Viewing it on Netweather, behind though, normally use meteociel

Fronts stalling against the block could be big snowfall for some,then Easterly winds coming back,is how it looks to my amateur eye.:D:gathering::cold:

 Edit.looks messy now,maybe bin it after 144 gfs struggling to work out where the trough disruption will be

This run is not really that different from the 12z out to 150hrs.  Uppers slightly higher but just variations on a theme really.  This is a complex set up and details of any snowfall will probably not be nailed until T24 or less

Uppers will gradually get watered down as the weekend gets closer. This will effect 2m temps and lowland snow cover.

GFS second Atlantic attack results in more snow. So far 6th/8th/9th looking key dates for frontal snow prospects.

I think that's irrelevant as there will be very little snow this weekend anyway.

As in what the weekends upper air models will show with respect to snow next week. We all know ppn this weekend is minimal.

some excellent model output at the moment and some really cold weather looking on the cards but for how long? the models seem to want to prolong the cold but the BBC news 24 forecast ended with milder air winning out toward or over next weekend, so do they see something in models we don't get to see?

Everyone ignore this post (wind up alert) 

its quite amazing how that mild sector gets squeezed the life out of over the uk between 156 and 180 hrs . You rarely see that .

Maybe they see GFS 18z?

Given how much the models have changed the short/mid term output over the last 48h I would stick to enjoying the nailed on cold for now. FI is FI and MetO still talking up a mid month Easterly.

Like the 18 gfs op ? 

Clearly thats not it but the Atlantic getting in next weekend is currently more than feasible

I think they mean milder air winning out over their London.That aside,fantastic seeing so much overall cold in the charts,especially in the new deliverer,the Northwesterly.

Sounds like a good forecast based on recent output...but it is only temporary and the cold the comes back in

To be fair, both the GFS and ECM show some milder air trying to make inroads from the west by next weekend.  However, it's been seen countless times before when the cold air is far harder to shift and milder air gets delayed.  Given what's going on with the strat at the moment, it's quite possible that even if (and it's a big 'if') milder air does push through, we may not be waiting for long until the next cold shot arrives.  Anyway, this cold spell hasn't got off the ground yet, lots to look forward to.

Depends whether it is north or mid Atlantic Nick! ECM says north and colder, GFS says milder mid. Both feasible but both not to be trusted....

This is looking good . What do you reckon @feb1991blizzard

Its an absolute snorter - you might even see the results in the troposphere at the end of the run, but that looks a timeframe outlier though, looks very early in relation to other runs and the GFS is over aggressive with these events and particularly the 18z, however, there is increasing confidence across suites now though that we will see a split SSW, see strat thread and EPS mean (not as good but still very decent).

I would like to imagine that the GFS is completely confused at this point.
