Wed 24 Dec London and South East England

A gradual transition to more settled conditions is expected, as high pressure builds to the north of the UK and low pressure eases away to the south. This will bring a strengthening easterly wind over the Christmas period, making it feel noticeably colder than of late. Whilst there will be a fair amount of dry weather, a few showers will still be possible, particularly across eastern and southern parts which may be wintry in places, more especially over high ground. Temperatures will likely trend below average with the potential for frost, especially in the north where winds will be lighter. Towards New Year, high pressure may become centred more towards the west of the UK, allowing a greater chance of some wet weather to spread into parts of the UK.
