We're heading firmly into last minute territory now - if you have shopping left to do, it's time to crack on!
The weather is on the change, with high pressure moving in to bring drier, colder conditions for Christmas, but we're not ruling out the chance of snow in places, yet. At closer range, there's still some rain likely at times as the great Xmas getaway gets underway this weekend.
Santa Shaker! ⛄
We're settled on the broader picture for Christmas day now - high pressure start to make its presence felt on Christmas eve, to be centred somewhere to the northeast or east of the UK by the 25th. That's going to leave us with a lot of chilly, settled weather, with the best of the sunshine probably further west, but the exact position of the high is still up for grabs, and it's that which'll define that detail, along with the risk of seeing a at least a few flakes of snow here and there.

The Met Office model above is one of the models that wants to take the high a bit further north at the moment, which allows some colder air to be pulled into the UK - if this version of events played out then we could well see a bit of snow here and there.

The ECMWF model (above), has the high further south - it would still be chilly at the surface, but the air aloft wouldn't be cold enough to support snow - so anything falling from the sky would be (drizzly) rain.
Just now, the slightly less cold option is the most likely, but only just - and it's something we'll certainly continue to monitor, with a view to firming the forecast up over the coming few days.
Give Santa a shake to find out the current chances of seeing at least a flake of snow in your region and check in Saturday for the next update.
