Dont know if this was posted last night  but 120h fax suggests snow for the north and south.

Not liking the look of this low's track, nor the uppers profile.

T+168.

looks like a breakdown for the south on the 06z, but a snowy one 

No, me neither. Think I may have spoken to soon in reply to Rob. However, it's just one hand of 20 so no doubt other solutions will be available.

But the push of milder air looks slower and looks like it may struggle to get far North (at +174)

Remember remember the surface parameters.

This deep cold continental influence is not normal service.

EDIT - Looks like we've dodged a bullet (in terms of a milder incursion) by T+180. Very close though.

I'll take that thank you very much.

Looks pretty bonza to me.

People are worrying too much and getting a bit tetchy today. Understandable. 

This chart is at T+120 http://www.wetterzentrale.de/maps/GFSOPEU06_120_2.png

Absolutely awesome. Bands of heavy snow pushing in from the east affecting many areas.

Looks fantastic to me - snowmaggedon for the Midlands :-)

Looks fine to me, snow all the way, and then it moves away East.

Agreed - snow almost anywhere from Monday onwards. Fine detail won't be apparent until nearer the time, but you can just envisage the snow streamers which will set up as very cold unstable air crosses the North Sea.

Not a fan of snow then?

Amazing London ensembles this morning and I screen shot it to save it as to remember as this is the best one I ever seen with confident to reach -15C and as low as -17C so more likely to be around -16C as the result.

It takes longer to render all those hashes for the snow.

Yes... and as Joe posted, remember the surface temperatures will be lower.

There will always be this risk and scare moments when we try and go for the magic substantial snowfall and to remain on the cold side.

A risk worth taking? I'd say yes.

The scary part is that we have many more runs to see how this plays out and in the process will suffer lots of weather-related anxiety 

Whilst very much aware of the limitations of the GFS ppn forecasts, they have a persistent signal for that wide band of heavy snow to move northwards late next week. I'm hoping for a snow-induced early dart from work next Friday - but my daughters are at a big cheerleading comp in Sheffield on the Saturday, which should be an *interesting* drive.

Deep in FI but it is not until Sunday next week that some milder stuff makes it into the far SW
