Fri 26 Dec Wales

Continued mostly settled conditions expected, as high pressure builds to the north of the UK. This will bring a strengthening easterly then northeasterly wind over the period, with wind-chill making it feel colder. 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.
