Model output discussion - late November

[Methuselah]

Once the cold weather has gone (always supposing it does go!) we look to be heading into mountains of uncertainty:

   

    

Anywho, there will still be cold days mixed in with milder ones; probably more so the further north you go:

     

But largely academic, at such an extended range...

This thread is going to get busy....

The behaviour of that Newfoundland low all important. It seemingly behaves here (if you want cold) with a shape that directs a southerly/south-easterly into west Greenland

Midlands north only place cold enough for snow tying in with that low - prob high ground 

That’s -4 850hpa from somerset to Scotland Doubt the precipitation will get much further north than the midlands. Should find out about 730pm when the weather.us charts are out

Depends on exact nuances would be difficult to say at this range I think parts of the south could definitely see snow even with -4 or 5 uppers.

My general point wasn’t just for that chart anyway, this run could be a STONKER look at that near vertical WAA

[Cloud 10]

What a chart that would be for the first day of Winter.

 

shaped High as well.

 

Also NH rabbit.

Very cold ECM at 192

But some pressure being applied to the block

Sorry but can you explain further? What exactly is "amplification" ? Is the ECM better or worse on this time?

Amplification is the north south component of the jet, think of a wave - the more amplified, the greater the peaks and troughs.  Re the ECM / GEM this thread is probably running too fast to disect the T120 charts, but here we are now at T168, ECM first:

GEM is better as ridges further north, ECM is better as the whole thing is further west, on balance ECM win.

Absolute filth

[SMU]

192 is an awsome wedge with the jet diving south. Lots of Snow showers

-9c clattering into NI

[That ECM]

Please be near the mark.

at this rate we won't need @Kirkcaldy Weather 's snow pics and @Midlands Ice Age will have us on the Mosaic charts as well !

Snow showers sweeping in from NE to SW.

Pretty good evolution on the EC 12z.for any new members I'd give it 48 hours .great eye candy mind.just as a side note the 6z EC is better at 192- 240 than the 12 imo.not that it matters obv because it's all subject to change

Usually that's a word to describe the euro slug pattern that pattern above certainly isn't filth well unless you hate a cold looking synoptic output.

Indeed. If, IF, the Atlantic/Greenland High locks in with that Arctic High, then we could be locked in to a long, cold spell

Big if, of course, but the possibility is there

Edit: it doesn't on this run. I did sense that pressure was being applied to the blocking high at 192

Could you explain in more detail? 

Don't you mean excellent..

think filth these days does mean excellent, but unsure, but I'm not optimistic yet, great EC, just about right time of year now for snow everywhere, but this is well in FI

long way out, but snow day for SM and Kent folk
