Yes kinks in the isobars showing a possible trough feature moving through off the North sea.

yes, all day and all of the night.

Tbf -as regards the AZHP, and its ebb of milder sector/sectors, 

With the overwellming horizontal flow its just going to be barrelled out...

Along with miniscule shortwave-features!!

No-worrys from me on those factors..

ukmo at 120

wow!!!! it doesn't get much better surely

The Aprege continues to have the High pressure too dominant and further south than the other models. The 12z is a small improvement to the earlier version though.

Make no bones about the upcoming week.

Once the showery activity starts with the initial push of cold it will just continue to pile snow onto windward facing hills up the Pennine Chain with orographic snowfall becoming prevalent

Ukmo perfect for England and Wales, not so great for Scotland. 

Not sure about that, you can see a kink over Northern Ireland that has crossed Northern England Southern Scotland. Surly a bringer of snow

[ICE COLD]

GFS T120 very cold uppers waiting in the wings ?

That's excellent. I'm at risk of labouring a point but we want that Azores Low to scoot through into the Med quickly. Otherwise it might inflate heights over Spain and Portugal

Only ever rated the Arprege when it is showing 2ft of snow

You could see the slight difference on the GFS and UKMO 96 hour chart in the angle of the flow so I'm not surprised its a bit further southwards but still very cold though with snow showers more widely from Northern England downwards.

That is pure filth from the UKMO

[Day 10]

Wow just wow!

[❄️❄️❄️❄️❄️❄️❄️❄️❄️]

You don't see this everyday, 144 ukmo 

 

[Fingers]

What a chart that is!! Would that be better for keeping the Azores low further south at t168 and t192 and stop the introduction off the less cold uppers reaching the southwest and prolonging the cold?

Superb! The Azores Low disrupts and heads more East dampening down my minor worry about that Low moving NE. That is a stunner

[Mucka]

GFS bringing the love with countrywide snow

[Daniel*]

WOW did the UKMO just do that? The capital would be buried great flow!

[Day 10]

There's your dry Easterly!

[ICE COLD]

GFS T132 

[kev238]

To my mind, if the charts this afternoon verify then this will be a historic event for the very end of winter! 

You would have to imagine there will be a lot of snow showers and drifting!

Yes, it's far better than the already brilliant Icon

Northern England (Eastern and Central) look like it could do very well out of a feature that is now showing across most of the models. 

[SLEETY]

U.K.  meto omfg Can’t imagine conditions looking at ukmo 144 heavy snow showers drifting in gale force ,bone chilling Easterly winds is my forecast,just insane
