According to the BBC, they are still not sure if the very cold air will drift south of the UK, around south of the country, the whole of the country, or even how far West it will reach.

Basically, they don't want to look bad if they get it wrong.

Or they are simply saying that it is impossible to be sure of the weather in a few days time.

I think that is a fairer assessment of he situation.

That said, the BBC are certainly towards the conservative and less “need to make a name for myself” end of the forecasting spectrum.

I don't believe anything until the DAILY EXPRESS says so.

Until they quote AccuWeather telling us how awful it will be (and then add a Met Office spokesman suggesting something far more sedate) I won't accept it.

They did.....yesterday! WE ARE ALL DOOMED!!!

No real change in the outlook.... there is a fair amount of model 'noise' during next week, but we WILL see some very cold air arriving Sunday night, and from there the air remains very cold, and there will be features in the flow that will generate snow. The details won't be apparent until the weekend probably. After about Wednesday next week there are a few different evolutions possible, from continuation of the easterly flow, to a NE or even a low developing near the UK. Each will bring different temperatures, and snowfall potential.

The latest GFS ensemble shows the potential and variations quite well.

Just out interest , the precipitations on the right , even the boldest prediction in black from GFS only has it peaking at about 12.5mm on the 5th.

That's just a mere dusting ?

Or am I reading it incorrectly

mm would be if falling as rain. Rule of thumb is 1mm of rain = 1cm of snow if it all settles. Unfortunately the op run temps for that 12.5mm means that would be rain.

It is still saying a 50% chance of snow tomorrow when the forecast are all saying dry and colder, unless I am missing something?

I wouldn't worry about tomorrow's snow chances - we might see a few light wintry showers - the real interest is from Monday onwards. The very latest GFS has a little low pressure bringing snow Tues / Wed and a very interesting feature on Friday. BUT, although the broad strokes will stay much the same (cold) the details will change.

Just looked at that one for Friday, if that came true that would be mega flumpage and off the flumpdex charts. :eek:

Yep - 12 hours of heavy powder snow. That almost certainly won't happen, but it represents a good example of what can happen once you get the cold airflow established, and highlights how futile it is to try and forecast snowfall with any accuracy at this range.

I love Friday snow - as it gives the whole weekend to enjoy.
