Looks good but I don't think any of these snow charts have verified recently. The met office are certainly not having any of it. Rain and noticeable milder next week is their opinion. Until they change their tune I don't think it's worth getting carried away with what the models might be showing.

That is quite wrong. Carinthian mentioned an event yesterday  that their portal was closely watching for the spine of the country and the met refer to it on my regional forecast. Knowing the vagories of Forecasting snow, it will not be updated until at least Monday.

He does love cold but it's balanced interpretation of the model output too.

Maybe I should have specified this is from the east of England forecast. Maybe prospects for next week are better further north particularly with altitude.

I've seen many circumstances when the weather systems can't pass a certain point and then these almost always push further south.. could this happen this week??

Noticeably mild? Where? Still single digits for most next week, and this “less cold” period keeps getting watered down..

Sometimes MetO are late to change there minds and they always play cautiously. Obviously.

Starting in my opinion to show the effects of SSW,although charts are having a hard time

working out the different scenarios the east to west flow is with out doubt the form horse.

very cold air is coming probably within 7 to 8 days.

Has @Tim Bland commented on gem vs ecm similarities yet? (Not mocking, great spot BTW) 

Morning all. 

What about the problematic Iberian heights, or was that a yesterday worry?

Thinking the forecast is fluid at present.

I think that anything will appear in the 144.168 rather than in FI, so that’s where I’ll be looking.

I still wouldn’t bet any money on it though.

Gona call this now and say ecm has lost the plot for the midweek snowfall!!expect a flatter pattern on the 12z for tuesday wednesday!!!hope im wrong though

The 06z says you are .....holds the front back a little but looks like it’s just a delay rather than a big step towards  ecm evolution. Small steps may make a big step by tomorrow?

Good spot mate, hadn’t got as far as the GEM yet. It shows even more snow than ECM. My gut feeling is we get a watered down version and just a bit of leading edge hill snow. Anything is possible though. FI is day 4 at the moment !

One of these gfs runs might just show heights rising in scandi eventually, if your glass if half full...

Agreed, somewhere like Luton gets upto 6ish on Tuesday/wed and back to 4 come Friday.
