[bluearmy]

Not sure what is less likely, the stalling of the upper low over Poland or the 1060mb high over n Sweden !

T201 GFS 6z. The cold and snow is coming closer

[Singularity]

So I suspected the cold arrival could be brought forward but had mixed feelings about that after the GFS 00z compared to the slower but steadier ECM and UKMO.

The GFS 06z is however showing us that if you get a good wedge of higher heights extending N from the UK, the cold feed can be directed back further S even with the continental LP having had more time to develop than in the slower scenarios.

If the 06z can hold steady we’ll have both a faster and a slower route that both result in a lengthy spell of deep cold. Not a bad way to start your Sunday if like me it’s your lie-in day

Stunning and wow 

[ICE COLD]

These stunning charts just keep on coming - GFS 6z 216hr 

[tight isobar]

Not only is the cold now running like clockwork-as a reliable source, but also the dynamical refer-ie, on a clockwise counter scale the cold just keeps aligning- and punching into europe as a whole.......

This could be a very prolongned-fridged spell we are about to walk into!

And something like most have never seen!!!!

It is odd to see the low just come to a standstill then inch its way toward us.....cant complain though

[Day 10]

Winds begin to strengthen, snow showers begin to move inland.

PV starting to make the journey east over the high now, so retrogression of the high to Greenland is incoming.

Morning folks. Been following this forum for many a year and this is the most excitement I’ve seen from even the most knowledgeable posters. Over the last couple of days there’s just been upgrade after upgrade with each run; something tells me that we may actually finally hit the jackpot. May we all get our snow fix. Bring it on!!!

[WalsallWeather123]

As long as the heights stay where they are on the GFS 6z we are in for a memorable cold spell

[Banbury]

What a chart this is 

[Nick F]

Here comes the snow maker from the east for Mon 26th

Outstanding 06z GFS, that upper high is nearly perfectly placed on the 06z GFS and the shape is just unreal. Close to perfection!

Miles better then the 00z GFS,night and day. (though as has been said, the 00z GFS is still in its own right a pretty good run!)

Wonder what the ensembles will suggest..

[SLEETY]

Unreal charts snow be piling up in the east with towering snow drifts by now I would imagine and severe windchill,

[chionomaniac]

What's better than a cold bringing Scandi 1065 High?

A reloading cold bringing Scandi high. That's what!

 

[Frosty.]

The Gfs 6z is like that movie, the day after tomorrow.. Truly Epic stuff with blizzards, severe drifting, severe wind-chill and pipe busting penetrating frosts..sensational!!

[ITSY]

Wow. Speechless again. Pretty much perfection from a cold and snow perspective. Hope the GEFS continue their downward trend from the last 3/4 runs 

[winterof79]

So ECM says

GFS says

I think they've made up........... METO update requested asap please 

NAVAGEM on course

GEM doing the job
