You're clearly not reading the charts or looking at met data, so do your figures come from an app? If so, which one?
The BBC show a max of 4 on Sunday, and no higher than 6 over the next 10 days. Where on earth do you get 12 from?

His imagination?

There's not complete model agreement, but Monday is looking potentially snowy for a period, as the Atlantic fronts push in against a cold airmass over the UK

To provide some context. The UKMO is consistently showing High pressure remaining to our NW even by Monday:

With Low pressure to the South and East, there's HUGE potential with this setup.

GFS has been very keen to bring the Atlantic steaming back in but even then it's been showing a snowy breakdown as it struggles to shift the cold surface air:

Which gives THIS precipitation:

Is it me or is that giving us a possible and considerable flumping scenario?

Papa, does high pressure in winter mean cold?

Yours confused of Burgess Hill.

Yes, often it does. A lot depends on the exact positioning / orientation and the 'source' of the High. So, a high which developed over Scandinavia or similar will contain a cold / dry airmass, which will deliver clear skies and sharp overnight frosts. A High that moves up from the SW will bring a more humid airmass, so it may well be a cloudy high, with moist air trapped under an inversion.

The orientation will be key if the High isn't directly over us, so one centered to our South will allow mild air to flow over the top, limiting the cold potential, whereas one which is able to pull in air from the near continent will be much colder.

It made me laugh tonight the BBC weatherman saying 7 c this very week as very cold. Unfcking believeable. Give this up now until next year

What is this obsession with snow? its water turned to icy crystals

A holiday to Greenland should solve this problem.

No, they said it will feel very cold. Big difference.
Check out these Met Office 'feel like' temperatures for the coast this weekend. Minus 4 up to a maximum of zero at the warmest point of the day.

It will feel very bloody cold, you simply cannot argue with that.
