Model output discussion - here comes the beast!

[Chris.R]

The GFS 06Z...OMFG......that’s all I’m going to say!

Remember THAT ECM a few years ago?  I don't have an archived chart to hand, but damn the current output must be strikingly similar, and at short range too!

Look at that long-draw easterly! Hubba.

GFS @114hrs.....to me a better angle/depth of WAA up into E.Greenland/Svalbard region. Looking peachy....

The beast is coming at t129 

[Altostratus]

That is one crazy ICON run. At 180hr there is pocket of -28C 850hPa air almost within touching distance of the BI!

Ok I don’t have enough superlatives for this 144 chart UKMO

Just stunning! It makes all these years of model watching worth while!

Looks fairly dry with a few scattered snow showers. 

Albeit it does not take into account convection.

UKMO 144

UKMO is basically pornography.

And the beast is in at T132 ?

[ukpaul]

Some concern still on the high inflating to push PPN too far south for most of the country. Would be happier with a northwards correction quickly after this at 144 from the UKMO.

The high is being pushed west, not sure it would be an issue a few hours later!

UKMO/GFS/GEM at day 5

      

GFS and UKMO look fairly similar with the cold air streaming in from the east. The GEM really blows up the low heights to our east which tends result in the cold air barreling over itself until it eventually reaches the UK.

Day 6

      

Again slight differences between the UKMO and GFS but roughly the same idea, the GEM again tending to complicate matters with that deep cold pool and we end up later on under a complex cold trough.

The GFS and UKMO are fantastic this afternoon with that easterly fairly clean and controlled meaning several days likely of bitter winds from Siberia before we look possibly to the north to continue the cold. The GEM is still good with plenty of snow moving in under those deep low heights and again retrogression is the theme later on.

UKMO has bitter air moving into the east by Sunday lunchtime!

 

[kev238]

Well we have the 3 models so far all on the same hymn sheet with deep cold arriving sometime between Sunday afternoon and Monday morning.

Lol that looks like Mr Burns out of the Simpsons.......seriously though -16’s about to cross the North Sea  

[Southender]

Well that's another stunning 12z set in the bag in the reliable. How many more do we need before we can break the silence to family and friends. Fun and games begin Sunday afternoon/eve

Precipitation at this point probably limited to The Wash and further south, but there's plenty of instability and cold upstream for T168/T192.

GFS 12Z now not far away from the ECM 00Z

[tight isobar]

I need this in my life..(coldie)...

Quite simply majestic...
