Fri 27 Dec London and South East England

Boxing Day weather will be characterised by mild, cloudy conditions for most, with bits of drizzle in places and perhaps some more persistent rain in northwest Scotland. This sets the scene for the next few days too, with an area of high pressure becoming established across much of the UK, probably centred over or just to the south of England. The highest chance of rain and strong winds will be in northwest Scotland, with many other areas predominantly dry but rather cloudy, although more settled conditions may well extend to the northwest at times too. Widely mild at first, perhaps exceptionally so in some places early on, but temperatures probably return to nearer normal by early January. Throughout, any clearer spells overnight may lead to localised frost and fog.
