Outlook for Monday to Wednesday:

A rather changeable start to this period, with frontal systems moving east across the UK and bringing spells of rain and strong winds for many areas, though interspersed with quieter interludes. Overall, rain is most likely across the north and west, while southeast parts may be relatively drier, though not completely dry. Moving into the second week of December, there are signs of more settled weather developing more widely, especially across the south and southwest of the UK. This may well bring a spell of mainly dry conditions in these areas, probably with patchy overnight frost and fog. Any outbreaks of rain and wind in this period are more likely to affect the north. Temperatures will vary around average for December, with some milder and some colder days.

Initially, high pressure is likely to be dominant, especially across the south, with relatively settled conditions likely overall. Frontal systems may still affect north and northwest UK at times, although probably fairly weak. Moving into the second half of December, a period of more unsettled conditions appears likely for a time, bringing a greater prevalence of rain and showers to most areas but especially the northwest. Some of the showers could be wintry, especially on high ground. Later in the month, there are signals that higher pressure may become re-established, with more settled conditions likely to develop, particularly across the south. Temperatures are likely to be around average overall, with colder interludes bringing frost and fog.
