[Snowly does it]

A change early on - more chance of coastal ppn for the East Monday night into Tuesday?

[PB22]

Morning all, interesting 06Z GFS so far (up to T+54), with suggestions of the general synoptic pattern being slightly further west once again. Intense cold building over Scandinavia, which is what we want to see.

ECM concerns me this morning, and it must not be discounted. Still huge differences between the models as early as T+72, so it could go either way.

[Matty M]

Looks like a few snow showers in Eastern England from the initial easterly on Tuesday evening..

Slightly less pressure rises in Scandy at 72hrs..

I'm still loving this run the cold is deeper and much further southwest..

Much better for prospects of breakdwon snow.. pressure beginning to rise at 78hrs

Its a cracker so far - protective bubble of -5 air holding at T72

[Matty M]

Snow pushing into Ireland at 90hrs.. Pressure upto 1020mb.. Loving the orientation of the approaching LP.. could be hours of snow in Ireland.

[Snowly does it]

The Atlantic will have to work to get north and through that - look at the heights further north - flabby but more extensive..

[Matty M]

Could potentially blow the block abit more though... but at 90hrs its a nice run :lol:

[PB22]

Fascinating GFS 06Z up to 90 hours. I'm really beginning to think we *could* be on the verge of a major cold spell from the east.

[tom_f123]

still the bbc forecast not mentioning past tuesday lol i think its john hammond doing the countryfile today glad its not everton fox lol

[Snowly does it]

OK, i am no expert so a question here - lp over East Europe propping up the Scandi, fairly S tracking jet... some potential here for the Atlantic to undercut the HP? Draw in a more robust Easterly?

[Matty M]

Heavy Precip struggling into western Britain..

Snow across northern and northeastern Ireland.. just about here! :lol:

Wonderful to watch isn't it.

What with the ECM output and now the GFS currently continuing the trend of rising heights, throw in the UKMO this makes brilliant viewing.

I liked your comment last night that when models struggle as much as they are you know something is brewing ( something like that anyway).

[WINTRY WALES]

How far will it travel into the uk do you think before being halted by the high to the east???

There is plenty of potential, yes. Its still to early to be sure of what will happen, virtually any option is still a possibility.

[Matty M]

Heavy snow into Britain.. abit borderline pour moi.. but ya never know..

[snowmadchrisuk]

that low from the atlantic and the ppn is so heavy, I think on this run it might make it across the country. Winds could also be a problem come thursday. I think the battle ground is back on.

[snowdrifter]

Precip now down all the west/midlands. Maxes of 1/2 - looking very good so far. :lol:

[Matty M]

Less intense Scandy high thus the Atlantic might make it in easy and there will not be a rensurgence of cold from the east..

Thing certainly still up in the air so to speak!

[PB22]

Possibly, but keep an eye on those rising heights to the west of Norway. :lol:

[snowmadchrisuk]

6z has light snow progged for central england as far west as wales for tomorrow night, yay.

[snowdrifter]

Heavy snow into Britain.. abit borderline pour moi.. but ya never know..

Possibly, temps could just be on the marginal side for lower levels like mine, but anyone with some elevation should be fine I would have have thought.

[TEITS]

Friday could be fun.
