Thu 25 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. 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. High pressure will likely dominate the weather in the run up to the New Year, slowly drifting to the west. This will maintain largely settled conditions, although with an increasing chance of showery conditions later in the period. Temperatures will be below average much of the time, with frost likely where clear skies and light winds prevail.
