting North towards Scandinavia, possible undercut!

Could this be the first tentative signs of a pattern change?

As expected, still little in the way of a winter pre-February looking likely. Any oscillation of the Atlantic/UK high is stymied by the tPV to our north. So GEFS D10 mean suggests temporary UK heights:

500171944_gensnh-21-1-240(1).thumb.png.bc0313470747947b6d75b2097a785104.png  D13 mean: gensnh-21-1-312.thumb.png.3e424ae433903f90b87ea9b55da132e3.png

By D13 the high is sinking and most likely back to a westerly/NW'ly zonal flow. Any tendency for the GEFS to show a NW to SE flow diving into a ScEuro trough needs to be treated with caution as this winter a bit of a false dawn. Of course, as it invariably does, the ECM D10 op produces another cliffhanger ending, that is unlikely to verify if its previous record is known. The ECM D10 mean:

EDH1-240.thumb.gif.48b4214ef187b380bec6a9d6b3069fd9.gif

GEM is simnilar to the GFS at D10:

gemnh-0-240.thumb.png.7ff75d17e3fd6960607bc397774940ec.png

So winter remains still on hold till late January for many of us!

There is some interest but its so very hard to have faith in anything that would depart us from this awful pattern that has,by and large totally dominated since early Dec.

EC appears to be more bullish but that model has burned me so many times i'm a bit sceptical.

Its very quiet in here at the moment- maybe there are more doubting Thomas's like me out there

Run of the day so far is definitely the ECM with a day 10 ridge building into Greenland with plenty of WAA. GFS not without interest in deep FI though with snow potential...

The fact is that even the Gfs at day 10 has drained the PV from its residence as does ECM

Changes are afoot

One thing I've noticed, SLEETY, is that the 00Z tends to emphasise warmer T850s, and the 12Z rather less-so...? Not that that's likely to mean much, at the end of the day...

I’ll take that. Not saying it’s going to lead to anything but there are definite signs of a change later this month. I mentioned the other day about a few GFS members moving the PV to Siberia and this shows there is a signal there now from the ECM

Still a bit worried that we get a small rise of pressure followed by everything collapsing again. GFS 00z ensembles showing this today:

ECM looks a bit more promising, but nothing too concrete to pin your hopes on. If this window of opportunity is slammed shut, then how long before the next?

I think all you need do this morning if you want to know chances for cold and snow is see at the bottom for how many are browsing!

Currently THREE including myself

Yes, better indicator than the models! I think there are some signs though, the movement of the PV more towards Siberia is certainly encouraging.
